G'Day,
After contemplating for ages I decided to get some bits and pieces and try TIG-ing up some copper. Before I knew it I had spent ages fiddling and working some things out. It went OK but I have a lot to learn that's for sure.
As you can see I got carried away and went straight down to 1/2" off the top of the column.. Thought I would try and see how it goes... I realise most plans drop down to a section of 3/4" first. Plan on trying to tig up a 36" Leibig (1/2" inside 3/4") and have a compression joiner between it and the column for dismantling.
Amazed at how much heat it takes to saturate the piece (especially once the piece gets a bit bigger) and how hot it gets. Up the amps to get a puddle quicker and you had better be ready to back that pedal off or the house of cards comes falling down in a big way. Kind of similar to Ally in that way I suppose.
Also tried welding Copper to stainless (keg flange adapter fitting) but this ended in disaster. I'll keep trying after I get some advice from those with skills.
Anyway, thought I would share. It is nerve racking as copper is so expensive I loathe to wreck any. But you can only learn so much practicing on scrap.
Anyone who has skills or advice, I would be extremely grateful for your input and comments. You wont offend me, I know my work is no oil painting!
Regards,
Luke
