INWELT PMX-M105 105A Non-HF CNC Plasma Cutting Torch

105A Non-HF CNC Plasma Cutting Torch for Mechanized Cutting

The INWELT PMX-M105 is an air-cooled CNC and mechanized plasma cutting torch designed for automated plasma tables, profile-cutting machines, plate-processing equipment and industrial metal-cutting systems.

The PMX-M105 should be positioned primarily as a 105A machine torch with a 60% duty cycle using a non-high-frequency arc-starting system.

The current INWELT technical configuration includes:

• 105A primary rated current

• 60% duty cycle

• Air/N₂ process gas

• Non-HF arc starting

• Approx. 5.0–5.5 bar gas pressure

• Approx. 255 L/min gas flow

• Approx. 120-second recommended post-flow

• Standard 6 m torch lead

• 45A / 65A / 85A / 105A related cutting-consumable family

Multiple rear-connection and cable arrangements are available, including integrated, separated, central-adapter, custom-adapter and coaxial configurations.

The PMX-M105 should remain clearly separated from the PMX105 handheld torch and from any separately verified PMX-M105P higher-current variant.

INWELT PMX-M105 Technical Specifications

Before ordering, confirm the plasma power source, operating current, non-HF starting architecture, rear connector, control wiring and CNC interface.

PMX-M105 Machine Torch vs. PMX105 Hand Torch

PMX-M105 and PMX105 belong to the same wider product family but should be treated as separate complete torch products.

Some consumables and internal components may be shared across related platforms.

However, complete torch assemblies, shields, machine bodies, handles and cable/control configurations should not automatically be treated as interchangeable.

Use descriptive internal-link anchors such as:

PMX-M105 CNC Plasma Cutting Torch

and

PMX105 Manual Plasma Cutting Torch

rather than referring to both products only as “PMX105.”

Why Use a Dedicated 105A Machine Torch for CNC Plasma Cutting?

A CNC plasma system requires more than an arc-capable torch.

The torch must provide repeatable geometry, stable mounting and a compatible machine-control interface.

Stable Machine-Torch Geometry

A fixed machine torch allows the CNC system to maintain:

• Torch perpendicularity

• Repeatable pierce position

• Controlled cutting height

• Stable kerf

• Consistent cutting direction

• Repeatable part geometry

Machine-Controlled Start Sequence

The cutting cycle is controlled through the plasma power source and CNC system rather than by a hand trigger.

A typical mechanized process includes:

1. Torch positioning

2. Initial-height sensing

3. Plasma start

4. Piercing

5. Cutting movement

6. Torch-height adjustment

7. Arc stop

Higher-Current Mechanized Platform

The 105A platform provides additional current capacity compared with 45A, 65A and 85A machine-torch systems.

The actual current should still be selected according to material thickness, cutting process and the tested cut chart of the complete plasma system.

How the PMX-M105 Non-HF Plasma System Works

The PMX-M105 operates as part of a complete mechanized plasma system consisting of:

• Plasma power source

• PMX-M105 machine torch

• CNC controller

• Process-gas supply

• Cutting table

• Work connection

• Optional torch-height-control system

Non-HF Arc Starting

The PMX-M105 uses a non-high-frequency starting system.

It does not rely on a conventional HF ignition circuit.

The plasma power source must therefore use a compatible non-HF starting architecture.

Do not replace an HF machine torch with the PMX-M105 solely because the current rating or rear connector appears similar.

Plasma Arc Formation

Air or nitrogen enters the torch and flows through the electrode, swirl ring and cutting nozzle.

Electrical energy ionizes the process gas and produces a concentrated plasma arc.

The nozzle constricts the arc so that thermal energy melts electrically conductive material while the gas removes molten metal from the kerf.

Post-Flow Cooling

The current INWELT specification recommends approximately 120 seconds of post-flow.

Continued gas flow after cutting helps remove residual heat from the torch head and front-end consumables.

Allow the plasma system's normal post-flow cycle to complete whenever possible.

Why Non-HF Starting Matters for CNC Systems

CNC plasma equipment contains electronic controllers, motion drives, height-control electronics and communication wiring close to the plasma process.

A non-HF starting system avoids the conventional high-frequency ignition circuit used by some plasma platforms.

However, non-HF does not mean universally compatible.

