MB15 / MB24 / MB25 / MB36 / MB501D MIG Torch Gas Nozzles

INWELT supplies MIG torch gas nozzles for MB15, MB24, MB25, MB36 and MB501D torch configurations. The range covers commonly used MB-series front-end nozzle sizes from Φ12 mm to Φ16 mm, with copper and CuCrZr material options available according to the required configuration.

MIG torch gas nozzles, also known as MIG torch shrouds, direct shielding gas around the welding arc and help maintain the required gas coverage between the torch front end and the weld area. Correct nozzle selection should be based on the torch model, nozzle dimensions, front-end configuration and welding application.

For distributors, welding equipment manufacturers and industrial buyers, INWELT provides bulk supply, OEM/ODM support and customized packaging options.

Material options include copper and CuCrZr according to the specified product configuration.

For repeat orders or OEM projects, buyers can provide the torch model, existing nozzle sample, reference number or technical drawing so the required configuration can be confirmed before production.

MB15 / 15AK MIG Torch Gas Nozzle

The MB15 gas nozzle is designed for the MB15 / 15AK MIG torch configuration.

Standard INWELT specification:

• Torch model: MB15 / 15AK

• Gas nozzle size: Φ12 mm

• Reference: 145.0075

• Application: MIG / MAG welding

• Material options: Copper / CuCrZr

• Supply: Wholesale, bulk and OEM

The MB15 nozzle is suitable for the compact 15AK front-end configuration. Keep the nozzle clean and free from excessive welding spatter to maintain an unobstructed shielding-gas path.

MB24 / 24KD MIG Torch Gas Nozzle

The MB24 gas nozzle is designed for the MB24 / 24KD MIG torch configuration.

Standard INWELT specification:

• Torch model: MB24 / 24KD

• Gas nozzle size: Φ12.5 mm

• Reference: 145.0080

• Application: MIG / MAG welding

• Material options: Copper / CuCrZr

• Supply: Wholesale, bulk and OEM

The nozzle works as part of the MB24 front-end consumable system and should be selected together with the corresponding torch head and front-end components.

MB25 / 25AK MIG Torch Gas Nozzle

The MB25 gas nozzle is designed for the MB25 / 25AK MIG torch configuration.

Standard INWELT specification:

• Torch model: MB25 / 25AK

• Gas nozzle size: Φ15 mm

• Reference: 145.0100

• Application: MIG / MAG welding

• Material options: Copper / CuCrZr

• Supply: Wholesale, bulk and OEM

The MB25 gas nozzle helps direct shielding gas around the welding arc. Inspect the nozzle regularly for dents, deformation or excessive spatter buildup that could affect gas coverage.

MB36 / 36KD MIG Torch Gas Nozzle

The MB36 gas nozzle is designed for the MB36 / 36KD MIG torch configuration.

Standard INWELT specification:

• Torch model: MB36 / 36KD

• Gas nozzle size: Φ16 mm

• Reference: 145.0078

• Application: MIG / MAG welding

• Material options: Copper / CuCrZr

• Supply: Wholesale, bulk and OEM

The MB36 is used with a larger front-end configuration than MB15 and MB24. Select the nozzle according to the specific torch head and consumable system rather than using nozzle size alone as the compatibility reference.

MB501D / 501D MIG Torch Gas Nozzle

The MB501D gas nozzle is designed for the 501D water-cooled MIG torch configuration.

Standard INWELT specification:

• Torch model: MB501D / 501D

• Gas nozzle size: Φ16 mm

• Reference: 145.0085

• Application: Heavy-duty MIG / MAG welding

• Material options: Copper / CuCrZr

• Supply: Wholesale, bulk and OEM

The MB501D uses a water-cooled torch configuration and a 501D torch head system. The gas nozzle should be matched with the corresponding front-end components when replacing individual consumables.

What Does a MIG Torch Gas Nozzle Do?

A MIG torch gas nozzle directs shielding gas from the torch front end toward the weld area.

Its main functions include:

• Directing shielding gas around the welding arc

• Supporting appropriate gas coverage around the weld pool

• Providing the required clearance around the contact tip

• Helping position the contact tip relative to the weld area

• Protecting the front-end components from the surrounding welding environment

Nozzle geometry and size can affect accessibility, gas coverage and the relationship between the nozzle and contact tip. Therefore, nozzle selection should be based on the actual torch configuration and welding application.

How to Choose the Correct MIG Torch Nozzle

Before ordering a replacement MIG torch nozzle, confirm the following information:

1. Confirm the Torch Model

Identify the exact torch configuration first:

• MB15 / 15AK

• MB24 / 24KD

• MB25 / 25AK

• MB36 / 36KD

• MB501D / 501D

Do not select a nozzle based only on the appearance of the old part.

2. Confirm the Nozzle Size

The current INWELT configurations include:

• Φ12 mm

• Φ12.5 mm

• Φ15 mm

• Φ16 mm

The correct size depends on the corresponding torch model and front-end configuration.

3. Check the Torch Head

The nozzle should be matched with the corresponding torch head and front-end consumable system.

For example:

• 15AK → MB15 configuration

• 24KD → MB24 configuration

• 25AK → MB25 configuration

• 36KD → MB36 configuration

• 501D → MB501D configuration

4. Confirm the Material

INWELT can provide copper and CuCrZr material options according to the required configuration.

Material selection should consider the torch configuration, welding current, thermal conditions and purchasing requirements.

5. Confirm the Reference Number

For repeat orders, the fastest way to reduce ordering errors is to provide the existing part reference, product drawing or sample.

INWELT can confirm the corresponding model and specification before bulk production.

Copper and CuCrZr MIG Torch Nozzles

Copper and CuCrZr are available as material options for selected INWELT MIG torch nozzle configurations.

The appropriate material should be confirmed according to the required torch model, application and purchasing specification.

For standard replacement orders, buyers should provide:

• Torch model

• Nozzle size

• Material requirement

• Reference number

• Required quantity

• Packaging requirement

For OEM projects, material and dimensional specifications can be reviewed before production.

MIG Torch Nozzle Maintenance

Regular nozzle inspection can help maintain consistent shielding-gas coverage and reduce unnecessary consumable replacement.

Remove Welding Spatter

Welding spatter can accumulate around the nozzle opening and reduce the available gas path.

Clean the nozzle regularly according to the welding process and operating conditions.

Check for Deformation

A dented or deformed nozzle can change the relationship between the nozzle, contact tip and weld area.

Replace the nozzle if physical damage affects the required front-end configuration.

Inspect the Nozzle Opening

Check for excessive buildup, blockage or contamination around the nozzle opening.

Check the Contact Tip Position

The contact tip and nozzle work together as part of the torch front-end system. If the tip position changes unexpectedly, inspect the contact tip, diffuser, torch head and nozzle together.

MIG Torch Nozzle Compatibility Guide

Correct compatibility should be confirmed through the complete front-end configuration rather than the model number alone.
