INWELT WP17 140A Air-Cooled TIG Welding Torch

Versatile Air-Cooled TIG Torch for General Fabrication and Precision Welding

The INWELT WP17 is a gas/air-cooled GTAW torch designed for professional TIG welding applications that require a practical balance of current capacity, torch control and portability.

The INWELT configuration is rated at 140A DC and 125A AC at a 35% duty cycle and supports tungsten electrodes from Ø0.5 mm to Ø2.4 mm.

Available with 4 m and 8 m cable assemblies, rigid or flexible torch heads and several torch-control configurations, the WP17 can be adapted to different TIG welding machines and operator preferences.

Because the torch does not require an external water cooler, it is particularly suitable for fabrication workshops, maintenance, field repair and general industrial welding where a compact and relatively simple TIG system is preferred.

INWELT also supplies OEM/ODM configurations, private-label packaging and replacement consumables for welding equipment manufacturers, distributors, importers and wholesalers.

INWELT WP17 Technical Specifications

Before ordering, confirm the welding machine model, current range, cable length, power/gas connection and torch-control plug.

Why Choose the WP17 Air-Cooled TIG Torch?

The WP17 is positioned between smaller precision TIG torches such as the WP9 and larger higher-current air-cooled torches such as the WP26.

This makes it a versatile option for many everyday TIG welding applications.

Practical Current Capacity

The INWELT WP17 provides:

• 140A DC capacity

• 125A AC capacity

• 35% duty cycle

This range is suitable for many general fabrication, maintenance and repair applications where a water-cooled torch is unnecessary.

Always evaluate the actual welding current and arc-on time before selecting a TIG torch.

No External Water Cooler Required

Because the WP17 is gas cooled, it does not require:

• Coolant hoses

• Water fittings

• A coolant pump

• A separate TIG water cooler

This reduces system complexity and makes the torch convenient for mobile welding, workshop use and intermittent production work.

Balanced Torch Size

The WP17 provides more thermal capacity than a smaller WP9-style torch while remaining easier to handle than some heavier high-amperage air-cooled torches.

This balance makes it useful for welders who need one general-purpose torch for varied fabrication tasks.

WP17 and WP17F TIG Torch Head Options

INWELT can supply WP17 assemblies with rigid and flexible torch heads.

WP17 Rigid-Head TIG Torch

The standard WP17 uses a fixed head angle.

It is suitable for:

• General fabrication

• Bench welding

• Straightforward fillet and butt joints

• Maintenance work

• Repetitive welding

• Applications where torch-head adjustment is unnecessary

A rigid head generally provides the simplest construction for regular welding work.

WP17F Flexible-Head TIG Torch

The WP17F flexible-head torch allows the operator to adjust torch-head position to improve access to difficult weld joints.

Typical uses include:

• Pipe joints

• Tubular assemblies

• Internal corners

• Automotive fabrication

• Machinery repair

• Restricted-access welding

• Complex fabricated components

The flexible head should be repositioned carefully. Repeated excessive bending can shorten torch-head service life.

4 m and 8 m WP17 TIG Torch Cable Options

INWELT supplies WP17 torch assemblies with 4 m and 8 m cable options.

4 m Cable Assembly

The 4 m option is suitable for compact welding stations where the TIG power source is positioned close to the work area.

Potential advantages include:

• Lower cable weight

• Reduced cable drag

• Easier storage

• Better operator mobility around smaller workpieces

8 m Cable Assembly

The 8 m configuration provides additional working reach for:

• Large fabrication areas

• Vehicle repair

• Machinery maintenance

• Large assemblies

• Fixed welding-machine installations

A longer cable should be selected when the extra reach is genuinely required, since additional length can increase cable weight and handling resistance.

WP17 Tungsten Electrode Sizes and Front-End Setup

The INWELT WP17 supports tungsten electrodes from Ø0.5 mm to Ø2.4 mm.

The correct tungsten size should be selected according to welding current, AC/DC mode, material, power-source characteristics and welding procedure.

