Versatility
Multiprocess Capabilities of MIG, Pulsed MIG, Stick (6010), DC Lift Arc TIG and DC Pulsed TIG
Easy-to-understand interface
7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time
Pulsed MIG welding delivers higher quality
Lower heat input for less distortion on thin materials, less spatter minimizes post weld grinding and rework allowing more welding time. Perform welding applications that couldn’t be done in the past
Auto-Set™ Elite
Offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels.
Program mode allows easy save and recall of favorite weld settings
Deliver more productivity, consistent quality by welders of all skill levels by using prequalified weld settings. Minimize supervisor need to intervene.
Portability - Machine only weighs 84 lb
Weight is reduced by more than 50 percent compared to transformer welding machines
EZ-Latch™ Dual Cylinder Rack with Elevated Gun and Cable Rack
Quickly disconnects from the machine and enables portability. Dual cylinder rack and storage compartment. Allows operator to easily store two gas cylinders. Includes elevated gun and cable rack to keep cables off the floor and tangle free.
Generator Compatible
