INWELT PTM100 100A Non-HF CNC Plasma Cutting Torch

100A Non-HF CNC Plasma Cutting Torch for Mechanized Cutting

The INWELT PTM100 is an air-cooled CNC and mechanized plasma cutting torch designed for automated metal cutting, CNC plasma tables, profile-cutting machines and industrial fabrication systems.

The PTM100 is positioned around 100A operation with a 60% duty cycle and uses a non-high-frequency arc-starting system.

The current INWELT technical configuration includes:

• 100A rated current

• 60% duty cycle

• Air/N₂ process gas

• Non-HF arc starting

• Approx. 4.5–5.0 bar gas pressure

• Approx. 200 L/min gas flow

• Approx. 100-second recommended post-flow

• Standard 6 m torch lead

Multiple connection arrangements are available, including 1/4G integrated, 1/4G separate, central-adapter and coaxial cable configurations.

The PTM100 consumable family includes multiple cutting-tip sizes, electrodes, gas diffusers, shields and related service components for different current ranges and cutting processes.

INWELT PTM100 Technical Specifications

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

Why Use the PTM100 for CNC Plasma Cutting?

The PTM100 is designed specifically for machine-controlled plasma cutting rather than handheld operation.

100A Machine-Torch Platform

The PTM100 is positioned for compatible 100A-class plasma power sources.

This provides a higher-output platform for CNC cutting applications where lower-current 40A, 60A or 80A torches may not provide sufficient capacity.

Machine-Controlled Operation

The cutting sequence is controlled by the CNC/plasma system rather than a conventional hand trigger.

This allows the torch to operate as part of an automated cutting cycle that includes:

• Torch positioning

• Initial-height detection

• Arc start

• Piercing

• Cutting movement

• Torch-height adjustment

• Arc stop

Fixed Machine-Torch Installation

A machine torch is designed for stable mounting on a CNC Z-axis or torch holder.

Correct installation helps maintain:

• Torch perpendicularity

• Repeatable cutting height

• Stable piercing position

• Consistent kerf

• Repeatable part geometry

How the PTM100 Non-HF Plasma Cutting System Works

The PTM100 operates as part of a complete CNC plasma cutting system consisting of:

• Plasma power source

• PTM100 machine torch

• CNC controller

• Cutting table

• Process-gas supply

• Work connection

• Optional torch-height-control system

Non-HF Arc Starting

The PTM100 uses a non-high-frequency arc-starting architecture.

This is different from plasma systems that use a conventional high-frequency ignition circuit.

The plasma power source must therefore be designed for a compatible non-HF torch.

Do not replace an HF machine torch with the PTM100 based only on similar amperage or connector appearance.

Back-Striking Consumable Design

The current PTM100 consumable family uses a back-striking electrode/tip architecture.

During the starting sequence, the internal consumable movement helps initiate the pilot arc.

The correct electrode, nozzle, diffuser and torch head must therefore be used as a matched system.

Plasma Arc Formation

Air or nitrogen flows through the torch head, diffuser and nozzle.

Electrical energy ionizes the process gas and produces a high-temperature plasma arc.

The nozzle constricts that arc into a concentrated jet capable of cutting electrically conductive metal.

Why Non-HF Starting Matters for CNC Systems

CNC plasma tables contain electronic controllers, motor drives, height-control systems and signal cables near the plasma process.

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

However, non-HF starting does not mean the torch is automatically compatible with every CNC plasma cutter.

The following still need to match:

• Plasma power source

• Pilot-arc system

• Start/control wiring

• Main torch connection

• Gas interface

• CNC start circuit

The strongest product positioning is therefore:

PTM100 is designed for compatible non-HF CNC plasma cutting systems.

PTM100 vs. a Handheld 100A Plasma Torch

The PTM100 should be treated as a machine-torch product, not as a handheld torch with a different handle.

Some consumables may belong to the same broader product family, but the complete torch assemblies should not automatically be treated as interchangeable.

