Versatility
Capable of MIG, Pulsed MIG welding for any steel, Silicon Bronze or Aluminum application
Easy-to-understand interface
7-inch color LCD display ensures proper machine setup and parameter selection, reducing setup time and increasing weld time
Auto-Line™ Technology
This inverter power supply allows for any single-phase input voltage hookup (208–240 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.
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.
