The Warrior and Aristo Mig systems from ESAB provide Trailstar with reliable, highly efficient performance through two daily shifts of high arc-on time, high amperage welding.
However, in Trailstar’s eyes, the real rock star of their MIG aluminum system is the ST-21. This MIG gun is water-cooled all the way to the tip, is rated at 600 amps with any shielding gas, has an in-line nozzle and pistol grip handle. Because 1/16-in. aluminum has sufficient columnar strength, it can be run through push-only MIG systems with gun cables up to 12 ft. long.
“If you’re welding aluminum, the ST-21 is what you want. It’s the Cadillac of welding guns,” says Mike Schmidt, Trailstar’s service and shop manager.
