PMX Series Non-HF Plasma Cutting Torches for Manual and CNC Cutting

The INWELT PMX Series is a family of air-cooled, non-high-frequency plasma cutting torches designed for professional manual cutting and mechanized CNC applications.

The current range includes two main product groups:

Manual / Handheld Torches

• PMX45 – 45A

• PMX65 – 65A

• PMX85 – 85A

• PMX105 – 105A

CNC / Mechanized Torches

• PMX-M45 – 45A

• PMX-M65 – 65A

• PMX-M85 – 85A

• PMX-M105 – 105A

The series uses Air/N₂ as the process gas and supports multiple cutting-current levels, consumable configurations, cable assemblies and rear connections.

Manual and machine torches should be treated as separate product configurations even when they share related consumables.

Manual PMX vs. PMX-M CNC Torch: What Is the Difference?

The main difference is how the torch is operated and mounted.

Do not install a manual torch as a substitute for a dedicated machine torch without verifying the complete system requirements.

How to Choose the Correct PMX Current Class

The correct current class depends on the plasma power source and cutting requirement.

PMX45 / PMX-M45

Primary current:

45A

PMX65 / PMX-M65

Primary current:

65A

PMX85 / PMX-M85

Primary current:

85A

PMX105 / PMX-M105

Primary current:

105A

A higher-current torch does not automatically mean it should be used at full output for every cut.

The nozzle, shield and other consumables must be matched to the selected operating current.

PMX Series Cutting Tip Selection by Current

The current INWELT PMX consumable system follows a current-specific nozzle approach.

Typical full-current relationships include:

The exact part number depends on torch model, manual/machine configuration and consumable family.

Do not select a plasma cutting tip only by physical appearance.

Why Current-to-Nozzle Matching Matters

The cutting nozzle constricts the plasma arc.

Nozzle diameter affects:

• Plasma-jet shape

• Gas velocity

• Kerf width

• Current capacity

• Consumable temperature

Using a low-current nozzle at excessive amperage can result in:

• Rapid nozzle wear

• Enlarged orifice

• Unstable arc

• Wider kerf

• Poor cut quality

Use the nozzle specified for the selected current.

PMX Series Electrodes

The electrode transfers electrical energy into the plasma arc.

The current PMX family uses replaceable electrodes matched to the relevant torch and consumable platform.

Inspect the electrode for:

• Excessive central pit depth

• Burning

• Cracking

• Contamination

• Mechanical damage

An excessively worn electrode can accelerate nozzle wear and reduce arc-starting reliability.

PMX Series Swirl Rings

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

Correct gas swirl helps stabilize and constrict the plasma arc.

Different current classes can require different swirl-ring configurations.

Do not assume one swirl ring is correct for every PMX45–105 process.

Use the verified INWELT consumable relationship.

Hand Shields vs. Machine Shields

Manual and mechanized plasma cutting can require different front-end shield configurations.

Hand Torch Shields

Typical hand processes can include:

• Drag cutting

• Stand-off cutting

• Gouging

Machine Torch Shields

Mechanized processes can require:

• Machine cutting shield

• Stand-off configuration

• CNC retaining components

• Process-specific front end

Do not automatically install a hand shield on a machine torch or a machine shield on a manual torch.

Cutting vs. Gouging Consumables

Selected PMX configurations can support plasma gouging when the correct consumables are installed.

Cutting

Cutting consumables are designed to create a narrow plasma jet for material separation.

Gouging

Gouging consumables create a wider arc for controlled metal removal.

Typical gouging applications include:

• Weld removal

• Defect removal

• Back-gouging

• Joint preparation

• Repair and rework

Use the correct gouging nozzle and shield for the selected current.

Non-HF Plasma Arc Starting

The current INWELT PMX Series is positioned around non-high-frequency arc-starting systems.

This distinction is important for replacement projects.

A non-HF PMX torch should not automatically replace:

• An HF torch

• A different pilot-arc architecture

• A torch with incompatible control wiring

Before replacement, confirm:

• Starting method

• Pilot-arc circuit

• Plasma power-source output

• Rear connector

• Trigger or CNC wiring

Why Non-HF Starting Matters for CNC Systems

CNC plasma systems can include sensitive electronics such as:

• CNC controller

• Torch-height controller

• Motor drives

• Computer interfaces

• Signal cables

Non-HF plasma starting avoids the conventional high-frequency ignition architecture used by HF-start plasma systems.

However, non-HF operation alone does not guarantee CNC compatibility.

The complete power-source, torch and control system still needs to match.

PMX Series Process Gas Requirements

Current INWELT PMX torches use:

Air / N₂

as the listed process-gas options.