PTM100 Cutting Consumables by Current Range

The PTM100 consumable family covers several current ranges.

Different nozzle diameters are used because plasma-current level affects the required nozzle orifice, gas behavior and arc constriction.

40–50A Cutting Tip

The current parts family includes:

INWELT Code: IJWV1689-10

Specification:

Ø1.0 mm / 40–50A / Back-Striking

This lower-current configuration can be used where the complete plasma system supports reduced-amperage cutting.

50–60A Cutting Tip

INWELT Code: IJWV1689-11

Specification:

Ø1.1 mm / 50–60A / Back-Striking

60–70A Cutting Tip

INWELT Code: IJWV1689-12

Specification:

Ø1.2 mm / 60–70A / Back-Striking

80–90A Cutting Tip

INWELT Code: IJWV1687-14

Specification:

Ø1.4 mm / 80–90A / Back-Striking

100–110A Cutting Tip

INWELT Code: IJWV1687-15

Specification:

Ø1.5 mm / 100–110A / Back-Striking

This is the closest current band in the existing consumable list to the primary PTM100 100A product positioning.

Before labeling any nozzle as the official “100A standard tip,” confirm INWELT's tested current-to-nozzle specification internally.

How Should the 110–120A PTM100 Consumables Be Presented?

The current INWELT parts family also contains:

IJWV1687-16 – Ø1.6 mm / 110–120A

and a related 120A gouging tip.

These components should not automatically change the main PTM100 product rating from 100A to 120A.

Unless INWELT engineering has verified the complete PTM100 torch at 120A, present these parts as:

Related PT-series consumables subject to configuration verification

rather than making the H1, Product schema or primary specification table say “100–120A.”

One clear verified product rating is stronger for both buyers and search engines.

PTM100 Contact-Cutting Tips

The broader consumable system also includes contact-cutting tips.

Current configurations include:

• Ø1.0 mm / 40–50A

• Ø1.1 mm / 50–60A

• Ø1.2 mm / 60–70A

• Ø1.4 mm / 80–90A

• Ø1.5 mm / 100–110A

• Ø1.6 mm / 110–120A

Contact-cutting consumables should be used with the corresponding shield and diffuser configuration.

Do not mix contact-cutting and standard machine-cutting parts without confirming the complete consumable stack.

PTM100 Electrode

The current PTM100 family uses:

INWELT Code: IJWC1687

Reference:

52556

Description:

Plasma Electrode / PT100 Family

The electrode transfers electrical energy through the torch and forms part of the back-striking arc-starting system.

As the electrode wears, arc starting and cut consistency can deteriorate.

Replace the electrode before excessive wear causes:

• Failed starts

• Unstable plasma arc

• Accelerated nozzle wear

• Inconsistent CNC production

PTM100 Diffusers for Different Current Ranges

The current product family uses separate diffuser configurations.

30–70A Diffuser

INWELT Code: IJWG1673

Reference:

60025

Application:

Lower-current PT100 family configurations

80–120A Diffuser

INWELT Code: IJWG1672

Reference:

60026

Application:

Higher-current and related gouging configurations

The diffuser controls gas distribution around the electrode and nozzle.

Correct diffuser selection is therefore important for maintaining stable plasma flow.

PTM100 Retaining and Shield Components

The current family contains separate front-end components for different operating ranges and processes.

Examples include:

• 40–70A shield configuration

• 80–120A shield configuration

• Gouging shield configuration

• Standard outside nozzle

• Contact-cutting outside nozzle

For the PTM100 CNC page, prioritize verified machine-torch retaining and shield components.

If a component is intended only for the handheld torch, move it to the corresponding manual-torch page rather than listing it as a primary PTM100 component.

PTM100 Machine Torch Head

A dedicated machine torch should use a straight machine-oriented head and mounting structure.

