Hi Steve,

Good idea except the heat generated may make your electrodes go soft and bend away,

I remember an industrial spot welder had 25mm diamenter electrodes about 150mm long top and bottom clamped solid and insulated,

so all you need to do is have a say 10mm diamenter electrode rod with the touching ends turned to a smaller point  say 2mm and clamped solid to a heat resistant insulator. Dave I

 

p.s. after typing this I though I better check out if I was leading us in the wrong direction and found this:-

see the Duty Cycle is only 30%, which means use for 10 minutes and wait 20 minutes before use again I think?

where as your one could be 100% with beefy parts.

I got one of these from e-bay.

Wasted about 3 hours of my life using my HF inverting Welder on it - made all the right noises and sparks but I am yet to get the bloody thing to actually make 2 bits of steel stick together with it despite many attempts.

 

I havn't given up yet - maybe I could use the carbon electrodes from mine and use my welder but make up a set of timber clamps like this guy has made and see if that works any better.

Yes Steve,

And the trouble with both of them is that they are heavy as having the transformer built in,

so I found this that you could connect your own welding leads too:-
