Capabilities include MIG, pulsed MIG and flux-cored welding. Compatible with push-pull MIG guns. Increases productivity by allowing the use of 12-inch wire spools versus a spool gun’s 4-inch spools. Reduces downtime changing wire spools. Pulsed MIG welding delivers higher quality welds for ALL welders. • Lower heat input for less distortion on thin materials and better puddle control on out-of-position welds. • Less spatter minimizes post weld grinding and rework allowing more welding time. • Perform welding applications that couldn’t be done in the past, • Ideal for MIG welding aluminum...