For the final live page, INWELT should publish the verified PTM100 machine-torch head code together with:

• Torch body diameter

• Overall body length

• Usable clamping length

• Cable exit position

• Gas/current connection drawing

These dimensions are particularly valuable to CNC machine builders because they determine whether the torch fits the Z-axis and torch holder.

Add a PTM100 Machine-Torch Dimension Drawing

For a CNC product page, a dimension drawing can be more useful than several generic marketing paragraphs.

The drawing should include:

• Torch body diameter

• Overall torch length

• Clamp zone

• Distance from clamp to nozzle

• Cable exit

• Minimum mounting clearance

• Connector dimensions

Do not copy competitor dimensions.

Publish measurements from the actual INWELT PTM100 production torch.

PTM100 Cable and Connection Options

The current PTM100 product positioning includes several connection arrangements.

Available configurations include:

• 1/4G integrated

• 1/4G separate

• Central adapter

• Coaxial cable / central adapter

The standard page configuration uses a 6 m torch lead.

Additional lead lengths may be available depending on configuration.

For every complete torch SKU, the final product table should identify:

• Lead length

• Gas/current connection

• Start/control wiring

• Central adapter type

• Coaxial or conventional lead

This helps distributors select the correct replacement torch without relying on appearance alone.

Integrated vs. Separate PTM100 Connection

Integrated Connection

An integrated arrangement combines specified interfaces within the selected torch connection system.

This can simplify installation on compatible power sources.

Separate Connection

A separate configuration uses individually arranged power, gas or control interfaces according to the machine design.

Central Adapter

A central connector provides a multi-function torch-to-machine connection where the plasma cutter is designed for that interface.

A connector that physically fits does not guarantee electrical compatibility.

Always verify pin functions and machine wiring before installation.

Coaxial Cable Configuration

A coaxial torch lead integrates conductors within a dedicated cable architecture.

Where the PTM100 is supplied with a coaxial configuration, the plasma power source must use the corresponding torch connection.

Do not substitute a coaxial cable assembly with a conventional cable only because both leads use the same length.

How to Check PTM100 CNC Plasma Cutter Compatibility

A PTM100 should not be selected only because the machine is rated at approximately 100A.

Confirm the Starting System

The plasma power source must use a compatible non-HF / back-striking torch architecture.

Confirm the Operating Current

The primary PTM100 product on this page should remain positioned around 100A.

Confirm the Rear Connector

Identify whether the plasma cutter requires:

• 1/4G integrated

• 1/4G separate

• Central adapter

• Coaxial central-adapter arrangement

• OEM-specific connection

Confirm Start and Control Wiring

The machine's start circuit must match the torch/cable configuration.

Confirm CNC Interface

The CNC controller usually communicates with the plasma power source rather than directly operating the torch as a hand trigger would.

Verify:

• Start/stop signal

• Arc-ok signal

• Divided arc-voltage output where applicable

• Torch-height-control interface

Send Machine Information Before Ordering

For replacement projects, provide:

• Plasma cutter manufacturer

• Machine model

• Rated output current

• Existing torch model

• Main connector photographs

• Control plug photographs

• CNC controller

• Required lead length

This provides a much more reliable compatibility check than the statement “compatible with standard 100A CNC plasma cutters.”

PTM100 and Torch Height Control

A CNC plasma system often uses torch-height control to maintain the correct torch-to-work relationship during cutting.

Possible systems include:

• Arc-voltage THC

• Floating-head initial-height sensing

• Ohmic sensing

• Other mechanical or electrical surface-detection systems

Arc-Voltage Height Control

During cutting, the CNC system can use arc voltage as part of the process for maintaining torch height.

The exact voltage setting belongs to the complete plasma power source and cutting procedure.

Ohmic Sensing

Some PTM100-style machine-torch systems offer dedicated ohmic retaining-cap components.

Do not claim that the INWELT PTM100 supports ohmic sensing until the corresponding INWELT machine shield, retaining cap and electrical connection have been verified.

