Buddy™ Arc 400i / 400i XC
 
Compact and Powerful Inverter MMA Welder
 
Robust and Powerful
The Buddy™ Arc 400i and 400i XC are heavy duty, fan cooled, IGBT based inverter controlled power sources meant for MMA / TIG (scratch-start) welding.
 
MMA Welding
A wide current range and powerful welding performance make the Buddy™ Arc machines suitable for a wide range of applications and electrode types such as:
- General purpose
- Low-hydrogen
- Stainless steel
- Cellulosic
 
The Buddy™ Arc 400i XC model has controlled welding dynamics that provides excellent weld properties for welding pipe root passes.
 
TIG Welding
The Buddy™ Arc machines are 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.
 
Voltage Reduction Device – VRD
In some areas a voltage reduction device, or VRD, is required. VRD is a safety function that limits the open circuit voltage from the machine to less than 35V. The Buddy™ Arc are prepared for VRD and the function can easily be activated inside the power source.
 
Easy Settings
The simple control panel of the Buddy™ Arc makes it easy to optimise settings, reducing the time taken for achieving the best weld characteristics. These units are equipped with hot start and arc force with the possibility to adjust parameters during welding. Hot start helps to avoid starting problems while arc force sets the intensity of the arc for improved weld quality.

As an option the Buddy™ Arc can be equipped with a remote control unit.
 
Energy Efficient
The Buddy™ Arc machines are constructed to maintain a high power factor and efficiency, thus keeping the energy cost to a minimum without affecting the weld quality.
 
Safety and Reliability
The Buddy™ Arc machines conform to the International Standards that ensure the reliability and safe use of these machines.

These units are equipped with overheating and mains over/under voltage protection that will temporarily switch off the machines automatically to prevent any potential damage that the components might sustain.