The following must still match:

• Plasma power source

• Pilot-arc architecture

• Start circuit

• Rear connector

• Control wiring

• Gas requirements

• CNC interface

The appropriate positioning is therefore:

PMX-M105 is designed for compatible non-HF mechanized plasma cutting systems.

PMX-M105 45A, 65A, 85A and 105A Mechanized Cutting Consumables

A strong 105A CNC platform should clearly separate its consumables by cutting current.

The wider INWELT PMX family supports multiple current levels so the same higher-output plasma system can use different process configurations.

45A Mechanized Cutting

A 45A setup can be useful for thinner materials where lower heat input and a smaller kerf are preferred.

65A Mechanized Cutting

A 65A configuration provides an intermediate current range for general CNC cutting.

85A Mechanized Cutting

The 85A configuration provides additional cutting output while remaining below the maximum PMX-M105 rating.

105A Mechanized Cutting

The 105A configuration is the primary full-output cutting setup for the PMX-M105.

The nozzle, electrode, swirl ring, retaining component and shield should be matched to the selected current and process.

Do not operate a lower-current nozzle at 105A unless the exact consumable configuration is approved for that current.

PMX-M105 Cutting Tip Selection

The current INWELT page contains several PRO cutting tips.

45A Tip

INWELT Code: IJWV0664-09

Specification:

Ø0.9 mm / 45A / PRO

65A Tip

INWELT Code: IJWV0664-11

Specification:

Ø1.1 mm / 65A / PRO

85A Tip

The current page lists:

IJWV0664-13 – Ø1.3 mm

However, its current description appears to be incorrectly labeled as 65A.

Verify internally whether this is the intended 85A configuration before publishing the final current mapping.

105A Tip

The current page lists:

IJWV0664-15 – Ø1.5 mm

Its current description also appears to be incorrectly labeled as 65A.

Verify internally whether this is the intended 105A configuration before publishing it as the standard PMX-M105 nozzle.

For SEO and GEO, a verified current-to-tip table is much stronger than publishing contradictory part descriptions.

Keep 125A PMX-M105P Parts Separate from PMX-M105

The current spare-parts table also includes:

IJWV0664-18 – higher-current / 125A-related PRO tip

and complete torch assemblies labeled PMX-M105P.

This should not automatically change the primary PMX-M105 product rating from 105A to 125A.

Recommended structure:

PMX-M105 = 105A CNC machine torch

PMX-M105P = separate higher-current variant, only if technically verified

If the PMX-M105P is a genuine 125A product, give it either:

• A separate product page, or

• A clearly separated variant section with its own verified technical specification

Do not use 105/125A as the main H1 or Product structured-data rating.

PMX-M105 105A Swirl Ring

The current INWELT 105A swirl ring is:

INWELT Code: IJWG3003

Application:

PMX105 / 105A

The swirl ring controls the distribution and rotation of process gas around the electrode and nozzle.

Correct gas flow helps maintain:

• Arc stability

• Plasma-jet shape

• Consumable cooling

• Repeatable cutting

Replace the swirl ring if it becomes:

• Cracked

• Burned

• Distorted

• Heavily contaminated

Do not enlarge or modify the gas passages.

PMX-M105 Electrode

The current product family lists:

INWELT Code: IJWC0043

Application:

PMX65 / PMX85 / PMX105 family

The electrode transfers electrical energy through the torch.

A wear pit develops at the center during operation.

Replace the electrode before excessive erosion causes:

• Failed starts

• Unstable arc behavior

• Accelerated nozzle wear

• Inconsistent CNC cutting

For automated production, monitor electrode condition regularly because repeated piercing cycles can accelerate consumable wear.

PMX-M105 Machine Torch Head

The current INWELT machine head is:

INWELT Code: IJWA0662

Description:

PMX65 / PMX85 / PMX105 Machine Plasma Torch Head

The related O-ring is:

INWELT Code: IJGU0686

Specification:

Ø17 × 20.6 × 1.8 mm / Red Silicone

This dedicated machine head should be one of the primary components shown on the product page.

The current manual handle and trigger components should not be presented as the main PMX-M105 service parts.

PMX-M105 Machine Shield and Retaining Components

The current live parts table mixes hand-torch shield descriptions with a machine-torch product.

That should be corrected before publishing the final spare-parts structure.

For a PMX-M105 machine page, the primary front-end stack should identify the verified:

1. Machine shield

2. Retaining component

3. 105A cutting tip

4. Electrode

5. 105A swirl ring

Do not publish a hand-torch shield as the default PMX-M105 shield merely because it belongs to the same general PMX product family.

