PRODUCT DESCRIPTION (PRODUCT
CAPABILITIES)
These small portable wire feed welders are capable of
MIG welding on steel, stainless steel, and aluminum.
They are also capable of flux-cored welding on mild
steel.
MIG welding stands for Metal Inert Gas welding and
requires a separate bottle of shielding gas to protect
the weld until it cools. Appropriate shielding gas
based on the type of material you are welding can be
purchased separately from your local welding gas dis-
tributor. MIG welding is ideal for welding on thinner
and clean materials when a very clean excellent cos-
metic looking weld is required. An example would be
automotive body panels.
Flux-cored Welding does not require separate shield-
ing gas to protect the weld since the welding wire has
special additives known as flux to protect the weld
until it cools. Flux-cored welding is ideal for medium
to thicker material and if welding on painted or rusty
steel. Flux-cored welding is also ideal in outdoor
applications where windy conditions might blow the
MIG shielding gas away from the weld. Flux-cored
welding produces a good looking weld but does not
produce an excellent weld appearance as MIG weld-
ing does.
Your machine includes the necessary items to weld
with either the MIG or the flux-cored welding process
on steel. To weld on stainless steel optional stainless
steel welding wire can be purchased separately. This
machine can weld aluminum using .035”(0.9mm)
diameter 4043 aluminum welding wire. Since alu-
minum welding wire is soft an optional aluminum
spool gun is recommended for best results. A welding
Procedure Decal is located inside machine door to
help provide suggested settings for welding.

ELECTRIC SHOCK can kill.
• Do not touch electrically live
parts or electrode with skin or
wet clothing. Insulate yourself
from work and ground.
• 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.
• Do not weld on closed contain-
ers.
