OPERATION
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.
The term "MIG" 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 pur-
chased separately from your local welding gas distrib-
utor. 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 auto-
motive 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 welding does.
Most machines include the necessary items to weld
with either the MIG or the flux-cored welding process
on steel. The 125 amp units will require the addition of
a 'MIG Conversion Kit' (K2526-1) for welding gas
shielded processes. To weld on stainless steel option-
al stainless steel welding wire can be purchased sepa-
rately.
.035"(0.9mm) diameter 4043 aluminum welding wire.
Since aluminum welding wire is soft an optional alu-
minum spool gun is recommended for best results. A
welding Procedure Decal is located inside machine
door to help provide suggested settings for welding.
