Hi All,
I'm looking for some advice on buying a DC tig welder for very thin walled tubing. I've got the opportunity to build a few high end steel bicycle frames but the 200amp SiP ac/dc machine I have isn't up to the job.
The SiP is OK on the general fab stuff I have been making (furniture, garden stuff etc) but it has a few problems when it comes to low amps. The footpedal gives the full 200amps (it bypasses the fascia control entirely) and on pulse setting the display just randomly jumps about so it's not clear what it's actually doing. It has other issues but they are the main ones for thin wall. I have managed to weld thin wall titanium with it though.
The tubes I'll be using will typically be .7mm down to .4mm thick. Only steel, no aluminium. The welds will not be painted.
My budget is £2500. I prefer to use a foot pedal and if possible I'd like to keep the CK torch I have.
It's my money btw! So if I can get exactly what I need for less I'm all ears!
