INWELT supplies MIG welding torch consumables and replacement parts for MIG/MAG welding systems, including contact tips, gas nozzles, gas diffusers, liners and model-specific torch accessories.
Our current range includes consumables for PANA-style, Tweco-style, 15AK, 24KD, 36KD, 501D and MB-series MIG torch configurations, with options for different wire diameters, torch models, front-end assemblies and welding applications.
For equipment manufacturers, distributors, importers, wholesalers and industrial welding users, INWELT provides individual replacement parts, consumable combinations and OEM/ODM supply solutions based on confirmed torch specifications.
MIG torch consumables are the replaceable components located around the front end of a MIG/MAG welding torch. They directly influence electrical current transfer, wire feeding, shielding gas coverage and torch maintenance.
INWELT's MIG welding accessory range includes:
| Consumable | Main Function | Key Selection Factors |
|---|---|---|
| Contact Tip | Transfers welding current to the wire | Wire diameter, thread, length, material |
| Gas Nozzle | Directs shielding gas toward the weld area | Torch series, mounting method, bore, geometry |
| Gas Diffuser | Distributes shielding gas and supports the front-end assembly | Torch model, thread, tip-holder system |
| Tip Holder / Adapter | Connects and positions the contact tip | Torch neck and contact-tip specification |
| MIG Torch Liner | Guides welding wire through the cable assembly | Wire diameter, wire material, cable length |
| Insulator / Spatter Protection | Provides separation and protects front-end components | Torch and nozzle configuration |
| Consumable Kit | Combines commonly replaced torch components | Torch model and application |
The correct combination should always be confirmed according to the complete torch configuration rather than selecting a replacement part by appearance alone.
The contact tip transfers welding current to the continuously fed welding wire and guides the wire into the arc zone.
INWELT supplies MIG contact tips in different copper-alloy configurations, including E-Cu and CuCrZr options for selected torch systems.
Contact tips can be supplied for different wire diameters and torch platforms. The correct selection should consider:
Welding wire diameter
Contact-tip thread
Contact-tip length
Torch model
Welding current
Wire material
Welding process
A contact tip should match the welding wire diameter and the corresponding torch front-end assembly. A correct wire diameter alone does not guarantee compatibility because thread, length and tip-holder design must also match.
The gas nozzle directs shielding gas around the contact tip and weld zone.
INWELT MIG welding nozzles are available in different shapes, dimensions and material configurations according to the torch series and application.
Current product configurations include PANA-style nozzles for P180, P350 and P500 torch platforms as well as Tweco-style heavy-duty nozzle configurations such as 23H62.
Nozzle selection should consider:
Torch series
Nozzle mounting method
Bore diameter
Nozzle length
Contact-tip position
Welding application
Required gas coverage
Common nozzle geometries may include conical, cylindrical or tapered designs depending on the torch system.
Inspect the nozzle regularly for excessive spatter, deformation, heat damage, blocked gas passages or damaged threads.
MIG gas diffusers and contact-tip holders are important parts of the torch front-end assembly.
The diffuser connects the gas path with the front-end consumable system while supporting the contact tip or tip holder configuration. Different MIG torch platforms use different diffuser dimensions, threads and mounting structures.
INWELT currently supplies gas diffuser configurations including:
Tweco-style 54A copper gas diffuser
24KD / 36KD / 501D diffuser configurations
Model-specific diffuser and contact-tip systems for selected MIG torches
Material and construction vary by product configuration. Therefore, the correct diffuser should be selected according to the torch model and the corresponding contact-tip and nozzle system.
The MIG torch liner guides the welding wire through the torch cable assembly toward the contact tip.
Liner selection should be based on more than cable length. Important factors include:
Welding wire diameter
Wire material
Liner internal diameter
Torch cable length
Torch model
Front-end termination
Rear connector configuration
Steel, stainless steel and aluminum welding may require different liner configurations depending on the welding wire and feeding system.
A worn, contaminated or incorrectly selected liner can contribute to:
Irregular wire feeding
Increased feeding resistance
Bird-nesting
Burnback
Arc instability
Premature contact-tip wear
For replacement projects, confirm the existing torch model, liner specification and cable length before ordering.
Selecting consumables by torch family provides a more reliable way to identify replacement parts.
INWELT supplies PANA-style consumables for P180, P350 and P500 MIG torch configurations.
Available product types include:
MIG contact tips
Gas nozzles
Front-end replacement components
Contact-tip selection should be matched to the specific PANA torch platform, wire diameter and required material configuration.
