SAFETY PRECAUTIONS

Read entire operation section before operating
the WIRE FEEDER WELDER.
WARNING
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 containers.
ARC RAYS can burn eyes and skin.
• Wear eye, ear and body protection.
Observe all safety information
throughout this manual.
PROduCT dESCRIPTION (PROduCT CAPABILITIES)
This small portable wire feed welder is capable of MIG welding on
steel, stainless steel, and aluminum. The wire feed welder is also
capable of flux-cored welding on mild steel.
MIG welding stands for Metal Inert Gas welding and requires a
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 distributor.
MIG welding is ideal for welding on thinner and clean materials
when a very clean excellent cosmetic looking weld is required. An
example would be automotive body panels.
Self Shielding Flux-cored Welding does not require a separate
shielding 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 welding 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
aluminum 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.
