stripped and tested the pot today and it checks out ok, 0-100k nice and smooth along its length (ooer Mrs), need to hook it back up and try it again I suppose.

D.

Might seem obvious but is it switched for foot pedal use (switch at far right of control panel) and check plug for same resistance value 0-100k....thats all that I can think of unless the problem lies within the internal gubbins:(

Both checked and ok, if it still doesn't work proper then its gotta be internal of the machine itself, might just be a short though.

Thanks for your help, D.

so chaps r-tech or the sip tig set both offer 2 years warranty.

If you stretch the budget a tad you could go esab and they are the dogs danglers.

If a chink tig set is £300 and say a Cebora set is £2500 for the same size machine it doesn't make the cheap one good value it means it doesn't work.

I would possibly look into staying away from sip welders. I am led to believe that they have bit of an industry reputation for being rubbish. I'm only basing this on their mig welders though and I think the main complaint is the wire feed. Obviously not a problem on a tig unit.
We had a sip 130 mig and it was pretty rubbish. sold it and got given a free oxford one which is far better even though its about 20 years older.

I'm a TIG welder by trade and I use a Migatronic or a Fronius everyday, they are Both DC only but are well over £3000 each so would not even consider buying either for home use.

For use at home in the garage I'd look at something like this:

I don't know how good it is but seems about the right price for a decent hobby set

if you want somthing like that go for a Thermadyne Arcmaster 175 TE.
i have used and sold a few in the past.
everything has estern origin parts in this end of the market but its in the real makes bracket.
what ever you buy keep it dry and clear of any dust and damp as its the main killer of tigs (pcb tracking out)
also keep an eye on your supply as v drop burns them out.

cheers chaps
had a chat with a couple of lads that have r-tech tig sets and one of our stainless welders used a parweld when he was out on site.looks like i,ll be getting a r-tech becaouse they have good backup this is what i will be making
