Why the PM80 Is an 100A CNC Machine Torch
The PM80 should be treated as a dedicated machine-torch product rather than as a generic 100A plasma torch.
The current machine-torch consumable architecture reaches its primary cutting range at approximately 70–100A, using a Ø1.3 mm back-striking cutting tip.
This makes 100A the most technically consistent product identity for the PM80 platform.
Dedicated Machine Torch Geometry
Unlike a handheld plasma torch, the PM80 uses a straight machine-oriented torch structure designed for fixed mounting.
A dedicated CNC torch helps maintain:
Torch perpendicularity
Repeatable pierce position
Controlled cutting height
Stable kerf geometry
Repeatable part dimensions
Machine-Controlled Operation
The PM80 is controlled through the plasma power source and CNC system rather than by a manual trigger.
A typical CNC cycle can include:
Torch positioning
Initial-height sensing
Plasma start
Piercing
Cutting motion
Torch-height adjustment
Arc stop
PM80 HF Back-Striking Arc Starting
The PM80 uses a HF back-striking system.
This means the torch does not rely on a conventional high-frequency ignition circuit.
Internal movement between the electrode and cutting tip forms part of the pilot-arc starting sequence.
For this reason, the following components should be treated as a matched system:
Torch head
Electrode
Diffuser
Cutting tip
Retaining component
Gas supply
HF and HF torches should not be interchanged solely because the current rating or connector appears similar.
Why HF Starting Is Relevant for CNC Plasma Cutting
A CNC cutting system contains electronic components such as:
A HF torch avoids the conventional high-frequency ignition pulse used by HF plasma systems.
However, HF starting alone does not guarantee compatibility.
The plasma power source must still match:

Ø1.3 mm / 70–80A / Back-Striking
This Ø1.3 mm configuration is the most important full-output cutting tip for an 80A PM80 product page.
Why Current-to-Nozzle Matching Matters
The PM80 should not use one nozzle size for every cutting current.
Correct tip selection helps maintain:
Stable arc behavior
Correct gas flow
Appropriate kerf width
Better consumable life
More consistent cutting
Using a lower-current nozzle at excessive amperage can accelerate nozzle wear and reduce cutting stability.
For distributors and service companies, the current-to-nozzle relationship should be published prominently rather than buried in a spare-parts table.
PM80 Gouging Tip
The current PM80 consumable family includes:
INWELT Code: IJWV1686-16
Reference: 51311G.16
Description:
Ø1.6 mm / 80A Gouging Tip / Back-Striking
Plasma gouging removes metal without completely cutting through the plate.
Potential applications include:
Weld removal
Defect removal
Back-gouging
Joint preparation
Repair work
Gouging should only be used when the plasma power source and automated cutting system support the required process.
PM80 Back-Striking Electrode
The current PM80 electrode is:
INWELT Code: IJWC1670
Reference: 52558
Description:
Back-Striking Plasma Electrode
The electrode forms an important part of both arc starting and plasma cutting.
Inspect the electrode regularly and replace it before excessive wear contributes to:
Difficult arc starting
Unstable pilot arc
Accelerated nozzle wear
Inconsistent cutting
Do not grind or mechanically modify a severely worn electrode.
PM80 Gas Diffuser
The current diffuser is:
INWELT Code: IJWG1676
Reference: 60027
The diffuser controls process-gas distribution around the electrode and nozzle.
Correct gas flow contributes to:
Arc stability
Consumable cooling
Plasma-jet shape
Cutting consistency
Replace the diffuser if it becomes:
Cracked
Burned
Deformed
Heavily contaminated
PM80 Retaining and Outside Nozzle Components
The standard front-end system currently includes:
INWELT Code: IJWT1678-05
Reference: 60510
Description:
Gray Glass-Fiber Outside Nozzle / Retaining Component
A separate gouging outside-nozzle configuration is also available:
INWELT Code: IJWT1683-05
Reference: 60511
Use the correct component for standard cutting or gouging.
Do not mix gouging and normal cutting front-end components without confirming the complete consumable stack.
PM80 Machine Torch Head
The current machine-torch head is:
INWELT Code: IJWA0632
Description:
PM80 / PTM80-Type Machine Torch Head
This machine-specific torch head should be one of the primary components shown on the product page.
The related torch-head components include:
IJGU0710 / 51620.60 – O-Ring
and
IJAO0784 / 09800.42 – Air / Cooling Tube
These components should remain clearly associated with the machine-torch assembly.
PM80 Machine Body and Cable Support
The current machine-torch assembly also includes:
INWELT Code: IJIK0121
Description:
Plasma Machine Handle / Body Kit
Cable-support options include spring-support components for:
These parts should be described as machine-body and cable-support components, not as ergonomic operator handles.
PM80 Cable Assembly Options
The PM80 machine-torch platform includes several cable arrangements.
Current examples include:
6 m 1/4G Integrated Cable
IJWO11210074-22
12 m 1/4G Integrated Cable

