WARNING
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).