Approximate current-category values are:

Use clean, dry process gas according to the plasma power-source requirements.

Contaminated or moisture-laden compressed air can negatively affect consumable life and cutting consistency.

PMX Series Recommended Post-Flow

Current INWELT configurations list different recommended post-flow periods according to torch class.

Post-flow helps remove residual heat from the torch and consumables after cutting.

Allow the power source to complete its normal cooling cycle whenever possible.

PMX Series Cable and Connector Options

The PMX range supports multiple rear-connection arrangements depending on the specific torch.

Available configurations can include:

• 1/4G integrated

• 1/4G separated

• Central adapter

• Custom adapter

• 2-wire control

• 4-wire control

• Coaxial cable

Compatibility should never be determined only from thread size or connector appearance.

Confirm the complete interface.

How to Check PMX Plasma Cutter Compatibility

Do not select a replacement torch only because the plasma cutter is labeled 45A, 65A, 85A or 105A.

Confirm the following.

Rated Output Current

The power source must operate within the verified range of the selected torch and consumables.

Arc-Starting System

Confirm that the machine uses a compatible non-HF architecture.

Pilot-Arc Circuit

Pilot-arc design can differ between plasma systems.

Rear Connector

Check:

• Thread

• Central adapter

• Power/gas path

• Pilot connection

Control Wiring

Manual and machine configurations can use different:

• Trigger wires

• Start signals

• CNC interfaces

Process Gas

Confirm pressure and flow requirements.

PMX CNC Torch Mounting Requirements

For PMX-M machine torches, physical mounting dimensions are critical.

INWELT should publish first-party dimension drawings showing:

• Torch-body diameter

• Overall torch length

• Clamping-zone length

• Nozzle-to-clamp distance

• Cable exit

• Minimum clearance

These dimensions should be measured from actual INWELT production torches.

Do not copy another manufacturer's machine-torch drawing.

PMX Machine Torch and Torch Height Control

CNC plasma tables can use torch-height-control systems to manage cutting height.

Depending on the complete plasma system, height control can involve:

• Initial-height sensing

• Arc-voltage THC

• Mechanical floating head

• Other machine-specific sensing methods

Do not claim ohmic sensing compatibility unless the exact:

• Shield

• Retaining component

• Electrical connection

• CNC interface

has been verified for the INWELT configuration.

Piercing Height vs. Cutting Height

Mechanized plasma cutting commonly uses different torch heights during piercing and cutting.

Piercing Height

The torch remains farther from the plate while molten material is expelled during arc penetration.

Cutting Height

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

Incorrect height can contribute to:

• Excessive bevel

• Dross

• Nozzle damage

• Poor dimensional accuracy

• Reduced consumable life

Use verified process data from the complete plasma system.

How Thick Can PMX Series Plasma Torches Cut?

A plasma torch alone does not define one universal cutting thickness.

Cutting capacity depends on:

• Plasma power source

• Current

• Material

• Nozzle

• Gas pressure

• Gas flow

• Travel speed

• Pierce height

• Cutting height

• Consumable condition

• Required cut quality

Professional data should distinguish between:

Recommended Cut

Productive cutting with acceptable speed and edge quality.

Maximum Cut

Thicker material that can still be cut at lower speed.

Severance

Maximum thickness that can be separated, usually with reduced edge quality.

Do not publish one generic thickness figure for all PMX torches.

Build INWELT PMX Cut Charts

One of the strongest future SEO and GEO improvements would be verified INWELT cut charts.

Recommended fields include:

Use measured INWELT data rather than competitor cut charts.

What Metals Can PMX Series Plasma Torches Cut?

When connected to a compatible plasma power source, PMX Series torches can cut electrically conductive materials including:

• Mild steel

• Carbon steel

• Stainless steel

• Aluminum

• Copper

Actual cut performance depends on the complete plasma system.

Typical Applications for Manual PMX Torches

Handheld PMX torches can be used for:

• General fabrication

• Repair

• Maintenance

• Structural steel

• Agricultural equipment

• Construction equipment

• Automotive fabrication

• Metal workshops

PMX-M machine torches are intended for:

• CNC plasma tables

• Automated plate cutting

• Profile cutting

• Sheet-metal production

• Structural fabrication

• Machinery components

• Production cutting cells

• Industrial automation

Machine integration should always consider torch dimensions, connector, starting system and control interface.

Manual and Machine Consumables Should Be Clearly Separated

Some PMX hand and machine configurations can share selected internal consumables.

However, the complete front-end system should not automatically be treated as identical.

Clearly distinguish:

• Hand shield

• Machine shield

• Drag-cut configuration

• Mechanized configuration

• Gouging configuration

This is especially important on 45A, 65A, 85A and 105A product pages.
