I need to patch together the generator bracket on my golf cart using my oxy/acetylene torch. (Note that I said "patch together." Calling my work with a torch "welding" is an insult to welders. I enjoy trying, though.)

I don't have the bracket with me, but I think it's about 1/8" thick, maybe 3/16".

The weatherman is calling for a high in the mid-30s this weekend. Is that too cold for welding?

No, just takes more gas and heat to get the desired effect. You might also want to keep the flame on the weld for a time after you finish, backing off slowly so it doesn't cool too rapidly.

An oxy/acetylene torch flame is around 5,000 degrees F - I don't think its going to take more than a couple of milliseconds longer to start the process with the base metal at 32F as opposed to say 70F.

The bigger effect will be the comfort of the person doing the welding, I don't know about the original poster but my fine motor skills degrade as the temps start falling.

is this a piece you can stick in the oven? are you brazing or using steel filler? if you can put it in the oven i would heat the whole piece first. if not, you need a way to cool it slowly. there is no such this as too cold for welding. just has to be done properly

The piece is small enough to put in the oven, but the only place my wife will let me weld () is a long walk from the oven. The piece will have cooled off substantially by the time I got it there. I was thinking of putting a heat gun on the piece just before and after welding.

Thank you all for the comments.
