I know this is my 3rd post today! Sorry!
I've just follwed the advise on the regulator - thanks, but seem to have another more serious problem!
I have a greenbird AC/DC TIG on loan / purchase from a mate, he never used it. So i've gone and bought all the kit.
I switched it on the first day it came in the house - no torch or anything attached, just for 10 or 15 seconds to see the display light up etc. anyway it read 001 on the amps readout - i thought it was odd as the amps dial was at about 120 ish. I assumed it needed all the stuff attaching so switched it off and over the last few weeks I've bought all the stuff for it, regulator, argon, new bench grinder for the tungsten and I've been reading LOADS of tutorials and generally bugging the hell out of you guys!
Fired it up yesterday for a few seconds as I posted yesterday, very queit arc, all looked good.
Ground down the tungsten to have a proper go tonight, set it all up, got the gas working properly, set the amps at 120ish, and tried my hand on a big bit of thick flat I;ve got. All it did was tickle the surface... I thought that was odd - so looked at the readout (I hadn;t looked at the readout before now since the first time i fired it up) and low and behold it still reads 001.. no matter how much I turn the amp nob or change from DC to AC the readout doesnt change.
So i figured maybe the flat was just too thick - and not wanting to blow the 13amp fuse I thought of another option - thin stainless.
I;ve got a big sheet of the stuff, its about 1mm thick (maybe a bit less), so I cut a strip and folded it into a box section, clamped it lightly in my vice and tried it on a much lower setting (off the dial - remmeber the readout is still 001) probably about 30 amps - the stainless just laughed at it, I think I would have done better with a soldering iron!! So i cracnked it up to about 120ish amps thinking I'll blow holes in it, and at least prove the thing works - NOPE, exactly the same result.
Is it fubbard or am I making a school boy error. My only other welding experience is ARC so this is very high tech in comparison!
Thanks for your help guys, I really dont want to go back to my mate and say his welder doesn't work so I wont be buying it!!
