The RAZOR MULTI PROCESS SWF series is designed for maximum performance, offering the highest quality of welds from UNIMIG’s range, with the added flexibility of a Separate Wire Feeder unit.

The MIG250SWF is The RAZOR™ 250 SWF is a powerful workshop machine with MIG, TIG and STICK welding functions. This machine features the added flexibility of a Separate Wire Feeder unit, allowing up to 10m of extra manoeuvrability in the workshop.  

MULTI PROCESS WELDING:This three in one machine, lets you perform MIG, TIG and STICK welding all on one machine. There is also support for both gas shielded MIG and gasless MIG wire. There is no need to swap between machines, saving you time and setup. 

FOUR GEARED WIRE DRIVE:This machine features a four geared roller drive unit, providing the most consistent and smoothest wire feed. This also assists with using longer MIG Torches. 

SEPARATE WIRE FEEDER:Don’t get tied down. A separate wire feeder unit lets you remove the wire feeder from the power source up to a distance of 10m. This is perfect for workshops when moving a complete machine isn’t an option. 

SPOOL GUN READY: This machine is Spool Gun ready, so you have the option of attaching a Spool Gun to run softer core wires such as Aluminium MIG wire. The advantage of the Spool Gun is that you do not need to change the setup of your existing torch or drive roller. The spool gun lets you quickly switch over to get the job done with no downtime.

PUSH-PULL READY: Push-Pull Guns provide the smoothest wire speed, especially when MIG welding Aluminium. The ‘Pull’ motor in the torch allows the wire to be fed over a much longer distance, giving you more flexibility to move and manoeuvre whilst MIG welding.

HIGHEST QUALITY WELDS: Offering nothing but the best, this machine has been designed to offer the highest quality welds available from UNIMIG. With superior welding technology, no corners have been cut to make this machine the most powerful in its class.
