2.0 INTRODUCTION AND DESCRIPTION
2.01 Description
The Thermal Arc™ Model 185TSW is a self contained single-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.
