With the lack of an AC tig machine and an AC inverter appearing to not
be in the cards in the near future i"m looking at using Oxy/Acetylene to
do the al Welding due to the availability of an OA rig. Mainly i used it
for cuttingbut thats not to say its impractical for welding. If i
remember right OA has been used for Al welding for a long time
specifically in the aviation industry.

Compared to TIG how hard is OA welding of aluminum and are there any
special types of requirements for doing it? The only OA welding i would
be doing would be on Al and the rest of the time it would be used for
heat/cutting

I already have an OA torch (Cheap Harris style kit) but stumbled across
a real Victor 100 Handle Might i be better off getting a fresh welding
tip for the victor 100? than the giant beast of this harris one?

I will likely never weld larger than 1/4" with most work being smaller
than that (1/8" to 1/16")

the Victor 100 seems to be the most like the tig torch i'n used to
compared to the big beast of the current torch. If thats the case than
has anyone used gas quick connect fittings to swap torches and are those
reliable or am i looking to blow myself up

BLowing myself or the shop/house up is EXTREMELY LOW on my list of
priorities
