WIRE FEEDER WELDERS (125, 140, 180 MODELS)
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.
Self Sheilding Flux-cored Welding does not require
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 diameter
4043 aluminum welding wire. Since aluminum weld-
ing wire is soft an optional aluminum spool gun is rec-
ommended for best results. A welding Procedure
Decal is located inside machine door to help provide
suggested settings for welding.
