The UNIMIG RAZOR COMPACT 350K-SG is a powerful workshop machine with MIG, TIG and STICK welding functions. Built with solid construction, this machine is designed to withstand the toughest conditions. The RAZOR™ 350 Compact is also Spool Gun and Push-Pull Gun ready, providing MIG welding capabilities across every spool size.

The RAZOR™ Compact series is designed for superior performance, offering the highest quality of welds from UNIMIG’s range.

  • The MIG function allows you to weld with both Gas Shielded and Gasless wire applications. Easy stepless adjustment of voltage and wire feed make for easy setting of welding parameters giving excellent, professional welding results.

  • Wire inch gives easy feeding of the wire during set up without gas wastage and the Burn Back adjustment leaves the wire out ready for the next weld. An additional feature is the Spoolgun ready function that  allows the simple connection of the PLSP240 Spoolgun for the use of thin or softer wires that don’t have the column strength to feed through standard MIG torches, such as aluminium wire. Added MMA welding capability delivers easy and high quality welding using electrodes, including cast Iron, stainless and low hydrogen.

  • Connection of the 26V TIG torch provides quality DC TIG with Lift Arc start for welding of steel, stainless steel and copper.

  • The machine is industrial rated and of solid construction, large industrial wheels allows easy and smooth manoeuvrability.

  • Ideal for general engineers, maintenance workshop, rural workshop and tafe colleges. Designed and built to our specification. Certified to – AS/NZ60974-1
