Professional welder which is very user friendly.

I use this for all kinds of TIG work in my own home workshop and for other people. At work I have a miller dynasty and this machine is quite comparable considering the price! It’s a little bit bigger and heavier but sits nicely under my bench. The arc is nice and smooth and all the features are fun to play with. The foot pedal is very nice to use and although I haven’t used the torch that comes with it (as got the ck9 flex as well) it looks very good quality. I would definitely recommend this machine to all levels of user.

*** what a piece of kit ... absolute love this welder ... tested on aluminium,stainless and mild steel .. couldn’t ask for better results all round ... highly recommend R TECH .

Product is being used at a school. Product quality looks good

excellent machine I fabricate turbo manifolds in sch 10 stainless steel my customer likes to see an even weld that's got good penetration but minimal discoloration(as the welds are left as laid).The machine has everything needed to cope with the demands I put on it.the settings are very easy to change and adjust as well as understand. I'm very happy with this product and would recommend r-tech to anyone buying a new machine.