If available, publish the exact part number and wiring diagram.

Piercing Height vs. Cutting Height

Correct torch height is important for CNC plasma cutting.

Piercing Height

During piercing, molten material is expelled upward from the workpiece.

An appropriate pierce height helps reduce damage to the nozzle and shield.

Cutting Height

After the pierce is complete, the CNC system moves to the programmed cutting height.

Incorrect cutting height can contribute to:

• Excessive bevel

• Heavy dross

• Wider kerf

• Shortened consumable life

Use the tested parameters of the complete plasma cutting system.

PTM100 CNC Cutting Speed

Cutting speed should be determined using the complete plasma system rather than the torch rating alone.

Important variables include:

• Material

• Plate thickness

• Current

• Tip diameter

• Air pressure

• Cutting height

• Required edge quality

Travel that is too slow can increase:

• Heat input

• Kerf width

• Dross

Travel that is too fast can cause:

• Incomplete penetration

• Arc lag

• Poor edge quality

INWELT should eventually publish its own cut-speed chart for the PTM100.

How Thick Can the PTM100 Cut?

The current page claims 30–40 mm cutting capability and also refers to operation at 100–120A.

This should not be used as a universal torch-only specification unless supported by an INWELT system-level test.

Cutting capacity depends on:

• Plasma power source

• Material

• Input power

• Actual cutting current

• Tip size

• Air pressure and flow

• Travel speed

• Pierce height

• Cutting height

• Required edge quality

A professional plasma cutting specification should distinguish between:

Recommended Cut
Productive cutting with acceptable speed and edge quality.

Maximum Cut
Thicker material cut at reduced speed.

Severance
Maximum material thickness that can be separated, normally with lower edge quality.

Publish a specific thickness only after verifying the complete PTM100/power-source system.

Create an INWELT PTM100 CNC Cut Chart

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

Recommended fields include:

Use measured INWELT data rather than competitor specifications.

Recommended Gas Supply for the PTM100

The current INWELT technical data lists:

• Process gas: Air / N₂

• Gas pressure: approximately 4.5–5.0 bar

• Gas flow: approximately 200 L/min

• Recommended post-flow: approximately 100 seconds

Use Clean, Dry Process Gas

Moisture, oil and particulate contamination can reduce:

• Arc stability

• Electrode life

• Cutting-tip life

• Cut consistency

Use appropriate filtration and moisture separation.

Check Pressure During Gas Flow

Static regulator pressure may differ from actual operating pressure.

Filters, fittings, regulators and long air lines can create pressure drop.

Set the gas according to the complete plasma power source's operating procedure.

What Materials Can the PTM100 Cut?

When connected to a compatible plasma system, the PTM100 can cut electrically conductive materials including:

• Mild steel

• Carbon steel

• Stainless steel

• Aluminum

• Copper

• Brass

• Galvanized steel

The torch alone does not determine the maximum thickness for each material.

PTM100 Standard Cutting vs. Contact Cutting

The PTM100 consumable family includes parts intended for different cutting modes.

Standard Machine Cutting

Standard mechanized cutting uses the appropriate machine-torch front-end stack while the CNC system controls torch height.

Contact Cutting

Contact-cutting consumables use a different front-end relationship with the workpiece.

Do not assume that a contact-cutting shield or tip is appropriate for every CNC cutting program.

The correct front-end stack should match the cutting process and current range.

Can the PTM100 Be Used for Plasma Gouging?

The wider PT100 consumable family includes gouging-related components.

Gouging removes metal without cutting fully through the workpiece.

Typical uses include:

• Weld removal

• Back-gouging

• Defect removal

• Joint preparation

For the PTM100 machine-torch page, gouging should only be promoted if:

• The plasma power source supports the process

• The CNC or automation system supports the required motion

• Correct gouging consumables are installed

Mechanized cutting should remain the primary search intent of this product page.

Spare Parts Details:
