Bit baffled, have I got the right set? can't see it does TIG??
Can't see you getting much of a kit worth having for £40. Double that and you might be getting somewhere near for a decent make of torch.
Cancel the order on the regulator, it won't fit. Also barking up the wrong tree on the gas cylinders, you need 100% pure Argon for TIG, totally different regulator connection & much higher cylinder pressures, so CO2 cylinders are no good.
Cancel all those orders. That's gonna be a painful ordeal.
£78 all in from Steve ready to go is a no brainer!!!
