I have found this post really helpful in explaining some of the basics. Many thanks
No mate. Clamp it tight to your bench and use the bench to suck the heat out and 1mm Alu is easily doable when learning.Am I heading for a world of pain trying to learn on ~1mm alu sheet? I have a massive pile of it lying around that I could practise on. Would I be much better off buying something a bit more substantial to start on?
By all means plug it in and get cracking with the pedalSo if the pedal is an available option would you say it's a good idea to learn without it anyway, at least to begin with?
Your dead right with the ac balance. You set the positive side on your machine.On my parweld...
Item 16 on the booklet for AC tig with no pulse for Ali .. I can only adj my AC balance from 15 to 50% and adj to the positive side..
so to say get 70% negative as I believe Richard suggested does that mean I set this to 30% on my machine.. if I want 60% to the neg side I set it to 40%..
Also to set the initial current No9 on the booklet, it says I can adj the value from 5% to 15% of the main welding current but, when I try to adj the figure is set in Amps rather than a percentage ? So I guess? If I want 10% background and main current is 100amps I set it to 10 amps.. seems a daft way to set it imo if I'm correct..

Thank you as always .... x
See above hope it helps.How do you set up the regulator? 6-8lpm
What is the switch on the torch for?
Starting the welding process when not using the pedal.
I'm guessing gas, pure argon
in which case is it just a matter of pulling the trigger just before the weld and releasing the trigger just after? You either use the switch on the torch OR the pedal. Not both.
How far should the tungsten protrude from the torch?
My preferred are
3mm outside corner
5mm butt and lap
