Hi guys, been a long term lurker on this forum, also done quite a lengthy post on an old car I was replacing both sills on with sheet steel, without the help from here I probably would've thrown in the towel halfway through as I felt in over my head for a first project but all the comments and advice from here was a massive help so guessing you guys can help again.
Just Bought myself a new Rtech acdc 160amp tig welder, the first job I had to do was extend the exhaust leading to the back box on my Integra which was stainless. Started practicing on a spare bit of stainless exhaust and just made a mess to be honest and got me thinking this isn't how it goes down on they YouTube vids I've watched lol. I didn't have a clue where any of the settings on the welder should be so just kept playing away. Eventually got the machine dialled in to where it worked the best for me, got the exhaust done but not to the standard I would've liked so I'll probably do it again once I've practiced a bit more.
But today's job was just horrible and couldn't seem to find a sweet spot with the welder. I needed to make some intercooler boost pipes for my Integra (2mm alluminium) tried 1.6mm red tungsten and it just kept balling the tip so stuck in a 2.4mm and it was slightly better. My biggest problem was butt joining the pipe, the edges would burn away almost instantly making it impossible to even start a puddle, also most of the time the arc was causing violent splattering and when adding filler it was burning green and splattering. The welds were hideous, all porous and burnt, any ideas where I'm going wrong? I got a full bottle of argon today so there's plenty of gas, waiting on a flow meter coming so I can regulate the gas better. When just laying weld on a piece of metal I seem to get an almost acceptable weld however can't do a joint without the edges burning away. Any help is massively appreciated, even just a starting point with the settings on the welder, and sorry for the massive post