However, physical connector fit alone does not confirm compatibility.
Always verify:
Pin functions
Plasma start circuit
Pilot-arc arrangement
Gas/current interface
Machine control wiring
How to Check PM80 CNC Plasma Cutter Compatibility
Do not select the PM80 only because a machine is labeled CUT80 or 80A.
Several technical factors must match.
Confirm the Starting Architecture

Add a PM80 Machine-Torch Dimension Drawing
Machine-torch dimensions are especially important for CNC integration.
INWELT should publish an original dimension drawing showing:
Do not copy dimensions from another PTM80 supplier.
Measure the actual INWELT PM80 production torch and publish first-party data.
This is one of the strongest technical additions you can make for SEO, GEO and B2B buyers.
PM80 and CNC Torch Height Control
A CNC plasma table may use automatic torch-height control.
Possible systems include:
Arc-Voltage THC
After the cutting arc is established, the THC system can use arc voltage as part of maintaining the programmed torch height.
The correct value depends on:
Plasma power source
Material
Plate thickness
Current
Tip diameter
Cutting speed
Do not publish one universal THC voltage for the PM80.
Piercing Height vs. Cutting Height
Mechanized plasma cutting normally uses different heights during piercing and continuous cutting.
Piercing Height
Molten metal is expelled upward while the plasma arc penetrates the plate.
Correct pierce height can reduce molten-metal damage to the nozzle and retaining components.
Cutting Height
After the pierce is complete, the torch moves to the programmed cutting height.
Incorrect cutting height can contribute to:
Use tested parameters from the complete plasma power source and PM80 torch system.
How Thick Can the PM80 CNC Plasma Torch Cut?
The current webpage states cutting capacities of up to 35 mm.
This should not be presented as a universal torch-only guarantee.
Cutting capacity depends on:
Plasma power source
Input power
Material
Cutting current
Cutting-tip diameter
Gas pressure
Gas flow
Travel speed
Pierce height
Cutting height
Consumable condition
Required edge quality
Professional plasma specifications should distinguish between:
Recommended Cutting Capacity
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.
Publish specific PM80 thickness figures only when supported by an INWELT complete-system cutting test.
Build an INWELT PM80 CNC Cut Chart
A verified first-party cut chart would significantly strengthen this page for professional buyers and search engines.
Recommended fields include:
| Parameter | Data to Publish |
| Material | Mild Steel / Stainless Steel / Aluminum |
| Thickness | Tested thickness |
| Current | 40A / 50A / 60A / 70A / 80A |
| Tip Code | INWELT part number |
| Tip Diameter | Ø1.0 / Ø1.1 / Ø1.2 / Ø1.3 mm |
| Gas Pressure | bar |
| Gas Flow | L/min |
| Travel Speed | mm/min |
| Pierce Height | mm |
| Pierce Delay | seconds |
| Cutting Height | mm |
| Kerf Width | mm |
| Result | Recommended / Maximum / Severance |
Use measured INWELT cutting data rather than competitor values.
Recommended Process Gas for the PM80
The PM80 architecture should use the process-gas specification approved for the compatible plasma power source.
Before final publication, INWELT should confirm and publish:
Process gas
Operating pressure
Gas flow
Post-flow time
The current page's existing 100A/HF/220 L/min specification should not be retained if the final product is confirmed as the 80A HF back-striking PM80 configuration.
Use Clean and Dry Process Gas
Contaminated compressed air can negatively affect:
Arc stability
Electrode life
Cutting-tip life
Cutting quality
Use suitable filtration and moisture separation.
What Materials Can the PM80 Cut?
When connected to a compatible plasma power source, the PM80 can cut electrically conductive materials including:
