Hi, I'm a total noob here and hobbyist welder for a few pet projects of mine. I've read lots of articles, which have helped get me through most my past welding projects with good results, but with the vast amount of information available here its difficult to pull the good advice from the bad required for my new project.
I'm looking to weld a 12mm mild round bar too a 6mm plate (which is mounted to a 10mm jig plate) and also 12mm round bar to 3mm plate (NOT mounted to any jig plate). I know I will need to buy a new welder for this project, but the advice given will help determine which welder I eventually purchase. There will be lots of awkward angles to contend with when welding as the project piece is built up in the jig, so I don't know if big shrouds and long electrodes are the way to go or if there are other solution which would work better ? Its not a straight forward weld for my level of experience and I also want the welder to be AC/DC Tig welder for some aluminium projects too, so I'm not interested in a MIG welder at all.
So with that in mind, what would you professional ladies and gents do welding 12mm round bar to 6mm plate? I know it requires a bit of power, but I don't have access to 3 phase, so this limits my overall amps. What sort of setting, electrodes and rod would I need to make a sound single pass weld ? And also the same question for the 12mm to 3mm plate ?
I've done some experiments with my current, very crappy Clark inverter at around 120 amps, it welds ok, but I know I'm putting way to much heat into the project, which makes controlling the pool very difficult and it's distorting the material way more than allowable.
Thanks in advance.
