Cheers Weldy, but it wasn't meant to read 10mm ally - ally sometimes, but other (steel) upto 10mm! What exactly is around the same money? Have PM'd you weldy.
What if the ally use was dropped gents and it was a DC tig GavUK and others?
10mm al will warrant a big machine with lots of D/C Iv been on 1/4 fillets on box all day and am glad iv still got the 500amp kemmpi in the corner, al is a frustrating process (altogether) but especially with a machine thats lacking....
If its occasional and you have access to preheat then 200 amps minimum is needed, as temperatures drop this time of year it sorts the men from the boys.....
Keep up, Snowy!
