Portable MIG welding machines for total control anywhere
The Master M 205 and the Master M 323 set 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 and Master M 323 are also easy to use. Both portable MIG welding machines come with Weld Assist, which offers automatic parameter settings that 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, 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 programs for pulse MIG and 20 programs for 1-MIG.
The Master M 323 is a high-performance portable MIG welding machine that delivers 320 amps of power at a 40% duty cycle. It's a portable and light small MIG welder ready for big jobs anywhere on site. Improve welding quality and save time with 28 built-in welding programs for Fe, Ss, AlMg5, AlSi5, CuSi3, CuAl8, and FC-CrNiMo filler materials. In addition, the Master M 323 portable MIG welder includes 4 welding programs for the MAX Cool arc welding process.
If you're looking for a portable MIG welder that can complete high-quality welds in challenging environments, the Master M 205 and Master M 323 should be on top of your list.
Invest in work site safety and ergonomics
Master M 205 and 323 are equipped with self-charging LED work lights for better safety and convenience. Use with or without mains power connected, and improve safety in low light conditions. In addition, both models are safe to lift from the handle by a crane. Lightweight models are easy to carry and enable working in tight spaces.