Once the correct machine shield code is verified, place it directly beside the 105A nozzle and retaining component in the parts table.

PMX-M105 Outside Nozzle Options

The current product family lists both 6-hole and 10-hole outside-nozzle configurations.

Before publication, verify:

• Correct INWELT code

• Compatible current range

• Machine vs. hand use

• Cutting vs. gouging application

Front-end gas passages should remain clean and undamaged.

Replace any outside-nozzle component that is cracked, distorted or heavily contaminated.

PMX-M105 Complete Torch Configurations

The current INWELT range includes several 6 m PMX-M105 assemblies.

The current table also includes related PMX-M105P versions.

Keep the 105A PMX-M105 configurations first, and place PMX-M105P in a clearly separate variant table only if its rating has been verified.

PMX-M105 Cable Assembly Options

The current INWELT cable family includes:

These exact configurations are valuable for plasma equipment manufacturers and distributors because they help identify the correct replacement machine torch.

PMX-M105 Central Adapter

The current product system includes:

INWELT Code: IJAY0089

Description:

5-Pin Plasma Torch-Side Central Adapter

A central adapter can simplify installation on compatible plasma power sources.

However, connector appearance alone does not confirm compatibility.

Always verify:

• Pin functions

• Start circuit

• Pilot-arc arrangement

• Control wiring

• Gas/current interface

before installation.

How to Check PMX-M105 CNC Plasma Cutter Compatibility

A PMX-M105 should not be selected simply because a machine is described as 100A or 105A.

Confirm Non-HF Starting

The power source must support a compatible non-HF torch architecture.

Confirm the Current Range

The primary PMX-M105 product should be operated within its verified 105A rating.

Confirm the Rear Connection

Available configurations include:

• 1/4G integrated

• 1/4G separated

• Central adapter

• Custom adapter

• Coaxial central-adapter configuration

Confirm Control Wiring

Current machine configurations include:

• 2-wire

• 4-wire

• Coaxial cable

Confirm CNC Integration

Check how the plasma power source and controller handle:

• Start command

• Arc-ok signal

• Divided arc voltage

• Torch-height control

• Fault signals

Provide Machine Information Before Ordering

For replacement or OEM projects, provide:

• Plasma power-source manufacturer

• Machine model

• Rated output current

• Existing torch model

• Main connector photographs

• Control connector photographs

• CNC controller information

This is more reliable than a generic brand-compatibility list.

PMX-M105 and CNC Torch Height Control

A CNC plasma system can use automatic torch-height control to maintain the intended distance between the torch and workpiece.

Possible methods include:

• Arc-voltage THC

• Floating-head sensing

• Ohmic sensing

• Other initial-height systems

Arc-Voltage Height Control

After the cutting arc is established, arc voltage can be used by a compatible THC system to help maintain cutting height.

The actual target voltage depends on:

• Plasma power source

• Current

• Material

• Plate thickness

• Cutting speed

• Consumables

Ohmic Sensing

Current competitor 105A machine systems offer dedicated ohmic retaining-cap or ohmic-ring configurations rather than treating ohmic sensing as an automatic torch feature.

For the INWELT PMX-M105, do not claim ohmic sensing until the specific machine shield/retaining cap and electrical connection have been verified.

If available, publish:

• INWELT part number

• Wiring diagram

• Compatible shield

• Installation instructions

This would be valuable first-party GEO content.

Piercing Height vs. Cutting Height

CNC plasma cutting normally uses different heights during piercing and continuous cutting.

Piercing Height

Molten metal is expelled upward when the plasma arc initially penetrates the plate.

Correct pierce height can reduce molten-metal damage to the nozzle and shield.

Cutting Height

After piercing, the torch moves to the programmed cutting height.

Incorrect height can contribute to:

• Excessive bevel

• Wider kerf

• Heavy dross

• Reduced consumable life

• Poor dimensional repeatability

Use parameters tested with the complete plasma system rather than copying another manufacturer's cut chart.

PMX-M105 Mechanized Cutting Speed

Cutting speed should be selected according to the complete plasma system.

Important variables include:

• Material

• Plate thickness

• Cutting current

• Cutting tip

• Gas pressure and flow

• Cutting height

• Consumable condition

• Required edge quality

Travel speed that is too slow can increase:

• Heat input

• Kerf width

• Low-speed dross

Travel speed that is too high can cause:

• Arc lag

• Incomplete penetration

• Poor edge quality

INWELT should therefore publish tested cutting-speed data rather than one universal speed recommendation.

