The stainless steel of choice in the food services industry is the austenitic 300 series. The stainless used for good pots (like Vollrath) is usually 304. Less expensive pots are often made of 303 alloy stainless, which is less weldable and is quickly attacked by chlorinated cleaners. Other stainless kitchen equipment, like utensils, are typically ferritic stainless, which has less chromium and nickel and is less acid-neutral.

Although welding stainless steel
may not be as difficult as welding aluminum, the metal does have its specific
properties that vary from your more common steels.
When MIG welding on stainless,
you usually have three choices of transfer depending on your equipment:
spray-arc, short-circuiting, or pulsed-arc transfer.

WELDING 101
We all know deep down inside that real men and real women don’t braze, they weld! Welding differs from brazing in that the parent metal is heated to its melting point, and filler metal, if used, is fed into the molten pool. When the whole mess cools, the parents materials have become fused at the joint.
For thin metals, use a smaller diameter wire. For thicker metal use a larger
wire and a larger machine. See machine recommendations for welding
capacity.

There is a lot more to MIG welding than just learning to run beads, but in this article, I’m talking fundamentals.
When did MIG start? MIG came about during World War II. It was developed to help produce weapons and equipment faster. It was then used in the postwar booming economy, mostly in shops and factories.
The LN-25 semiautomatic wire feeder is ideal for field or construction use. Since it is powered across the arc, no control cables are needed! Simply connect the weld cable, attach the welding clip, and you’re ready to go. The fully enclosed case ensures that this portable MIG and flux-cored wire feeder can tough out any work site.
This portable unit is designed for MIG or flux-cored wire feeding. The totally enclosed case accepts 10-44 lb. wire packages for welding versatility. The LN-25 features a tool-less quick release mechanism for easy wire changing.
Multiquip’s welder/generators are engineered with a new permanent magnet alternator plus features typically found only on much larger welders. Powered by an 11 horsepower Honda engine, The GAW180HE provides 180 amps of DC welding power, and also 3kW AC output which can be used simultaneously by the operator. The unit also features an electric start and lifting bail. Ideal for job site and remote-area service applications.
The Lincoln Electric Company’s Innershield semiautomatic flux-cored, self-shielded guns are rugged and reliable, ideal for bridge, ship, barge, machinery, structural and large fabrication applications, yet lightweight and maneuverable for smaller repair jobs. These guns feature a heavy-duty gun trigger switch, which provides positive electrical contact with enhanced durability. The guns are easy to operate with a reduced wire feed speed thumb switch and adjustable grip angle. Lincoln Electric’s line of Innershield welding guns have rated outputs from 250 to 600 amps and are intended for use with .062” – 3/32”, .068 – 5/64” or 7/64” – .120” diameter wires for flux-cored, self-shielded operations. The Innershield guns are each configured with a 10- or 15-foot gun cable with reinforced rubber jackets for added strength. Alternate gun tubes are available for selected guns to reach welds with limited accessibility and provide added comfort and performance for the most demanding applications and environments.
