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. This machine can weld aluminum using

.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.
