TRANSTIG 200 Pi
2.05 Description
The Cigweld Transtig 200 Pi is a self contained single-
phase DC arc welding power source with Constant
Current (CC) output characteristics. This unit is
equipped with a Digital Volt/Amperage Meter, gas
control valve, built in Sloper and Pulser, lift arc starter,
and high-frequency arc starter for use with Gas
Tungsten Arc Welding (GTAW), Gas Tungsten Arc
Welding-Pulsed (GTAW-P) Gas Tungsten Arc Welding-
Sloped (GTAW-S), and 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.
