ESAB has updated its ST-21 and ST-16 MIG guns with a Euro-style back-end connection that makes them compatible with ESAB and competitive brand feeders. Both guns boast a 100% duty cycle at 600A and feature a design that can withstand the abusive environments of shipyards, mines, railcar, trailer, construction and heavy fabrication sites. They are especially popular for pulsed MIG welding with 1/16-in. aluminum wires, tubular wires up to 7/64 in. and high-amperage spray and pulsed spray transfer applications.
ST guns come in two styles to match customer preference. The ST-16 EU has a slightly curved style handle, a 55-degree “gooseneck” style conductor tube and a 10-ft. cable. This design is compatible with portable welding tractors such as ESAB’s Miggytrac B501 or B5001. The ST-21 EU is a pistol-grip/inline-style handle and comes with a 12-ft. cable.
The ESAB ST-21 EU and ST-16 EU guns are sold separately or as a total package with many of ESAB’s systems, such as ESAB’s Aristo® and Warrior® power sources and RobustFeed or AristoFeed wire feeders.
