What is the difference between MB15, MB25 and MB36 MIG torches?

Choosing the right MIG torch is vital to get the highest quality welds from your welder. The torch directly affects weld quality, operator comfort and how reliably you can work at different amperage levels.

In this article, we’ll break down the key differences between Parweld MB15, MB25 and MB36 MIG torches, explain what each one is best suited for and help you decide which torch is right for your welding setup.

What Do MB15, MB25 and MB36 Mean?

The MB numbering system refers primarily to the current capacity (amperage rating) of the MIG torch. As the numbers increase, so does the torch’s ability to handle higher welding currents and heavier-duty applications.

In simple terms:

• MB15 – Light-duty MIG torch
• MB25 – Medium-duty MIG torch
• MB36 – Heavy-duty MIG torch

Each step up offers higher amperage handling, improved cooling and more robust construction.

Parweld MB15 MIG Torch – Lightweight & Easy to Handle

The Parweld MB15 MIG torch is designed for light-duty welding and is commonly supplied with smaller MIG machines.

Key Characteristics:

• Rated at 140 amps (depending on duty cycle and gas)
• Slim torch neck and lightweight cable
• Excellent manoeuvrability and control

Best For:

• Automotive repairs
• Light fabrication
• DIY and hobby welding
• Thin materials and short weld runs

Why Choose an MB15?

If comfort and ease of use are your priority, the MB15 is ideal. Its lightweight design reduces operator fatigue, making it perfect for detailed work and lower-amperage welding.

Parweld MB25 MIG Torch – Versatile All-Rounder

The Parweld MB25 MIG torch is one of the most popular choices for general workshop use. It offers a balance between power handling and usability.

Key Characteristics:

• Typically rated up to 184 amps (depending on duty cycle)
• More robust build than the MB15
• Improved heat resistance for longer welds

Best For:

• General fabrication
• Medium-thickness steel
• Workshop and trade use
• Longer welding sessions

Why Choose an MB25?

If you need a reliable torch that can handle a wide range of jobs, the MB25 is a great all-round solution. It's powerful enough for heavier work while still being comfortable to use for day-to-day welding.

Parweld MB36 MIG Torch – Built for Heavy‑Duty Welding

The Parweld MB36 MIG torch is designed for high‑amperage, industrial applications where durability and heat management are essential.

Key Characteristics:

• Typically rated up to 240 amps (depending on duty cycle)
• Thicker cable and reinforced torch neck
• Designed for sustained, high‑output welding

Best For:

• Heavy fabrication
• Structural steelwork
• Industrial and production environments
• Thick materials and long weld runs

Why Choose an MB36?

When welding at higher currents for extended periods, the MB36 offers the strength and cooling capacity needed to maintain performance and torch lifespan.

Which Parweld MIG Torch Is Right for You?

• Choose MB15 if you mainly weld thin materials or want maximum comfort and control.
• Choose MB25 if you need versatility for everyday workshop fabrication.
• Choose MB36 if you regularly weld thicker materials at higher amperages.
