A guy I work with turns of the torch one way, I do it the other. Wondering who is right...
I like to follow the manufacturer's (victor) directions and turn off the oxygen and then the fuel gas. He likes to do it the other way. I think harris reccommends doing it gas first and then oxygen. Like my coworker says.
His argument is that his way is what he learned in welding school, and that they said it somehow keeps down soot buildup inside the torch.
My argument is that it causes flashback into the torch when you cut of the fuel gas first. IMHO any flashback is bad and should be avoided. It also seems easy for amatuers to leave the oxygen on because there is no longer a flame with the gas cut off. When the oxygen is cut off first, it is still obvious to the students that I work with that they still need to cut off the fuel gas.
Anyone know if there are AGA or OSHA rules/reccomendations on proper practice, and where I might find a copy of them? I wouldn't care too much, except that we are in the business of teaching a bunch of unruly art students how to weld, and I would like that they be given the most sound information available as to proper and safe work practices.
thanks,
jon
