Unimig Razorweld 205 Smart Set 200amp Inverter MTS Welder



The Razorweld Series MIG205-SS is a new inverter-based portable MIG/MMA/TIG Welding machine with Synergic Programs for 0.8mm and 0.9mm solid welding wires. The MIG function allows you to weld with both Gas Shielded and Gasless wire applications giving excellent, professional welding results.

The Razorweld 205 Smartset is the ideal machine for light industrial fabrication work . The machine is lightweight and portable and perfect for site work. The MIG function provides superb arc characteristics when using either Gas Shielded or Gasless Wires. The machine features an adjustable Burnback control and easy to use panel layout to get your job done faster.

The Smartset function is a Synergic feature that allows you to select the wire size and gas mixture you are using and the machine will optimise the parameters for your job. Once welding you can still make adjustments to the Voltage control for fine tuned results.

The machine is also a very capable MMA (Stick) welder capable of running most MMA Electrodes up to 4.0mm. An added feature of Hot Start helps when striking an Arc to minimise the Electrode sticking to the work piece.

With the machine being Spool Gun ready a UNIMIG Spool Gun is available if you want to run Aluminium wire without the changeover in the torch, liner and drive roller. The Spool Gun is an ideal way to use softer wires and not have to purchase larger spools of wire for small jobs.

The Razorweld 205 Smart Set is also a DC TIG welder with Lift Arc function. DC TIG will allow welding of materials such as Mild and Stainless Steels as well as Bronze, Copper and Chrome Moly’s.

*Always refer to the recommended polarity setup as stated on the electrode packaging.
