160A AC TIG, capability ?
Looking at replacing my ancient mahoosive AC/DC TIG with something more modern.
Was curious as to what thickness aluminium it can weld. My current one has been used to repair
wheels and engine casings, would a 160A (eg R-Tech) manage that ?

Yesterday welded 10mm aluminium with 140A, ground a nice bevel on both sides and worked fine, 140A and full pedal was a bit on the hot side.
160A would be able to weld pretty much any thickness, sonething like a 1" tee joint would just take a couple of passes

I have the R-Tech 160 AC / DC and have yet to find anything it can't do within reason, sometimes it needs multiple passes and yes on thick Ali
it all gets a bit warm but as long you're not in a rush it copes well. I'm sure you've seen my post about the R-Tech discount code
for this month?

I use a map gas torch on castings with my r tech 160 , still needs pretty much full power to get going but the heat lets you back off a bit once your
flowing

Yes, it's old, big and heavy. Sureweld AC/DC 180. Currently set up for 240v single phase but can be switched
to 440v three phase.

Yes, torch on quite a long lead/pipe, gas pipe and a long earth lead.
Mains cable currently has a poorly fitted 16a plug but could do being on a 32a as
it trips my supply when wound up to the higher settings.
I'll be keeping the gas bottle and regulator.

remember in ac around half the current is goning the wrong way to break the oxide film
you want to go as big as you can so 200-250 is where you need to be to have a bit of kit thats useful but to weld wheels and castings you would still
need to pre heat

I've done a lot of 1/4 inch casting to 3.2 mm alloy tube, building manifolds, and 5mm to 5mm casting with the R Tech 160 on 100 - 110 amp no
problem..
When I bought it, I was going to go for the 200, but R Tech said on a domestic supply I wouldn't get any benefit from the extra 40 amps, as at
much over 160 it would exceed the supply current, and pop fuses / breakers.
