WIRE FEEDER WELDERS (125, 140)
PRODUCT DESCRIPTION (PRODUCT CAPABILITIES)
The portable 125Amp Wire Feeder Model is capable of flux-cored
welding on mild steel. The portable 140Amp Wire Feeder Model is
capable of MIG welding on steel, stainless steel, and aluminum, in
addition to flux-core welding on mild steel.
MIG welding stands for Metal Inert Gas welding and requires a
separate bottle of shielding gas to protect the weld. The Shielding
gas used is determined by the type of material you are welding on.
Shielding gases can be purchased separately from your local
welding gas distributor. MIG welding is ideal for welding on thin
and clean materials when an excellent cosmetic weld is required.
An example is automotive body panels.
FCAW-S stands for Self shielding Flux-cored Arc Welding and does
not require a shielding gas to protect the weld since the welding
wire has special additives known as flux to protect the weld from
impurities. Flux-cored welding is ideal for medium to thicker
material and for welding on painted or rusty steel. Flux-cored
welding is also ideal for outdoor applications where windy condi-
tions 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 140Amp machine includes the necessary items to weld with
either the flux-cored welding or MIG welding process on steel. To
weld on stainless steel, an optional stainless steel welding wire
can be purchased separately. The 140Amp machine is spool gun
ready and the machine can weld aluminum using .035"(0.9mm)
diameter 4043 aluminum welding wire. Since aluminum welding
wire is soft, an optional spool gun is recommended for best
results. A welding Procedure Decal on the wire drive compartment
door provides suggested settings for welding.
