Subject: Re: [Healeys] Gas torch. No Healey....
As Michael said, your best bet for the task you describe is a MIG
welder. A gas torch will heat up a much larger area than you want,
and it will take some time for the target piece to reach a temperature
that is needed (meanwhile igniting surrounding combustibles). For an
expert weldor, a TIG welder can produce miracles. But for the rest of
us a MIG machine can do a lot.
A gas MIG would be best but even a cheaper MIG that used flux core
wire might get the jobs done. It would be cheaper.
