INWELT PMX85 85A Non-HF Manual Plasma Cutting Torch

85A Non-HF Manual Plasma Cutting Torch for Professional Metal Cutting

The INWELT PMX85 is an air-cooled handheld plasma cutting torch designed for professional fabrication, maintenance, repair and industrial metal-cutting applications.

The current INWELT configuration is rated at 85A with a 60% duty cycle and uses a non-high-frequency arc-starting system.

Its main operating specifications include:

• 85A rated current

• 60% duty cycle

• Air/N₂ process gas

• Non-HF arc starting

• Approx. 5.0 bar operating pressure

• Approx. 230 L/min gas flow

• Approx. 80-second recommended post-flow

• Standard 6 m torch cable

Multiple rear-connection and control configurations are available, including 1/4G integrated, 1/4G separate, central-adapter, 2-wire, 4-wire and coaxial cable arrangements.

INWELT also supplies 45A, 65A and 85A cutting consumables together with electrodes, swirl rings, shields, torch heads, handles, trigger components, cable assemblies and gouging consumables.

INWELT PMX85 Technical Specifications

Before ordering, confirm the plasma power source, rated current, non-HF starting method, rear connector, trigger/control wiring and process-gas requirements.

How the PMX85 Non-HF Plasma Cutting Torch Works

The PMX85 operates as part of a complete plasma cutting system consisting of the torch, power source, process-gas supply and work connection.

Non-HF Arc Starting

The PMX85 uses a non-high-frequency starting system.

This means the torch does not depend on a conventional high-frequency ignition circuit to initiate the cutting sequence.

HF and non-HF plasma torches should not be treated as interchangeable.

The plasma cutter must use a start architecture compatible with the PMX85.

Plasma Arc Formation

Air or nitrogen enters the torch and passes through the electrode, swirl ring and nozzle assembly.

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

The cutting nozzle constricts that plasma stream so the concentrated arc melts electrically conductive material while the high-velocity gas removes molten metal from the kerf.

Post-Flow Cooling

The current INWELT specification recommends approximately 80 seconds of post-flow.

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

Allow the plasma cutter's normal post-flow cycle to finish whenever possible.

Why Choose the PMX85 for Manual Plasma Cutting?

The PMX85 is designed for higher-output manual plasma cutting than lower-current PMX45 and PMX65 torch systems.

85A Rated Capacity

The PMX85 is rated at 85A according to current INWELT technical data.

This provides a higher-current platform for professional fabrication and industrial repair.

60% Duty Cycle

The torch is specified at a 60% duty cycle.

Actual thermal load can also be influenced by:

• Operating current

• Ambient temperature

• Gas flow

• Number of arc starts

• Consumable condition

• Cutting technique

Do not routinely operate the torch above its verified rating.

Air-Cooled Construction

The PMX85 does not require a separate liquid-cooling unit.

Air/N₂ functions as the process gas and contributes to heat removal from the torch.

6 m Torch Lead

The standard 6 m cable assembly provides practical working reach for fabrication and maintenance environments.

PMX85 45A, 65A and 85A Cutting Consumables

A major advantage of an 85A-class plasma torch is that the consumable platform can support multiple cutting-current ranges.

Professional 85A systems also commonly separate 45A, 65A and 85A consumables rather than using a single nozzle for every current.

45A Cutting Configuration

A 45A consumable setup can be useful for:

• Thinner plate

• Reduced heat input

• Smaller kerf

• Lower-current cutting

65A Cutting Configuration

A 65A configuration provides an intermediate operating level.

This can be useful where more cutting capacity is needed than 45A without running the torch at full 85A output.

85A Cutting Configuration

The 85A configuration is intended for operation near the full rated current of the PMX85.

The nozzle, shield, electrode and swirl-ring combination should match the intended current.

Do not operate a 45A or 65A nozzle at 85A unless the consumable manufacturer specifically approves that configuration.

PMX85 Cutting Tip Selection

The current INWELT PMX family uses nozzle diameters corresponding to different operating ranges.