How Thick Can the PMX-M105 Cut?

The current page states that the PMX-M105 cuts 10–15 mm under 60A.

This claim should be removed.

It conflicts directly with a machine torch whose primary product identity is 105A.

Actual cutting capacity depends on:

• Plasma power source

• Material

• Input power

• Cutting current

• Tip size

• Gas pressure and flow

• Travel speed

• Pierce height

• Cutting height

• Required cut quality

Professional plasma specifications should distinguish:

Recommended Cutting Capacity

Thickness that can be processed productively with acceptable speed and edge quality.

Maximum Cutting Capacity

Thicker material that can still be cut at reduced speed.

Severance Capacity

The maximum material thickness that can be separated, usually with reduced edge quality.

Publish specific PMX-M105 thickness values only after INWELT has verified them with a complete plasma-system test.

Build an INWELT PMX-M105 CNC Cut Chart

A first-party cut chart would be one of the strongest SEO and GEO assets for this product page.

Recommended fields include:

Use measured INWELT results rather than copying competitor system data.

Recommended Gas Supply for the PMX-M105

The current INWELT specification lists:

• Process gas: Air / N₂

• Gas pressure: approximately 5.0–5.5 bar

• Gas flow: approximately 255 L/min

• Recommended post-flow: approximately 120 seconds

Use Clean, Dry Process Gas

Moisture, compressor oil and particulate contamination can negatively affect:

• Arc stability

• Electrode life

• Nozzle life

• Cut consistency

Use appropriate filtration and moisture separation.

Check Gas Pressure During Flow

Static pressure can differ from actual pressure during operation.

Filters, regulators, fittings and long supply hoses can create pressure loss.

Set gas pressure according to the complete plasma system's operating procedure.

What Materials Can the PMX-M105 Cut?

When used with a compatible plasma system, the PMX-M105 can cut electrically conductive metals including:

• Mild steel

• Carbon steel

• Stainless steel

• Aluminum

• Copper

• Brass

• Galvanized steel

Actual cutting speed, edge quality and practical thickness depend on the complete plasma system.

PMX-M105 Mechanized Cutting and Plasma Gouging

The wider PMX105 consumable architecture includes both cutting and gouging-related components.

Mechanized Cutting

For the PMX-M105 page, CNC cutting should remain the primary product intent.

Machine consumables should be organized clearly by:

• 45A

• 65A

• 85A

• 105A

105A Plasma Gouging

The current parts table includes a separate 105A gouging-tip category.

Gouging removes metal without completely cutting through the workpiece.

Potential applications include:

• Weld removal

• Back-gouging

• Defect removal

• Joint preparation

Promote gouging only when:

• The plasma power source supports it

• The correct 105A gouging consumables are installed

• The automated machine can execute the required motion

Do not use standard cutting tips as gouging consumables unless approved for that process.

Typical Applications for the PMX-M105 CNC Torch

The PMX-M105 is suited to higher-output automated plasma cutting applications including:

• CNC plasma cutting tables

• Plate-processing systems

• Structural steel fabrication

• Heavy machinery manufacturing

• Construction equipment

• Agricultural equipment

• Truck and trailer manufacturing

• Railway fabrication

• Shipbuilding

• Industrial fabrication

• Automated production cells

• Automated profile cutting

The final torch configuration should always be selected according to the plasma power source and CNC interface.

PMX-M105 Maintenance for CNC Production

Consistent consumable condition is essential because worn components can affect every part produced by the CNC system.

Inspect the Electrode

Monitor the center wear pit.

Replace an excessively worn electrode before it causes failed starts or damages the nozzle.

Inspect the Cutting Tip

Check for:

• Enlarged orifice

• Oval opening

• Burn damage

• Contamination

A worn nozzle can affect:

• Bevel

• Kerf width

• Arc stability

• Dimensional repeatability

Inspect the Swirl Ring

Check for cracks, deformation, heat damage and contamination.

Inspect the Machine Shield

Keep gas passages clean and ensure the correct shield is installed for the selected current.

Inspect O-Rings

Check the torch-head seals for hardening, damage or gas leakage.

Inspect the Torch Lead

Make sure machine motion does not:

• Stretch the cable

• Crush the lead

• Create tight bends

• Interfere with the gantry or Z-axis
