Hobart Welding Products’ new kit allows heavy MIG welders to be moved easily. The product features a portable CO2 cylinder kit that is compatible with many popular MIG welders and comes bundled with Hobart’s Handler 104 unit. The kit’s 20-ounce paintball cylinder design improves the portability of small MIG welders and is an affordable and convenient alternative to bulky gas cylinders. It can be refilled at most sporting goods stores for about $3. The kit can be mounted on Hobart’s Handle 140, 187 and 210 models and can be adapted to fit many other popular MIG welders, Hobart said.
