Tig on aluminium is harder to learn. Did i read "easy" in the OP?

You can use mig on aluminium without a spool gun if you pay attention to various factors. If you want to do heavy wall aluminium you can pre heat and or use an argon/helium mix.

Love the trolley Justin , Not a fan of the Kemppi 180 mig though . Not being bias but they have a tendency to break the gun at the point where it attaches to the machine. A tip is do not pull it along by the gun.

Correct, although you can use argon only. It is a pain changing the liner though. Time consuming hence why i like the spool gun.

Does an ARC welder do stronger/better than a MIG welder for D.I.Y. sliders etc ?
I know a few old school engineers and boilermakers, and they say ARC is better, but surely these days, a mig would be up to the task.

:D that's because Old fellas don't know how to use a mig :p
There is no difference .
The wire rating or the electrode are the only difference GP . 16TC . 71 wire . gasless & your ability to weld :eek:

Picked up a Cig Weldskill 185 (Stick/Mig/Tig) and a spool gun today, on recommendation from one of the welders at work. Got the Argon from Bunnings ($200 deposit on the bottle, either swap and go or simply return for full refund).

Having never welded either Mig , with a spool gun or aluminium before, there will be NO pictures of my first welds (though a seagull did drop by to see which of his mates had diarrhoea)! Actually the last weld looked almost passable, but only had 15 minutes practice so far. Back to the practice bench tomorrow...


Thanks for the advice guys.
Cheers,
Mark

The contact tip is were the power is applied to the wire , a long stick out will get high voltage & low amps .
Keep the stick out at 10 mm & you will get a fair weld ;)

We are trade qualified I think we might know a little about mig .:p
Out dated Ol fools :p:p:p:p:p:p

Yer, there probably production welders. Never worked with very materials on a regular basis, hard to call some qualified.
Same shit day in day out, till there times up and there a qualified trades what?
No different to over educated uni students, know everything. Just have no real life experience, and don't know that text book doesn't cut it in the real world time and time again.
No substitute for expirence.. old or young.

The steel fabricator I use does everything with a MIG. They recently came out and did a heap of structural welding for me, on my house, two men two welders running all day. I fabricated the structure myself but don’t trust myself to do structural welds so erect and tack it all up and they glue it all together. Saves a lot of coin for me and don’t have to worry about the structural integrity :cool:
