You might want to look up the April 18th, 2004 thread here entitled "bandsaw blades".
Use Google groups search.

The above must all be on the same line to work.
Several ways (including TIG) are discussed.

Hi Phil, This question seems to come up quite often. If you've got some pictures and an explanation, I can post this on WeldingFaq.com so folks can refer to it from time to time.

Bandsaw blade blade welder is easiest way to weld bandsaw blades.Even made in china blade wleder is expensive. Here is a web page selling a bandsaw blade welder powered by 12V battery.

Should be easy to make your own copy.

Probably because the company buys the cables. I would suppose that whomever makes the cables doesn't have much of a demand for two blacks or two reds on one cable.

Maybe there is some electronic stuff in there - just not a starter solenoid. Could be a switcher for a high voltage spike to get things rolling.

If Martin is right, then it may become a little more complicated.

I suggest that a Ford auto type of starter coil that is controlled by 12 V and then witches the high current - use battery charger or larger wire inside... Use lugs or make one out of thick soft copper.
I figure if a starter coil on the side panel will start a 1955 Ford when it is cold - It should melt and weld the ends.
The coil keeps the requirement of 100 amps or so off the push button. Ok - you don't have to use a FORD one - but Chevy IIRC, put them inside the starter... Maybe a John Deer :-) I bet a farmer thought of it 50 years ago anyway... :-)
