Thread: Help with spoolgun aluminum welds

    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 Click image for larger version.

    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.

    I will get the starting range my son uses. We do 4043 all the time and look great. No spatter. We have never got it to spray with aluminum either.

    Any luck finding those settings? Do you use different settings for 5356?
    The forum has that jumping cursor problem again where midway through typing a sentence the cursor jumps to the line above.

    Thank you for the tips but 99% of my spool gun work is .090 aluminum sheet and tube. I need pulse to prevent heat buildup from burning through.

    When I weld .100 aluminum I still use 4043 3/64" (.047) wire at around 16 to 17 Volts 230 to 250 amps/wire argon 20 to 22 CFM and it is close to spray welding. The pulse is nice but I don't have that feature.

    He said the main thing is he has to run the AMP/speed knob all the way up. Also little over 1/4" is all he can do wit 4043 .030
