INWELT WP9 110A Gas-Cooled TIG Welding Torch

Compact Gas-Cooled TIG Torch for Precision GTAW Welding

The INWELT WP9 TIG Welding Torch is a compact gas-cooled torch designed for precision GTAW/TIG welding where lightweight handling, accurate torch control and access to confined joints are important.

The INWELT WP9 configuration is rated at 110A DC and 95A AC at a 35% duty cycle and supports tungsten electrodes from Ø0.5 mm to Ø1.6 mm. Standard cable lengths of 4 m and 8 m are available for different welding stations and working ranges.

Its compact torch head makes the WP9 particularly suitable for precision fabrication, thin-section welding, repair work and applications where a larger TIG torch can be difficult to position.

INWELT also offers rigid and flexible-head configurations, multiple switch-control options, cable assemblies and OEM/private-label solutions for welding equipment manufacturers, distributors, importers and wholesalers.

INWELT WP9 TIG Welding Torch Technical Specifications

Torch connection, switch configuration and cable assembly should be confirmed according to the TIG welding machine before ordering.

Why Choose the INWELT WP9 Gas-Cooled TIG Torch?

The WP9 is designed for applications where torch size and control are often more important than very high amperage capacity.

Compact Torch Head for Better Joint Access

The small WP9 torch head makes it easier to position the tungsten electrode around:

• Tight corners

• Tubes and pipes

• Small fabricated assemblies

• Internal joints

• Thin sheet components

• Restricted-access welds

This makes the WP9 particularly useful for precision TIG welding where a larger torch may limit visibility or torch movement.

Lightweight Design for Precise Torch Control

A compact TIG torch can reduce the amount of weight the operator must control at the welding joint.

The WP9 design helps provide precise manipulation of:

• Torch angle

• Arc length

• Travel speed

• Filler-wire position

• Tungsten-to-work distance

These factors are especially important when producing small, controlled TIG welds.

Gas-Cooled Construction

The WP9 is gas cooled and does not require a separate water-cooling unit.

This simplifies the torch assembly and makes it suitable for lower- to medium-current TIG applications where the INWELT WP9 amperage and duty-cycle ratings are sufficient.

For applications requiring significantly higher amperage or longer continuous arc-on time, a higher-capacity air-cooled or water-cooled TIG torch may be more appropriate.

WP9 and WP9F TIG Torch Configurations

Different welding applications require different torch-head geometries.

INWELT can supply both rigid and flexible versions of the WP9 platform.

WP9 Rigid-Head TIG Torch

The standard rigid-head configuration provides a fixed torch-neck position.

It is suitable for general TIG welding where:

• Joint access is straightforward

• A fixed torch angle is preferred

• Torch durability and simplicity are priorities

• Frequent neck repositioning is unnecessary

The rigid version is a practical choice for general fabrication and repeatable welding tasks.

WP9F Flexible-Head TIG Torch

The WP9F flexible-head TIG torch provides additional positioning flexibility for confined or awkward welding joints.

The flexible head allows the operator to position the torch more conveniently according to the geometry of the workpiece.

Typical uses include:

• Pipe joints

• Corners

• Restricted assemblies

• Automotive components

• Small fabrication

• Maintenance welding

• Complex joint geometry

Avoid repeatedly bending a flexible torch head beyond its intended operating range, as excessive flexing can shorten torch-head service life.

4 m and 8 m WP9 TIG Torch Cable Options

INWELT supplies WP9 torch assemblies with 4 m and 8 m cable lengths.

4 m Cable Assembly

A 4 m cable is suitable for compact welding stations where the operator works relatively close to the TIG power source.

Potential advantages include:

• Less cable weight

• Reduced cable drag

• Easier storage

• Cleaner workstation layout

• Easier torch manipulation

8 m Cable Assembly

An 8 m assembly provides additional working range when the welding machine cannot be positioned close to the workpiece.

It can be useful for:

• Large fabrication areas

• Vehicle repair

• Maintenance work

• Large assemblies

• Fixed welding-machine installations

Longer cables can add weight and handling resistance, so cable length should be selected according to the actual working distance rather than simply choosing the longest available option.

Tungsten Electrode Compatibility for the WP9 TIG Torch

The INWELT WP9 configuration supports tungsten electrodes from Ø0.5 mm to Ø1.6 mm.

The correct tungsten diameter should be selected according to:

• Welding current

• AC or DC welding

• Base material

• Joint type

• Welding-machine settings

• Tungsten electrode type

Common tungsten electrode components within a WP9 torch assembly include:

• Tungsten electrode

• Collet

• Collet body or gas lens

• Ceramic cup

• Back cap

• Insulator

• Torch body

Always match the collet and related consumables to the selected tungsten diameter.

Using mismatched consumables can affect tungsten clamping, shielding-gas distribution and arc stability.

Standard Collet Body vs. Gas Lens Setup

The WP9 can be configured with different front-end consumable systems according to application requirements.

Standard Collet Body

A conventional collet-body setup provides a simple and economical shielding-gas arrangement for general TIG welding.

It is suitable for many common workshop applications where extended tungsten stick-out is not required.

Gas Lens Setup

A compatible gas lens helps distribute shielding gas more evenly around the tungsten electrode.

Depending on the welding application, a gas lens can help provide:

• Smoother shielding-gas coverage

• Improved weld-pool protection

• Greater allowable tungsten extension

• Better access to certain recessed joints

Gas-lens performance still depends on cup size, gas flow, tungsten extension, torch angle and surrounding airflow.

What Materials Can Be Welded with a WP9 TIG Torch?

When connected to a suitable TIG welding power source and configured with the correct tungsten, shielding gas and filler material, the WP9 can be used for welding common materials including:

• Stainless steel

• Carbon steel

• Mild steel

• Aluminum

• Nickel alloys

• Copper alloys

• Titanium and other suitable GTAW materials

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

Material compatibility also depends on:

• AC/DC capability of the welding machine

• Shielding gas

• Tungsten selection

• Filler metal

• Welding procedure

• Joint design

• Required welding current

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

Typical Applications for the WP9 TIG Welding Torch

The compact WP9 platform is well suited to precision TIG welding environments.

Typical applications include:

• Precision metal fabrication

• Stainless-steel fabrication

• Tube and pipe welding

• Automotive repair and fabrication

• Motorsport components

• Thin-sheet fabrication

• Instrumentation components

• Maintenance and repair

• Small machinery components

• Artistic metalwork

• Prototype fabrication

• Restricted-access welding

The appropriate torch should always be selected according to welding current, duty cycle and access requirements.

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

WP9 and WP17 are both widely used gas-cooled TIG torch formats, but they are designed for different priorities.

Choose WP9 When:

• Compact torch size is important

• Welding current is within WP9 specifications

• Tight joint access is required

• Precision torch manipulation is important

• Thin or small components are being welded

Consider WP17 When:

• Higher welding current is required

• Longer arc-on time is expected

Poor Shielding Gas Coverage

Check:

• Gas flow

• Ceramic cup

• Gas lens or collet body

• Torch O-rings and seals

• Gas hose

• Excessive tungsten extension

• Drafts around the weld

Gas flow should be adjusted according to cup size and welding conditions rather than simply increased to the maximum.

Tungsten Will Not Stay Tight

Inspect the collet, collet body and back-cap assembly.

Make sure that all components match the tungsten diameter being used.

Unstable TIG Arc

Check:

• Tungsten condition

• Ground connection

• Torch electrical connection
