For anyone interested, I’ve just finished my first project with the unit - which involved several hours of welding 5mm steel. Very happy with it, it is very precise as you’d expect and I think TIG is my new favourite welding process even though it is a bit slower. Accuracy of welds, no splatter and precise heat input for what I’m doing are big pluses.

Have been running the unit quite hard up around 140 amps and I know the cheaper units with 15% duty cycles up at that range would have quit with what I did. This one runs 100% duty cycle at 160 amps, so and only drops to 80% duty cycle at 185 amps.

For heavy work I now see why a water cooled torch is a plus - While I don’t need to run out and buy one now, it may be on my shopping list at some point.
