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

Wow it looks fantastic. Well made and we'll finished. As yet I have a long way to go but I'm sure that buying a quality bit of kit will help and there's always a knowledgeable person on the end of a phone

The welder is used most days. I am very pleased with the product as it is very good quality

A great welder

By moving to this welder we've come up to date with what modern tig sets can do. The weld pulse is a great plus. Weld penetration is so much better than my old Miller. Easy to set up, after a few minutes I was getting welds using less heat with better penetration yet less distortion (on 2mm CR steel). The torch is comfortable and looks like it will cope with industry. The tig set looks robust and well put together.

Good piece of kit. Can't report on the reliability - too early!!
