Hello I'm getting back into welding after a long absence,
I would like to read an FAQ for this group or get specific info on some old torches I have.(and want to use)
I had the regulators and torches tested,repaired and all worn parts replaced(a few O rings,lines and valve diaphragms) the torches are manufactured by the "Canadian Liquid Air Company " the welding torch's body is labeled No.31111536(serial number) the mixer that screws onto the end of the torch body is labeled
LA-751 3-7
I have 3 torch tips LA-701 NO.2 LA-701 NO.5 and LA-701 NO.3
the cutting head is labeled "L.A. cutting attachment NO. 511
10108(serial number) the tip was replaced and I told him to put on "something that can cut up to
1/4 inch mild steel."
I'd like to know the safe working pressures in PSI that I should use these attachments with for O2 acetylene work.
I also have a EUTECTIC Hi-Lo Twinflame made in 1966 for sale. chromed body with a "W-7" tip on it for sale if anyone is interested. I have no use for it.(came with the liquid air torches)
I know the questions seem rather lame but the only training I had was a cursory intro in a refrigeration course....and that was a rather long time ago. I re-read the texts I have and all I got was don't run A into the lines at more than 15 PSI and set for the o2 pressure recommended by the manufacturer depending on what you want to do.
the closest I could find to a real pressure recommendation was 5/10 ac/o2 to weld and 3/20 ac/o2 to cut.
seems kinda vague to me and I'd like a second opinion before I strap myself to this bomb and try to have some fun.
thanks in advance Peter