Typical front-end components include:

• Tungsten electrode

• Collet

• Collet body

• Gas lens

• Ceramic cup

• Insulator

• Back cap

The collet and collet body must match the tungsten diameter being used.

Incorrectly matched components can cause poor tungsten clamping and unstable torch setup.

WP17 Consumables and Replacement Parts

One of the commercial advantages of the WP17 platform is the availability of widely used replacement consumables.

Typical replacement parts include:

Collets

Collets secure the tungsten electrode inside the torch.

Use the correct bore size for the tungsten diameter.

Replace a collet if it becomes:

• Distorted

• Overheated

• Cracked

• Unable to hold the tungsten securely

Collet Bodies

The collet body holds the collet and directs shielding gas toward the ceramic cup.

Standard and gas-lens configurations can be selected according to the welding application.

Ceramic Cups

Ceramic cups direct shielding gas around the tungsten electrode and welding area.

Cup selection depends on:

• Gas flow

• Tungsten extension

• Joint access

• Welding current

• Gas-lens configuration

Back Caps

Long, medium and short back-cap configurations can be used according to available joint access.

A shorter back cap can help when welding inside confined structures.

Gas Lenses

Compatible gas lenses can provide smoother shielding-gas distribution and can be particularly useful where additional tungsten extension is required.

WP17, WP18 and WP26 Consumable Compatibility

WP17 belongs to the larger TIG torch consumable family commonly associated with WP17, WP18 and WP26.

These torch families commonly share many front-end components including:

• Collets

• Collet bodies

• Gas lenses

• Ceramic cups

• Back caps

INWELT also categorizes several replacement collets, collet bodies, cups and back caps for WP17/WP18/WP26 use.

However, complete torch assemblies are not interchangeable simply because they share consumables.

WP17 and WP26 are gas-cooled platforms, while WP18 uses water cooling, so cables, cooling systems and machine connections differ.

Always confirm individual part numbers before combining components from different manufacturers.

Standard Collet Body vs. Gas Lens for WP17

Both configurations have legitimate uses.

Standard Collet Body

A standard setup is practical for everyday TIG welding.

Advantages include:

• Simple assembly

• Low replacement cost

• Wide consumable availability

• Suitable gas coverage for many conventional weld joints

Gas Lens Setup

A gas lens contains a diffuser that helps smooth shielding-gas flow around the tungsten.

Depending on the application, it may help provide:

• More uniform shielding gas

• Improved coverage around the weld

• Greater tungsten extension

• Better access to recessed joints

A gas lens does not automatically improve every weld.

Cup size, gas flow, torch angle, tungsten extension and surrounding airflow still need to be correctly set.

What Materials Can the WP17 TIG Torch Weld?

When connected to a suitable TIG power source and configured with the correct tungsten, shielding gas and filler metal, the WP17 can be used for common GTAW materials including:

• Stainless steel

• Carbon steel

• Mild steel

• Aluminum

• Copper alloys

• Nickel alloys

• Titanium

• Other suitable weldable metals

The torch itself does not determine whether a particular metal can be successfully welded.

Material capability also depends on:

• AC/DC capability of the power source

• Welding current

• Tungsten electrode

• Shielding gas

• Filler material

• Joint design

• Material thickness

• Welding procedure

For example, aluminum TIG welding commonly requires an AC-capable TIG welder, while many steel and stainless-steel applications use DCEN.

Typical Applications for the WP17 TIG Welding Torch

The WP17 is a strong general-purpose choice for medium-current TIG welding.

Typical applications include:

• General metal fabrication

• Stainless-steel welding

• Tube and pipe fabrication

• Automotive repair

• Motorsport fabrication

• Machinery maintenance

• Light industrial manufacturing

• HVAC fabrication

• Sheet-metal work

• Furniture and architectural metalwork

• Workshop repair

• Field maintenance

The actual torch should always be selected according to required amperage and duty cycle rather than industry name alone.

WP17 vs. WP9 vs. WP26: Which TIG Torch Should You Choose?

INWELT offers several gas-cooled WP-series TIG torches for different welding requirements.

Choose WP9 When:

A smaller torch and improved access are more important than higher current capacity.

