I am also wondering exactly which sort of welder to buy. And how powerful a MIG has to be etc.
What is the deal with the gas.. how much does it cost, how much do you use and where do you get it from?
Is it best to buy the welder from a tool shop or where else?
thanks

Julian,
I'm using a mini-roll of 0.6 wire, this was recommended to me for car
panelwork, worked well on my baffled sump welding and bodywork but I need
more practice, it's pretty easy to burn a hole right through. I am an expert
Arc (rod) welder, but I can't seem to make my MIG welds as neatly as Arc
welds. I have a big roll of 0.9 wire with which it is just possible to
repair panels with but not easy. 0.9 is probably better for thicker-walled
exhaust tubing and flanges. Go the 0.6 for panels, I'm using Argoshield (a
mixture of Argon and CO2) gas on a Butters MIG single phase (home power
point) welder. Practice on scrap before you start welding your priceless
1600 panels!
If you want to weld Stainless Steel, it requires a TIG welder. My mate did
weld up a stainless fuel tank using plain steel wire and a MIG welder but
the welds will rust if left untreated (on the outside of the tank anyway).
It's not the normal way to do it.
You can just swap the gas on some MIG welders and get a different handpeice.
TIG welding requires different electrical pulsing and not all MIG welders
have the ability to change the pulsing. TIG welding is also not wire-fed
welding, you have a Tungsten handpiece and you use a rod to weld with. The
gas used in TIG (for stainless, aluminium and alloy) is pure Argon, not
Argoshield.
Hope this helps.
Regards,
Rob P

hi, get a gas welder, NOT a gassless.as
the gassless gets HEAPS more spatter, and the finish is no where as good
the gas.thinner
i would be using just about the thinnest mig wire possible for what yor
using, my brother had .8 or something mig wire, then went down to
mig wire , and he said it made a heap of difference.
he mainly welds car panels and other thin metals.

I remember reading ages ago a thread about which welder to buy, and what
you need to look for etc but I had a look for the archives but there
doesn't seem to be any???
Anyway, I figure im gonna spend between $500 and $1000 on a welder , i
guess MIG, mainly to do exhausts, body work, fix the garage etc. Maybe
a turbo manifold if I am any good at welding.
Basically I am wondering what power to get, where to get it, what to
look for, gas or gas less? Im in Melbourne so can you suggest anywhere
to buy it from?
I have a friend who is a stainless worker who is going to teach me how
to weld (he doesn't know it yet!) so hopefully I can work it out.
thanks
