MB 15 X 150Amp MIG TORCH 3mtr, 4mtr, 5mtr

Here is a detailed description of the MB 15 (also commonly known as the 15AK) MIG torch, which is available in 3-meter, 4-meter, and 5-meter lengths.

Description: MB 15 / 15AK MIG/MAG Welding Torch
The MB 15 (or 15AK) is one of the most common and versatile MIG/MAG welding torches on the market. It is an air-cooled torch designed for light to medium-duty welding applications. Its popularity stems from its lightweight design, robust construction, and the wide availability of inexpensive consumables.


It is a "standard" in the industry, meaning that consumables (tips, nozzles, etc.) are interchangeable between many different brands that produce an "MB 15" style torch.

Key Specifications
Here are the typical technical details for this torch:

Model: MB 15 / 15AK

Cooling Type: Air-Cooled

Welding Process: MIG (GMAW) / MAG

Duty Cycle Rating:

≈150 Amps @ 60% Duty Cycle (using Mixed Gas, e.g., Argon/CO
2)

≈180 Amps @ 60% Duty Cycle (using 100% CO2 gas)

Compatible Wire Diameter: 0.6 mm to 1.0 mm (0.023" to 0.035")

Gas Flow: 10 - 18 L/min

Connection Type: Almost always features a standard Euro Connector for quick and easy connection to the welding machine.

Features by Length
The different lengths you mentioned (3m, 4m, 5m) do not change the torch's ampacity or performance, only its reach and operator comfort.

3 meters (approx. 10 ft):

Common Use: This is the most common length, often supplied as standard with many compact and workshop MIG welders.

Advantages: Lighter weight, less cable to manage, ideal for benchtop work or when the welder is close by.

Disadvantages: Limited reach.

4 meters (approx. 13 ft):

Common Use: A popular upgrade that offers a noticeable improvement in reach.

Advantages: Provides more flexibility to move around a workpiece (e.g., automotive repair, small fabrication) without moving the welder itself.

Disadvantages: Slightly heavier than the 3m version.

5 meters (approx. 16 ft):

Common Use: Used in fabrication shops where the workpiece is large or the welder is stationary.

Advantages: Maximum reach for this torch class, allowing the operator significant freedom of movement.

Disadvantages: Can be more cumbersome. At this length, minor wire feed issues (like liner friction) can become more noticeable if not properly maintained.

Common Applications
The MB 15 is the standard torch for:

Auto Body Repair: Its size is perfect for sheet metal and frame work.

Light Fabrication: Ideal for building gates, trailers, and brackets.

Maintenance & Repair: A versatile "go-to" torch for general repairs.

Hobbyist & DIY: The most common torch found on pro-sumer and high-end hobbyist welders.

Standard Consumables (Replacement Parts)
Contact Tip: M6 thread (sized to your wire, e.g., 0.8 mm or 0.9 mm)

Gas Nozzle: Typically conical (push-on style)

Tip Holder / Gas Diffuser: Holds the contact tip and distributes the shielding gas.

Swan Neck: The curved metal tube at the end of the torch.

Liner: The steel coil (for solid wire) or Teflon (for aluminum) that guides the wire through the cable.