INWELT supplies selected Tweco-style MIG consumables, including:
54A gas diffusers
23H62 heavy-duty gas nozzles
Related contact-tip and front-end configurations
For replacement applications, confirm the torch model, diffuser configuration and nozzle mounting method before ordering.
The 15AK, 24KD and 36KD families are common MIG torch consumable formats.
INWELT supplies selected contact tips and replacement components for these configurations, including consumable options based on wire diameter and torch assembly.
INWELT supplies model-specific gas diffuser configurations for 24KD, 36KD and 501D MIG torch systems.
The diffuser should be matched with the correct contact tip, nozzle and torch neck configuration.
INWELT also supplies replacement consumables and spare parts for selected MB-style MIG torch configurations, including MB15, MB24, MB25, MB36 and MB501D.
Depending on the torch model, replacement components may include:
Contact tips
Gas nozzles
Diffusers
Tip holders
Liners
Insulators
Related front-end components
Exact compatibility should be confirmed by torch model, part number or technical drawing.
Correct consumable selection starts with identifying the complete torch configuration.
Start with the torch model or consumable family.
Examples include:
P180
P350
P500
15AK
24KD
36KD
501D
MB15
MB24
MB25
MB36
MB501D
Tweco-style configurations
If the model is unknown, provide a clear photo of the torch neck and existing consumable assembly.
The contact-tip bore must correspond to the welding wire diameter.
Common MIG wire sizes include 0.8 mm, 1.0 mm, 1.2 mm and 1.6 mm, while larger or smaller sizes may be available for specific applications.
Do not select a contact tip only by visual appearance. Confirm the marked wire size and the corresponding torch specification.
Two contact tips with the same wire diameter may still be incompatible if their thread, length or seating dimensions are different.
Confirm:
Thread size
Overall length
Tip diameter
Tip-holder configuration
Torch series
The nozzle and diffuser form a connected front-end system.
Before ordering, check:
Nozzle mounting method
Diffuser thread
Nozzle bore
Contact-tip position
Torch neck configuration
A nozzle that physically fits the torch may still be incorrect if the diffuser or contact-tip relationship is different.
For liners, confirm:
Wire diameter
Wire material
Cable length
Liner material
Rear termination
Front termination
Torch model
For aluminum or other soft wires, liner selection should be made together with the complete wire-feeding system.
Consumables for manual welding and automated or robotic welding may have different requirements.
For robotic applications, repeatability of the contact tip, nozzle, diffuser, liner and front-end assembly is particularly important because consumable changes can affect production uptime and maintenance procedures.
Different MIG consumables can use different materials depending on the component and application.
E-Cu is commonly used for MIG contact tips where electrical conductivity and general-purpose performance are required.
CuCrZr copper alloy contact tips are available for selected INWELT torch configurations where greater thermal resistance is required.
The appropriate contact-tip material should be selected according to welding current, duty cycle, wire type and torch configuration.
MIG nozzles may be available in copper or brass configurations depending on the product series and application.
The material, geometry and mounting method should be confirmed against the specific torch system.
MIG torch consumables should be inspected according to actual welding conditions rather than a fixed universal replacement interval.
Common signs that a consumable requires inspection or replacement include:
Enlarged or damaged contact-tip bore
Irregular wire feeding
Unstable arc starts
Excessive spatter
Blocked gas nozzle
Deformed nozzle
Damaged diffuser
Burnback around the contact tip
Increased feeding resistance
Damaged or contaminated liner
Regular inspection helps identify consumable wear before it develops into a larger wire-feeding or shielding-gas problem.

MIG welding consumables are replaceable components used with MIG/MAG welding torches. Common examples include contact tips, gas nozzles, gas diffusers, liners, tip holders, insulators and related replacement parts.
A contact tip transfers welding current to the welding wire while guiding the wire into the arc zone. The contact-tip bore must be matched to the welding wire diameter.
The gas nozzle directs shielding gas around the welding arc and weld pool. Its geometry, bore and mounting configuration must match the torch front-end assembly.
A gas diffuser distributes shielding gas through the torch front end and supports the contact-tip assembly. Different MIG torch series use different diffuser configurations.
Confirm the torch model, contact-tip family, wire diameter, thread, length and material. Do not select a contact tip based only on wire diameter.
Match the liner to the torch model, cable length, welding wire diameter, wire material and liner termination configuration.
Not necessarily. Similar-looking consumables may have different threads, lengths, mounting methods or front-end dimensions. Compatibility should be confirmed by model, part number, drawing or sample.