Typical configurations within the product family include:

Before publishing the final part-number-to-current table, verify each INWELT SKU internally.

The current live page appears to contain a labeling inconsistency in the Ø1.3 mm tip description, so the product page, technical catalog and ERP data should be synchronized before the exact mapping is presented as authoritative.

PMX85 Electrode and Swirl Ring

Electrode

INWELT Code: IVB0032

Application:

PMX65 / PMX85 / PMX105

The electrode transfers electrical energy through the torch.

As the electrode wears, a pit develops at the center.

Replace it before excessive erosion causes:

• Unstable arc starting

• Reduced cut consistency

• Increased nozzle wear

• Failed starts

Swirl Ring

INWELT Code: IVF3001

Application:

PMX65 / PMX85 / 45–85A

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

A cracked, contaminated or heat-damaged swirl ring can negatively affect plasma stability.

PMX85 Hand Torch Shield and Front-End Components

The current INWELT system includes hand-torch shield configurations for cutting and gouging.

PRO Hand Shield

INWELT Code: ISM0623

Application:

PMX65 / PMX85 / Hand / 45–85A / PRO

The shield helps protect the nozzle and establishes the intended relationship between the torch front end and workpiece.

Outside Nozzle

INWELT Code: IVS0693

Application:

PMX65 / PMX85 / PMX105 / 6-hole

Keep gas passages clean and replace damaged front-end components before cutting.

PMX85 Plasma Gouging

The PMX85 consumable family includes components for plasma gouging as well as cutting.

Gouging removes metal without cutting completely through the workpiece.

Typical applications include:

• Weld removal

• Defect removal

• Back-gouging

• Joint preparation

• Repair and rework

Professional 85A plasma systems also distinguish between cutting and dedicated 45–85A gouging consumables.

Do not use standard cutting tips as gouging consumables unless the specific configuration is designed for that purpose.

Drag Cutting vs. Stand-Off Cutting

Drag Cutting

A drag-cutting shield allows the torch to be guided along the material while maintaining the intended relationship between the nozzle and workpiece.

Drag cutting can be useful for manual fabrication and repair.

Do not drag an exposed nozzle directly across the plate unless the consumable is specifically designed for contact operation.

Stand-Off Cutting

In stand-off cutting, the nozzle is held a controlled distance above the workpiece.

This can reduce direct contact with the consumables and may be preferred for certain cutting applications.

Use the front-end configuration specified for the selected process.

PMX85 Complete Torch Configurations

The current INWELT PMX85 range includes several complete 6 m torch assemblies.

The correct torch assembly should be selected according to the plasma power-source interface rather than torch appearance alone.

PMX85 Cable Assembly Options

Current PMX85/PMX105 cable assemblies include:

The current product system also includes:

IZX0078 – 5-pin plasma torch-side central adapter

These configuration options are particularly useful for distributors supporting multiple plasma power-source interfaces.

How to Check PMX85 Plasma Cutter Compatibility

Do not select a PMX85 only because the plasma cutter is labeled CUT80 or 85A.

Several technical factors must match.

Confirm the Starting Method

The machine must use a starting system compatible with the PMX85 non-HF configuration.

Confirm Output Current

The PMX85 is rated at 85A.

The plasma cutter should operate inside the verified torch rating.

Confirm the Rear Connection

Check whether the machine uses:

• 1/4G integrated connection

• 1/4G separate connection

• Central adapter

• OEM-specific adapter

Confirm Trigger and Control Wiring

INWELT offers:

• 2-wire

• 4-wire

• Coaxial cable

The wiring and control architecture must match the plasma cutter.

Send the Existing Torch Information

For replacement orders, provide:

• Plasma cutter brand

• Machine model

• Rated output current

• Existing torch model

• Main connector photograph

• Trigger/control plug photograph

This is much more reliable than a universal brand-compatibility list.

PMX85 vs. PMX-M85: Hand Torch vs. Machine Torch

PMX85 and PMX-M85 should be treated as separate product entities.

