The PTM100 consumable family also includes several current-specific cutting tips, electrodes, diffusers and shields.

PT vs. PTM Plasma Cutting Torches

The most important distinction within the PT Series is the difference between handheld PT torches and PTM machine torches.

Feature	PT Manual Torches	PTM Machine Torches
Operation	Manual / Handheld	CNC / Mechanized
Torch Geometry	Hand torch	Straight machine torch
Start Control	Operator / power-source control	CNC / machine controlled
Mounting	Handheld	Fixed torch holder
Torch Height	Operator controlled	CNC / THC controlled
Main Use	Manual fabrication and repair	Automated production
Current Models	PT20 / PT40 / PT60 / PT80 / PT100	PTM60 / PTM100

Do not choose between PT and PTM torches according to amperage alone.

A PT60 hand torch and PTM60 machine torch can share related consumable architecture while still using different complete torch heads, bodies and control arrangements.

Why Choose a Non-HF PT Series Plasma Torch?

The PT Series is designed for compatible plasma cutting systems that do not rely on conventional high-frequency ignition.

Non-HF Starting Architecture

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

Depending on model, the PT Series can use pilot-arc or back-striking starting arrangements.

Relevant for Electronic and CNC Environments

Non-HF systems avoid the HF-start pulse generated by conventional high-frequency torches.

This can be relevant in cutting environments containing:

• CNC controls

• Computers

• Motor drives

• Electronic measurement systems

• Automation equipment

However, non-HF starting alone does not guarantee compatibility with a CNC machine.

The complete power source and control architecture must still match.

HF and Non-HF Torches Are Not Interchangeable

A non-HF PT torch should not replace an HF torch solely because the current rating or connector appears similar.

The starting system must match the plasma power source.

How to Choose the Correct PT Series Plasma Torch

Correct torch selection requires more than matching amperage.

Confirm Manual or CNC Operation

Choose a PT model for handheld cutting.

Choose a PTM model for CNC or fixed machine cutting.

Confirm the Plasma Power Source Current

Current PT Series ratings include:

• 20A

• 40A

• 60A

• 80A

• 100A

Select a torch whose verified rating matches the intended operating range.

Confirm Non-HF Starting Compatibility

The plasma power source must support the specific PT-style starting architecture.

Confirm Pilot Arc or Back-Striking Design

Starting technology varies by model.

Do not assume that every non-HF PT torch uses exactly the same internal starting mechanism.

Confirm the Rear Connection

Depending on model, configurations can include:

• Direct connection

• 1/4G

• Integrated connection

• Separate connection

• Central adapter

• OEM-specific connection

• Coaxial cable

Confirm Control Wiring

Different PT models and machine interfaces can use:

• 2-wire control

• 4-wire control

• Coaxial arrangements

The control circuit must match the plasma power source.

PT Series Back-Striking Consumable Systems

Several higher-output PT and PTM models use back-striking consumable architectures.

In a back-striking torch, internal movement between the electrode and nozzle forms part of the pilot-arc starting sequence.

For reliable operation, the following components should be treated as a matched system:

• Electrode

• Cutting tip

• Diffuser

• Shield

• Torch head

Do not combine standard and back-striking consumables unless the specific combination has been verified.

PT Series Cutting Tips by Current Range

One of the strongest technical features of the PT Series is the availability of model-specific cutting tips for different current ranges.

Depending on torch model, INWELT offers cutting tips for lower-current and higher-current configurations.

For example, PT80 and PT100-related consumable families include multiple nozzle diameters corresponding to different operating-current ranges.

The final individual product pages should identify:

Data Field	Information to Publish
INWELT Code	Exact part number
Reference	Cross-reference number
Tip Diameter	mm
Current Range	A
Torch Model	PT / PTM model
Process	Cutting / Contact Cutting / Gouging
Starting Type	Standard / Back-Striking

This type of first-party parts data is especially valuable for distributors and aftermarket buyers.

PT Series Electrodes, Diffusers and Shields

The PT Series is supported by a broad replacement-consumable system.

