I hate to throw money at problems but I could not make the other spool gun function correctly. It sucked air and had erratic wire feed speed. I tried and tried but couldn't correct those problems.
I purchased the same basic spool gun from Mundaka but it has a much nicer one piece lead, same as a regular mig gun and uses common Tweco front end parts. I changed them to the screw on 23 style that I use on my Profax mig gun.
My skill isn't there yet and I'm guessing at pulse settings but I at least have a starting point now. I also learned from an old Esab chart that 5356 needs lower voltage and higher wire speed than 4043.
Here are a couple of pics I took about two months ago when I got the new spool gun and started testing again
I've been working a lot more lately so I haven't had much testing time but I think I'll catch on quicker now that the spool gun problem is solved.
If anyone would like to share pulse settings for .090 aluminum I'd love to test them. I might even learn to weld in a straight line.
