The RazorWeld 200AC/DC is the new benchmark for Single-Phase Welding in Australia. This machine is fitted with some of the latest feature available on the market and has extreme versatility of use on aluminium, stainless steel and other metals, for under $2000.

The machine is the first UniMIg machine of its type to feature full digital controls and Digital Square Wave. The Digital controls allow for ultra precise TIG welding on thin gauge aluminium and other metals. The machine features digital control of Press Gas Time, Up Slope, Down Slope, Start Current and Finish Current, not to mention Post, which all amount to professional welds.

When welding Aluminium, AC Square Wave gives you maximum control of the electron flow. This allow you to set your AC TIG arc for maximised cleaning of the oxide layer when welding aluminium. The machine also features Digital Pulse Frequency Control, which gives you precise control of your Peak Current, Base Current, Pulse Fequency and Pulse Width.

The machine comes with a high frequency SR26 Torch with 2T/4T Trigger control. UniMig’s unique remote torch control interface gives you the ability to control amperage from your torch in both static and live weld modes. The machine features HF TIG capability in both AC and DC and is ideal for professional welding of aluminium, steel, stainless, copper, bronze, and cast iron.

The machine also comes with an arc Welding Lead Set, allowing you to Stick (MMA) weld.

ExcellentReview by Loumar
Great little welder & very well priced (Posted on 13/07/18)
Great first welderReview by Austin Mark
This is my first TIG so I cant offer any comparisons but I have to say that this one has fully met with my needs and appears of good quality. Ive been using it on thin sheet steel and ally for a couple of months and find the after a bit of trial and error I can find settings that compensate, at least in part, with my terrible technique ;-)

I'd fully recommend getting a full featured machine as a first device (Posted on 23/07/17)
Fantastic welderReview by Stephen Vines
I got one of these a few weeks ago. It is very well priced, easy to use with all the functions I needed.
Thanks (Posted on 21/07/17)
Hasn't missed a beatReview by David, Maryborough
Have had this for six weeks now. Very happy with the performance on light aluminium. Yet to run it in DC. Pulse frequency gives really good control of the weld. The AC Square Wave control is also excellent for cleaning of the metal. Foot Pedal took me a little while to get used to but is OK. (Posted on 17/08/16)
HappyReview by Daniel, Melbourne
Best AC DC TIG I've owned. Use it for 1.6 and 2.4mm tack weld son Ally mainly. Duty Cycle very good. Regularly do 30 to 40 shorts tacks with out overheating. Quality clean welds.Took me a little while to get used to setting but all good. (Posted on 8/07/16)
Quality MachineReview by Tristan
Amazingly light weight but output and duty cycle are really good. Excellent control and weld performance on light and medium Ally. Pulse function very easy to use and precise with the digital settings. Instruction manual could be a fraction more detailed but very happy. Thanks eWelders and UniMig (Posted on 17/06/16)
