OPERATION

PRODUCT DESCRIPTION (PRODUCT
CAPABILITIES)
.
The portable AutoPro™ (140/180 MODELS) is capa-
ble of MIG welding on steel, stainless steel, and alu-
minum, 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 pan-
els.
FCAW-S stands for Self shielding Flux-cored Arc
Welding and does not require a shielding gas to pro-
tect the weld since the welding wire has special addi-
tives 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 applica-
tions 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 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 machine is spool gun ready and the
machine can weld aluminum using .035"(0.9mm)
diameter 4043 aluminum welding wire. Since alu-
minum 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.
