GENERAL DESCRIPTION

The Handymig 170i is a complete semiautomatic con- stant voltage DC portable arc welder. Included is a tap-switch controlled, single phase constant voltage transformer/rectifier power source and a wire feeder with welding gun for feeding .023" (0.6 mm) through

.030" (0.8 mm) solid steel electrode. Optional kits are available for .035" (0.9 mm) and .045" (1.2 mm) Innershield® NR-211-MP.

It is ideally suited for individuals having access to 240 volts 50 Hz AC input power and want the ease of use, quality and dependability of both gas metal arc weld- ing or GMAW (also known as MIG welding) and the Innershield® process (self-shielded flux-cored or FCAW). A convenient chart is mounted inside the wire feed section door for setting welding procedures for 24 gauge (.60 mm) through 5/16" (8.0 mm) mild steel. The machine is rugged and reliable and has designed for dependable service and long life.

RECOMMENDED PROCESSES

The Handymig 170i can be used for welding mild steel using the GMAW, single pass, process which requires a supply of shielding gas or it can be used with the self-shielded, Innershield® process (FCAW).

OPERATIONAL FEATURES AND CONTROLS

The Handymig 170i has the following controls as stan- dard: Power ON/OFF Switch, Voltage Control, Wire Speed Control, Trigger Switch, and a Circuit Breaker.
