They're great aren't they! So controlable. We've just (well last year) purchased one. The last couple of weeks i have been using it
for my A-Level coursework. Very useful! Being the only type of welding (other then brazing) I have ever done I think i'll probably find it hard
to use gas/mig/arc now...
Cheers,
Andy

Having never used MIG before i couldn't compare. However I can say that having only played around for 25-30mins I was able to get decent, neat
welds. However, I may need 'just a little' tutition before I go anywhere near Aly!
Hope this helps,
Andy

I had a go at TIG welding last year at uni. I started on steel, got the hang of it in about 15mins then went onto ali. (Remember you need an AC TIG
welder to do ali to pull the oxide off). Ali isnt really any harder than steel, you just need to be a bit more gentle.

Am I right in thinking that TIG is like gas welding but with far more control of heat?
Should be easier to maintain a suitable molten metal pool, shoudn't it?

Even easier with a foot pedal, like a singer electric sewing machine!
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Mark...thats what i was using. Its so easy once you get the feel of the pedal you are away, just small adjustments to keep the molten pool the right
size. TIG is great. I think it generates more heat than MIG (as its slower to do) so you could introduce more heat distortion problems in the
chassis....though i stand to be corrected on that!

The gas cools the surrounding area so the distortion is minimised

Thefel of the pedle?
Is the peble ON/OFF
Or variable output, push harder for more current.

The pedal is like the accelerator in a car...harder you push the more current you get.
