Hobart Welding Products has a new portable CO2 cylinder kit for small MIG welders. Compatible with many popular MIG welders, the kit is sold separately (suggested price is US$119) or bundled with Hobart’s Handler 140.
The 20-oz cylinder is the same type used for paintball guns, the company says. A full cylinder will deliver roughly 40 minutes of continuous arc time on mild steel. Using CO2 as a shielding gas offers the advantage of providing better penetration during the weld with minimal spatter due to Hobart’s patented design.
“We were pleasantly surprised with the arc quality using CO2,” says Chris Croatt, product manager for Hobart Welding Products. “The real benefit is the portability. Welders can now get the most from their small MIG units by not having them connected to a large, heavy tank.”
