Always wear dry insulating gloves.

FUMES AND GASES can be dangerous.

Keep your head out of fumes.

Use ventilation or exhaust to remove fumes from breathing zone.

WELDING SPARKS can cause fire or explosion.

• Keep flammable material away.

ARC RAYS can burn eyes and skin.

• Wear eye, ear and body protec- tion.

Observe all safety information throughout this manual.

GENERAL DESCRIPTION

The SP 170-I is a complete semiautomatic constant voltage DC portable arc welder. Included is a tap- switch controlled, single phase constant voltage trans- former/rectifier power source and a wire feeder with welding gun for feeding .025" (0.6 mm) through .030" (0.8 mm) solid steel electrode and .035" (0.9 mm) Innershield® NR-211-MP.

It is ideally suited for individuals having access to 230V 50/60 Hz AC input power and want the ease of use, quality and dependability of both gas metal arc welding 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 is designed for dependable service and long life.

RECOMMENDED PROCESSES

The SP 170-I can be used for welding mild steel, stainless steels and aluminum using the GMAW, sin- gle pass, process (MIG) which requires a supply of shielding gas or it can be used for the self-shielded, Innershield® process (FCAW).

OPERATIONAL FEATURES AND CONTROLS

The SP 170-I has the following controls as standard: Power ON/OFF Switch, Voltage Control, Wire Speed Control, Trigger Switch, and a Circuit Breaker.

DESIGN FEATURES AND

ADVANTAGES

“Cold electrode” until gun trigger is pressed for an added measure of safety.

Overload protection — incorporates both a thermo- stat and a circuit breaker.

Quality wire drive with electronic overload protec- tion.

“Quick Release” idle roll pressure arm is easily adjusted.

Reversible, dual groove drive roll, shipped ready to feed .030" (0.8 mm) diameter solid wire or .035" diameter flux-cored wire. The drive roll is easily reversed to feed .025" (0.6 mm) diameter solid wire.
