hey, can you explain mig and tig welders.
i dont exactly know how they work.

I learned to weld on a stick welder, which is hard to master, even oxyacetalene welding ( gas welding), but it seems that MIG & TIG are the norm nowdays......I mean I can do them all, but for cleaner welds and ease of operation....Mig is the way to go, also Tig is very good as well. But we will have to see how the other person does.....but good luck doing it....

They are wirefed with gas, clean and able to weld smaller beads. I believe they use hydrogen to feed the wire, can't remember though, it has been some years for me. Do a google on them to get more info.

actually the mig welders I used....at least in high school and in the Navy....we used Argon gas....which the gas doesn't feed the wire....inside of the welder is a wire feeder...and what the gas does, is it sheilds the weld from contaminants, while you are laying down the bead....

yeah, i always seem to forget google is here to help, hehe:005:
i used a half automatic once or twice, pretty darn cool to do.
is also with gas and wire.
thanks guys.

no problem, just glad to help...good luck with the venture

If you run out of the gas, the wire won't feed at all.

Newe.....that's true.....it's a built in feature.....but I havn't touched a welder since 1998, so things could have changed.....but you do have a valid point.....no gas.....to sheild the weld area...no wire feed.....

the half automatic i used in the past was feeding wire with a motor.

It's both from my experience, but like you said sjcrss, it has been a long time! LOL, but from my experience, no gas, no feed. There is a spool that feeds the wire, but I think they work hand in hand.

also it depends on the material its made out of......example GPM leared that it isnt the best hoping up a 10+lbs truck..... RPM was my next upgrade and felt that they were enough to ceep my truck durable.

A MIG welder can be used without the gas. You change the wire from solid core to flux core and can weld like an arc welder but with greater precision.

Gas for MIG welding is typically ARGON or ARGON/CO2 depending on the material being welded.

The gas shield not only "shields" the weld bead from inputities but it reduces welding"spatter" dramatically as well. (Looks way better when you're done!)

Just go to the yellow pages and find a welder. There are tons of them. If you can find a welder the does tool and die repair they will have the skill to weld the small pieces you are looking for. Those guys can lay down some really fine beads.

You can use a TIG welder too can't you?

my dad's work buddy can do stainless steel.
maybe that would work aswell.
just gotta search a little more for info.
how would SS compare to alu weight wise?
but anyway, thanks for all the assistance guys!
