Buddy Arc 400i & Buddy Arc 400i XC

The Buddy Arc 400i & 400i XC are heavy-duty, fan cooled, IGBT based inverter controlled power sources for MMA / TIG (scratch-start) welding. 

A wide current range and powerful welding performance make the Buddy Arc machines suitable for a wide range of MMA electrode types, such as:

- General purpose 
- Low-hydrogen
- Stainless steel
- Cellulosic

The Buddy Arc 400i XC model has controlled welding dynamics that provides even better weld properties for welding pipe root passes, e.g. with cellulosic electrodes.

The Buddy Arc machines are also capable of performing TIG welding with precise current control. All you need is an optional TIG-torch with a gas valve, a gas regulator and a cylinder of gas. You can weld mild steel or stainless steel material with or without filler material.
