Definitely helps buying steel using company accounts etc. I buy all my stainless through Stirling's in Bibra Lake. The price is ludicrously cheap due to the volume of purchasing we do off them.

Really keen to see your results with lower amps. You're doing good welds so keep at it. Got a few of the coded welders in and out most the day so will grab one of them and show them your posts/pics and report back to you with any advice.
