WARNING
GENERAL DESCRIPTION
The SP-100T is a complete semiautomatic constant-
voltage DC wire feeder / power source arc welder. It
has been designed for workshop, hobby, automotive
and light maintenance. Included is a tap-switch con-
trolled, single phase constant voltage transformer /
rectifier power source and a wire feeder welding gun
for feeding .023 - .025
”
(0.6 mm) through .030
”
(0.8
mm) solid steel electrode. An optional kit is available
for feeding .035
”
(0.9 mm) Innershield
®
NR-211-MP
flux-cored wire.
The SP-100T is ideally suited for individuals having
access to 115 volt AC input power, and wanting the
ease of use, quality and dependability of both gas
metal arc welding or GMAW (also known as MIG
welding) and the Innershield electrode process (self-
shielded flux-cored or FCAW). The SP-100T is a
rugged and reliable machine that has been designed
for dependable service and long life.
RECOMMENDED PROCESSES
The SP-100T can be used for welding mild steel using
the Gas Metal Arc Welding (GMAW or MIG, Metal
Inert Gas) single pass process, which requires a sup-
ply of shielding gas, or the flux-cored arc welding
(FCAW) process using Innershield
®
electrode wire.
The SP-100T is configured for use with the GMAW
process as delivered from the factory.
OPERATIONAL CONTROLS
The SP-100T has the following controls as standard:
Control Power ON/OFF Switch, Voltage Control, Wire
Speed Control, Trigger Switch, and a Circuit Breaker.