Depending on torch model, available components include:

• Standard electrodes

• Back-striking electrodes

• Extended electrodes

• Gas diffusers

• Swirl components

• Standard cutting tips

• Contact-cutting tips

• Extended tips

• Outside nozzles

• Shields

• Gouging consumables

• O-rings

• Torch heads

Exact components should always be matched to the specific model and current range.

Standard Cutting, Contact Cutting and Gouging

Some PT Series models support more than one plasma process.

Standard Cutting

Standard cutting uses the appropriate cutting tip and front-end stack for normal plate cutting.

Contact Cutting

Selected PT platforms include contact-cutting consumables.

Use only the shield and tip combination designed for contact operation.

Plasma Gouging

Higher-current PT families can include gouging components for:

• Weld removal

• Back-gouging

• Defect removal

• Joint preparation

• Repair and rework

The plasma power source must also support the selected process.

PT Series Connector and Cable Options

Different plasma power sources use different torch interfaces.

Depending on model, INWELT PT Series configurations can include:

• Direct cable assemblies

• 1/4G connections

• Integrated connections

• Separate connections

• Central adapters

• 2-wire control

• 4-wire control

• Coaxial machine-torch cables

• 4 m leads

• 6 m leads

• 12 m leads

For replacement orders, send photographs of the existing torch connector and control plug.

This is more reliable than selecting a torch only by amperage or external appearance.

How to Check PT Series Plasma Cutter Compatibility

A PT torch is not automatically compatible with every plasma cutter carrying the same amperage rating.

Before ordering, confirm:

Power Source Rating

The torch should operate within its verified current range.

Starting Architecture

The machine must support the required non-HF, pilot-arc or back-striking system.

Rear Connector

The power/gas connection must match.

Trigger or Control Wiring

Manual and machine torches may use different control circuits.

Pilot-Arc Circuit

Pilot-arc architecture must be compatible with the power source.

Gas Requirements

Pressure and flow vary significantly between PT20, PT40, PT60, PT80 and PT100.

Do not apply one model's gas specification to the entire PT Series.

PTM Series CNC Integration

PTM60 and PTM100 are designed for machine-controlled cutting.

For CNC integration, confirm:

• Machine torch-body dimensions

• Torch mounting diameter

• Usable clamping area

• Lead routing

• Start signal

• Arc-ok signal

• Torch-height-control interface

• Plasma power-source connection

INWELT should publish dimension drawings for each PTM machine torch because this first-party installation data is highly useful for CNC machine manufacturers and system integrators.

PTM Torches and Torch Height Control

A CNC plasma system may use automatic torch-height control.

Possible methods include:

• Arc-voltage THC

• Floating-head sensing

• Mechanical initial-height sensing

• Other compatible systems

The exact THC arrangement depends on the plasma power source and CNC controller.

Do not publish one universal arc-voltage or cutting-height setting for the entire PTM range.

What Metals Can PT Series Plasma Torches Cut?

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

• Mild steel

• Carbon steel

• Stainless steel

• Aluminum

• Copper

• Brass

• Galvanized steel

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

How Thick Can a PT Series Plasma Torch Cut?

There is no single cutting-thickness specification that applies to the entire PT Series.

Actual cutting capacity depends on:

• Plasma power source

• Torch model

• Input power

• Material

• Cutting current

• Tip diameter

• Gas pressure

• Gas flow

• Travel speed

• Torch height or stand-off

• Consumable condition

• Required edge quality

Professional cutting data should distinguish between:

Recommended Cutting Capacity

Material thickness that can be cut productively with suitable 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, generally with lower edge quality.

Use model-specific tested data rather than one universal PT Series thickness claim.

Build Model-Specific INWELT PT Series Cut Charts

INWELT should develop first-party cutting charts for individual torch and plasma power-source combinations.

Recommended fields include:

Parameter	Data to Publish
Torch Model	PT20 / PT40 / PT60 / PT80 / PT100 / PTM60 / PTM100
Material	Mild Steel / Stainless Steel / Aluminum
Thickness	Tested thickness
Current	Actual current
Tip Code	INWELT part number
Tip Diameter	mm
Gas Pressure	bar
Gas Flow	L/min
Cutting Speed	mm/min
Torch Height / Stand-Off	mm
Result	Recommended / Maximum / Severance

Verified first-party test data is more useful than generic claims about cutting capacity.
