Power Factor Correction - What is this?Gives lower running costs, it is more energy efficient, cleans noisy power supplies & is 100% generator friendly

4 AC Waveforms
- Advanced Square Wave: fast cooling weld pool, deep penetration and fast travel speed
- Soft Square and Sine Wave: Lower arc noise, for a more traditional arc
- Triangular Wave: designed for thin alloys, reduces heat input

HF Microstart - improved arc starting and less interference - What is this?Ensures an ultra-clean start to your welds
Lift Tig start option when welding near sensitive electronics - Automotive ECUs etc
VRD Voltage Reduction in MMA - reduces OCV in standby for increased user safety
Full 4-way functioning with control of pre/post flow gas, initial/final amps, slope up/down
Generator Friendly - Recommended minimum of 6KVA
LED display for preset and actual amperage
MMA Anti-Stick, Arc-Force & Hot Start technology

Bought this unit for welding (not brazing) thin brass sheet. The advanced pulse function is a god send! I effectively weld using DC with a small amount of AC added (triangular wave) for cleaning and heat control. Seems to work really well. I will be buying the additional 2 year warranty at the end of my initial 3 year warranty!!!! 5 year warranty!!!! Who does that!!! Apart from KIA and they don't make welders!

I wanted an AC capable TIG machine as I need to weld aluminium for a car I am building. Up until buying the R-Tech machine I had been using a very cheap DC-only TIG with the most basic features. The new R-Tech is a joy to use. Quality is excellent, everything has a solid feel to it. Great features.

Never TIG weldered before but this machine makes it easy.I got the welder for hobby use but you could run a small buisness with it.

for work and hobby.

Hobby use, professional and hobby users, very good quality, stable machine and well built. Hard to beat at the price.