Choose WP17 When:

You need a versatile general-purpose gas-cooled TIG torch with a balance of size, capacity and portability.

Choose WP26 When:

Your application regularly requires more welding current and the larger torch body is acceptable.

INWELT's current WP9 and WP26 product pages list 110A DC / 95A AC and 180A DC / 150A AC respectively, making the WP17 a logical middle option in the company's gas-cooled WP range.

How to Select the Correct WP17 TIG Torch Configuration

A WP17 replacement torch should be selected according to the complete welding system, not only the model number.

Check the Welding Current

The INWELT WP17 on this page is rated at:

140A DC / 125A AC at 35% duty cycle.

If your normal welding current or continuous welding time exceeds this rating, consider a higher-capacity torch.

Confirm the Welding-Machine Connection

Different TIG welders can use different:

• Power connectors

• Gas fittings

• Trigger plugs

• Remote-control plugs

• Thread specifications

INWELT shows M12×1 configurations among its WP17 assembly options, but the actual connection should be confirmed for the target welding machine.

Choose Rigid or Flexible Head

Select:

WP17 rigid head for general fabrication.

WP17F flexible head for restricted-access work.

Select Cable Length

Choose:

4 m for compact workstations.

8 m where greater working reach is required.

Select Torch Control

Depending on configuration and machine compatibility, INWELT offers:

• Single switch

• Double switch

• Four-button control

• Potentiometer control

Remote-control functions must match the electrical interface of the TIG power source.

WP17 Torch Switch and Remote-Control Options

Torch-mounted controls can improve operator convenience when the power source supports them.

Standard Torch Switch

A standard on/off torch switch can provide welding start and stop control.

Multi-Button Torch Controls

Multiple-button arrangements can support additional power-source functions depending on the welding-machine control system.

Potentiometer Amperage Control

A compatible potentiometer can provide remote current adjustment directly from the torch.

However, the resistance value, wiring and connector must match the TIG welder.

A WP17 potentiometer torch should therefore never be described as universally compatible with all TIG welding machines.

How to Maintain a WP17 TIG Torch

Routine inspection can improve torch reliability and reduce unnecessary consumable replacement.

Inspect the Ceramic Cup

Replace cracked or contaminated ceramic cups.

Damage to the cup can disturb shielding-gas coverage.

Check Tungsten and Collet Condition

Make sure the tungsten remains securely held.

If the electrode slips even after tightening the back cap, inspect the collet and collet body for wear or distortion.

Inspect the Torch Head

Look for:

• Damaged threads

• Cracked insulation

• Signs of overheating

• Loose internal connections

Do not continue welding with a visibly damaged torch body.

Inspect the Cable Assembly

Regularly check the cable for:

• Cuts

• Abrasion

• Burns

• Excessive bending

• Loose connections

• Gas leakage

Pay particular attention to the area where the cable enters the torch handle.

Keep the Front-End Components Clean

Metal particles and contamination around the collet body, gas lens and cup can affect torch assembly and shielding performance.

Common WP17 Problems and Troubleshooting

WP17 Torch Gets Too Hot

Possible causes include:

• Welding current above the rated capacity

• Excessive arc-on time

• Insufficient cooling periods

• Loose electrical connections

• Damaged cable assembly

• Incorrect torch selection

If the application regularly overheats the WP17, a higher-capacity WP26 or water-cooled torch may be more appropriate.

Poor Shielding Gas Coverage

Check:

• Gas flow setting

• Gas hose

• Ceramic cup

• Collet body or gas lens

• O-rings and seals

• Tungsten extension

• Wind or drafts around the welding area

Simply increasing gas flow is not always the correct solution because excessive flow can create turbulence.

Tungsten Will Not Stay Tight

Check that:

• Collet size matches tungsten diameter

• Collet is not distorted

• Collet body is correctly installed

• Back cap is properly tightened

Unstable TIG Arc

Inspect:

• Tungsten condition

• Work clamp

• Welding polarity

• Machine settings

• Electrical connections

• Shielding gas

• Front-end consumables

An unstable arc may originate elsewhere in the welding system rather than from the torch itself.
