2.05 Description
The Cigweld Transmig 400 i is a self contained three-
phase DC arc welding power source with Constant
Current (CC) and Constant Voltage (CV) output
characteristics. This unit is equipped with a Digital
Volt/Amperage Meter, lift arc starter for use with Gas
Tungsten Arc Welding (GTAW), and Control and Hot
Start for Shielded Metal Arc Welding (SMAW)
processes. The power source is totally enclosed in
an impact resistant, flame resistant and non-
conductive plastic case.
NOTE
Volt-Ampere curves show the maximum
Voltage and Amperage output capabilities
of the welding power source. Curves of
other settings will fall between the curves
shown.