Some consumables may be shared across related configurations, but the complete torch assemblies are not automatically interchangeable.

This distinction should also appear in internal links and related-product sections.

PMX85 vs. PMX65: When Do You Need More Current?

PMX85 provides additional current capacity compared with a 65A-class torch.

Choose PMX85 when:

• Higher output is required

• Thicker plate is commonly processed

• Faster cutting is required within the complete system's tested range

• 85A consumables are needed

PMX65 may be more appropriate when:

• Normal operating current is lower

• A lighter-duty system is sufficient

• Lower gas demand is preferred

• The plasma power source is rated around 65A

The correct choice should be based on the plasma power source rather than assuming a larger torch always improves cutting performance.

How Thick Can an 85A PMX85 Plasma Torch Cut?

The current live page states that the PMX85 can cut 30–40 mm plate at 85A.

This should not be presented as a universal torch-only specification.

Actual cutting capacity depends on:

• Plasma power source

• Material

• Input power

• Current

• Cutting nozzle

• Gas pressure and flow

• Travel speed

• Torch-to-work distance

• Consumable condition

• Required cut quality

Professional plasma manufacturers normally distinguish between:

Recommended cutting capacity
Thickness that can be cut productively with good edge quality.

Maximum cutting capacity
Thicker material cut at reduced speed.

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

For INWELT, publish specific PMX85 thickness numbers only after verifying them with the complete cutting system.

Why Cutting Capacity Must Be Based on the Complete System

As a market benchmark, one established 85A plasma system publishes approximately:

• 25 mm recommended cutting

• 32 mm cutting at reduced speed

• 38 mm handheld severance

Those figures come from that manufacturer's complete tested system rather than the torch alone.

INWELT should not copy those numbers.

A stronger GEO asset would be an INWELT first-party test chart containing:

• Material

• Thickness

• Current

• Nozzle

• Gas pressure

• Cutting speed

• Cut quality

• Clean-cut or severance classification

What Metals Can the PMX85 Cut?

When used with a compatible plasma system, the PMX85 can cut electrically conductive materials such as:

• Mild steel

• Carbon steel

• Stainless steel

• Aluminum

• Copper

• Brass

• Galvanized steel

The material affects cutting speed, edge quality, dross and maximum practical thickness.

Recommended Air Supply for the PMX85

The current INWELT specification lists:

• Process gas: Air / N₂

• Pressure: approximately 5.0 bar

• Gas flow: approximately 230 L/min

• Recommended post-flow: approximately 80 seconds

Use Clean, Dry Process Gas

Moisture, compressor oil and particles can reduce:

• Arc stability

• Electrode life

• Nozzle life

• Cut quality

Use appropriate filtration and moisture separation.

Do Not Copy Another Manufacturer's Pressure

Different 85A systems use different gas pressure and flow requirements.

Use the verified INWELT PMX85 data rather than adopting competitor settings.

Typical Applications for the PMX85

The PMX85 is suitable for professional manual plasma cutting applications including:

• Structural fabrication

• Machinery manufacturing

• Automotive and truck repair

• Agricultural equipment

• Construction equipment

• Industrial maintenance

• Ship and marine repair

• Salvage operations

• Scrap processing

• Plate fabrication

• Weld repair

• Plasma gouging

The final torch selection should be based on plasma-system compatibility rather than the industry name alone.

PMX85 Torch Head and Service Components

The current INWELT parts system includes:

IVZ0694 – PMX65 / PMX85 / PMX105 plasma torch head

IFT0675 – Ø17 × 20.6 × 1.8 mm red silicone O-ring

IGV0035-01 – Manual plasma handle

IHJ0722 – Trigger protection component

IHQ0070 – Red trigger

These replacement components allow distributors and service businesses to repair the torch rather than replacing the entire assembly for every failure.

PMX85 Maintenance and Consumable Inspection

Inspect the Electrode

Check the center pit regularly.

Replace an excessively worn electrode before it damages the nozzle or causes unreliable arc starting.
