Welcome to the future of Multi-Function Inverter Welders!

Part of UniMig's flagship Razorweld range, the 205 Smart Set features 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. Easy step-less adjustment of voltage and wire feed coupled with integrated digital meters allows easy setting of welding parameters. The MIG 205SS features Smart set welding with four Synergic Mild Steel welding programs designed for ease of use with your selected gas mixture.

This machine weighs 12.5kg - up to 40% lighter its competitors. But - with a 200amp output - it is capable of performing semi Industrial Function in MIG, TIG or MMA and it's at a price point that brings it to within reach of the serious DIY welder or the light industrial fabricator.

Easy step-less adjustment of voltage and wire feed make for easy setting of welding parameters ensuring professional quality weld, while the Wire Inch technology ensures easy feeding of the wire during set up and ensures no Gas wastage.

Stick welding capability delivers easy electrode welding with high quality results, including cast Iron, stainless and Low hydrogen. The machine also offers DC TIG Capability and features Lift Arc function for easy arc ignition - Every time! High quality DC TIG welding of steel, stainless steel, bronze and copper can be achieved even if you're TIG welding background is limited.

How do I weld aluminium you ask? Easy! The added Spoolgun ready function means the 205MTS means simple connection to the SPGRW200II Spoolgun which will allow you to run aluminium wires. This is an industrial machine that is both lightweight and portable. Being 240v single phase gives great versatility.
