Extra utility
Use for high energy Stick (MMA), plus basic DC TIG or even MIG/MAG.
Less is more
Compact and light in weight, and still offering quality welding and efficiency
Remote control option
When connected with a suitable Kemppi remote control, you can adjust the welding current at distance
Powerful, efficient, value
Master S series MMA power sources are designed for high-performance professional welding, offering compact, robust and portable MMA power solutions with optimum energy efficiency. A perfect partner for heavy-duty MMA welding where the ease of use, reliability and durability are paramount.
The powerful 400 or 500 amp power sources provide reliable welding results with efficient ignition. Suitable for use with a wide voltage network, Master S also integrates Voltage Reduction Device (VRD) for increased safety at work.
