Default Help purchasing a welder

For the last few months I have been attend TAFE MIG course, and its about time I bought myself a welder to do some extra practice, as I am hoping to weld up some sliders, and possibly rear bar. Thinking of a welder in the 130-150amp range would be the go.

I have spent quite a lot of time reading hundreds of posts but I think I am now starting to confuse myself. Most of the consensus seems to be that purchasing a second hand 'known' brand welder is preferable to one of the hundreds of Chineese cheapies on Epay, and speaking to my teacher, he agrees. On the other hand, I don't like buying other peoples problems, especially when I don't know how to service/repair welders...

So, pls help me with a welder

Requirements are
weld 5-6mm plate single pass
not excessively concerned with duty cycle as I am happy taking my time
single phase
~$600 is what I can justify since there will also be consumables that I will need.


I have seen the following on the web

Nuweld POWERMIG 150
welds 1.00mm - 6.00mm thickness
100%@35A 10%@115A
going for $399 at Normist (not sure on delivery)

Unimig MINI-MIG 120
15% — 105 Amps
60% — 52 Amps
100% -40 Amps
$590 at Sydney Tools

might not have the grunt? don't know

Nuweld POWERMIG 175
100%@56A 15%@145A
$646 at national welding

Then I have seen a 25 year old! CIG TRANSMIG 195 that has apparently only run 5 rolls of wire since new, that apparently works well. I understand that these machines can readily be repaired, but not sure here.

any and all advice appreciated

as 1 of the better welders on this site (not my claim)
i you need to ask your self do i really need a mig welder
if answer is yes
the following is a consideration
cost= not only initial out lay but cost of gas and wire
the smaller units take very small wire spools
about 2.5 kg
the mid size units take 5 kg rolls and a full size will take a 13 kg roll
this is the cheeapest way to buy wire
then you have cylinder rental on top of that
for general jobbing work i would sugest you get a good inverter DC stick welder this will be of more use to you
and cost a lot less in the long run
suggest a cig cutskill 170 amp @ around the$400.00 mark
cheers Murray

i just bought myself a uni mig inverter 190. comes in 165, 220, and 250 also
very easy to use.

Id be getting a bigger unit, 190-250, as it will be alot more versatile, for an array of different projects.
inverter migs are smaller and just as powerfull, easy to move around, plus very easy to use.

If you're looking at 5mm plate etc then like Murray suggests a good Inverter DC stick welder is a very versatile and cheap to run tool. For barwork they work well and really suit the medium thickness plate etc. Mine is so small and light It'll probably do the trip to Jambo with me just incase

Cheers
Steve

I have a second vote for this welder, ive got the 190 and itll do everything you want, its a little dearer than you want (900) but its got a stick welder on it too, you can reverse the polarity for gassless wire, a really good welder
