UNIMIG Razorweld 175 MIG/MMA

Available in stock


unimig-razorweldRazorweld Series 175 MIG/MMA is an inverter-based portable MIG welding machine with added MMA function. The MIG function allows you to weld with both Gas Shielded and Gasless wire applications.  Easy step-less 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 stick out ready for the next weld. MMA welding capability delivers easy electrode welding with high quality results, including cast Iron, stainless and low hydrogen.  An additional feature is the Spool gun ready function 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. This is an industrial quality machine that is both lightweight and portable and an optional trolley with cylinder rack provides off the floor operation and better manoeuvrability around the workshop. Being 240v single phase gives great versatility. Ideal for general engineers, maintenance workshop, rural workshop, panel beaters, home workshop. Designed and built to our specification.

Quick Overview


Pure Welding Performance

The Razorweld 175 MIG/MMA machine is the ideal machine for light industrial and panel 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 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.

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


Voltage Reduction Device


Voltage Reduction Device (VRD) is a safety feature when operating in MMA/Stick mode.
VRD reduces the maximum unloaded open circuit voltage across the output terminals.

This makes the machine safer to use and is an industry standard in the welding industry.
