James,
I picked up and SIP mig from Alltools down in Ringwood. The one I bought is
still portable (bloody heavy), has copper windings, fan, reg, can't remember
how many amps 200? or duty cycle. Cost around $1150.

Thanks for all the replies
After a bit more research it is amazing what some of the
manufactures claim.
It seems the things to look out for are:-
Copper transformer windings (the cheaper ones have aluminum wire)
Cooling Fan (cheapies usually don't have one as standard)
Argon Gas Regulator included (it's extra with the cheapies)
and most importantly the Duty Cycle
Most of the cheap 170A are lucky to be actually 150A
The Duty cycle is the big thing.. A 170A welder with a duty
cycle of only around 20% @ 150A .... means that you can use
it for 2 minutes in every 10minutes at it's full power before it gets
too hot and you have to let it cool down....
So a high Duty Cycle is the most important thing to look at.
Anyway the short of it is that I have to save a bit more money to
get the one I want.
