Hi good people.
I've done a couple of courses where we used a gas and air torch enabling much quicker heating of steel for punch making.
However, I can't seem to find one for sale and I'm not exactly sure of the functioning ( compressed air?).
All I have seen is what looks like the same torch head with two pipes.I'm struggling at home with just a Sievert and bottle of propane.
Any ideas please ?
