OPERATION

GENERAL DESCRIPTION

The machine is a semiautomatic constant voltage DC
arc welder. The machine uses a single phase con-
stant voltage transformer, solid state rectifier and a
DC permanent magnet motor for feeding and welding
solid steel electrode and flux-cored electrode.
The machine is ideally suited for individuals having
access to 115 volt AC input power and wanting the
ease of use, quality and dependability of both metal
inert gas (MIG) welding and the Innershield electrode
process (self-shielded flux-cored welding). The
machine will handle reels of wire up to 2 lbs(1 kg).

RECOMMENDED PROCESSES

The machine can be used for welding carbon and low-
alloy steel with CO 2 or argon/CO 2 mixture shielding
gas. The welder can also be used without gas for the
self-shielded, Innershield electrode process. The
machine is configured for the Flux Cored Arc Welding
process as delivered from the factory.
OPERATIONAL FEATURES AND CONTROLS
The machine has the following controls as standard:
• Power ON/OFF Switch
• Heat Range Switch
• 1 – 2 Fine Heat Adjustment Switch
• Wire Speed Control
DESIGN FEATURES AND ADVANTAGES
• Operates on 115 volt input.
• Solid state output control.
• Overload protection - incorporates a thermostat to
protect the welder from overheating caused by mal-
functions or overly heavy use.
• Permanent magnet wire drive motor.
• Easy-to-set controls for arc voltage and wire speed.
• Thumbscrew release idle roll pressure arm is easily
adjusted.
• Reversible, dual groove drive roll will feed .023-
.035" (0.6- 0.9 mm) diameter wire.
• Accommodates spools of wire up to 4"(102mm)
diameter.
• No external shielding gas is required when used
with Lincoln Innershield .035" (0.9 mm) NR®-211-
MP electrode.
• Easy to change polarity.
