Why we love the Kemppi Master M 205 Pulse MIG Welder
The Master M 205 sets new standards for power and performance in a portable MIG welding machine. With a portable, lightweight design that's easy to carry, you'll enjoy having a portable MIG welder that can be moved wherever you need it. If you're working in tight spaces, the 5" LCD screen is bright and easy to read, while self-charging LED lights can be turned on to improve safety. They work with or without mains power.
The Master M 205 is also easy to use. These portable MIG welding machines come with Weld Assist, which automatically sets parameters to help you start welding quickly. It's a simple solution that welders can also use with minimal experience. Just select the material thickness, joint type, and welding position, and start welding.
The Master M 205 is a portable pulse MIG welder with 200 amps of power at a 40% duty cycle. Take on a wider range of materials with pulse welding and do your best work anywhere with the convenience of a 1-phase power supply. Save time and take welding to the next level with 37 built-in MIG/MAG welding programs for Fe, Ss, AlMg5, AlSi5, CuSi3, and CuAl8 filler materials. The Master M 205 comes with 17 pulse-MIG programs and 20 1-MIG programs.
If you're looking for a portable MIG welder that can complete high-quality welds in challenging environments, the Master M 205 should be at the top of your list
