2.0 INTRODUCTION AND DESCRIPTION
2.01 Description
The Thermal Arc
TM
ArcMaster 200 ACDC is a self contained single/three-phase AC/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 retardant
and non-conductive plastic case.
