I would be impressed if he could do it without the clamping bars.It's a bit pointless unless you have bought a really big turkey but Google welding aluminium foil and you can see videos of it.
Or do it overhead with 4mm rod in a stick welderI would be impressed if he could do it without the clamping bars.
^^^ how is this possible? Lol
We used to demonstrate the versatility of the EWM Tetrix 230 by setting it to AC special pulse and welding a piece of 1mm ally sheet to 10mm ally plate, it looked a bit like your razor blade setup but in truth its a bit of a gimmick as nobody does a weld like that in the real world. However it did serve to demonstrate the level of control and precision available in the machine.
once seen a lad weld 0.0 mm (his actual weld fell off both bits of sheet just held to nothing) does that count
