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. With color-coded, quick connect/disconnect water lines and internal connections for shielding gas, the ST-16 EU and ST-21 EU guns are ready to weld in less than a minute.
Both guns boast a 100 percent 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.
“Our customers love the ST-21 and ST-16 guns because they increase uptime and productivity. They have earned a reputation as the industry’s most reliable, most durable gun,” says John Esposito, ESAB Global Product Manager. “We didn’t change a thing on the front end. We just redesigned the back-end of the gun so it can be used with any water-cooled feeder with a Euro-style connection and added an even more durable cable protector.”
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, which clamps a regular torch in a holder for mechanized welding. 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.
