    I'm doing something wrong I think I'm trying to repair the mounting ears on a old Muncie 4 speed case and I can't get it hot enough. I have the machine set on the high range and it just don't want to make a puddle hardly and it wants to blow the filler rod away. I've cleaned the area with a rotary file I know it is old and it still wants to boil grease out of the pores. The other question I have is where should the high frequency nob under the inside panel be set mine is on 100%.

    Aluminum Case M22 ...???

    What alloy filler rod..??

    GAS..?? ... Pure Argon or Argon Helium mix?? you are sure you are NOT running C25 MIG mix..??

    CFH gas flow setting..??

    Tungsten color ???... Red...Green... Blue.. or...?? & Electrode Thickness..?? 3/32...1/8... or..??

    AC balance not adjustable on the 330... it is 50/50

    Do you have a GOOD SOLID GROUND to the trans case...??

      Yes aluminum case was using 4043 filler 1/8" green tungston 20 CFH straight argon ground was right next to the crack. Where should the high frequency nob be set inside the panel mine is at 100%. Thanks for your reply

        HF intensity setting not very important as long as you are getting a nice blue arc across the sparc gaps

        when were the sparc gaps last cleaned and gapped... ??? ....probably good idea....

        have you tried welding clean aluminum with this setup... ??

          I think I have it straightened out one of the leads in the plug had backed almost completely out when I took the plug apart it was all the way out.
          I repaired the plug and changed to the largest cup I had and upper the argon to 25-CFM and it seemed a lot better. I cleaned the spark gap not long ago and set them. I bought this welder brand new in the late 80s and I'm the only one who has ever used it in a hobby garage race car stuff and so on so I'm am not of the caliber of you guys on here but I try thanks for the replies

            25 Cubic Feet per Hour (CFH) seems a little high (but may not be)

            too much can be as bad as not enough... excess flow can cause turbulence and draw air into the gas envelope...

            not saying it is too high... just that it might be..... so be aware

                How are those beads looking now..???

                PLS Keep us posted.... AND... Pics Pls

                BTW you might pick up some 4943... next time at the LWS.....much better than... 4043...for this application..

                http://www.maxal.com/4943_datasheet.pdf
                .
                Alloy 4943 filler metal was formulated to be welded with the same weld procedure specifications as 4043 and 4643, and does not depend upon dilution from the base metal during welding to increase the strength of the weld deposit, while maintaining the same weld characteristics and benefits of 4043 and 4643. Features/Benefits: - 25% higher UTS & 50% higher yield strength than 4043 in the as welded condition (typical) - Moderate/high strength (35 ksi typical) - Low melting temperature/high fluidity - Low welding smut and discoloration - Low ductility, formability, and lower toughness (similar to 4043) - Moderate electrical conductivity and thermal conductivity - Post weld fully heat treatable requiring no base metal dilution - Excellent corrosion resistance - Low shrinkage rate/reduced distortion - Low hot cracking sensitivity in most applications

                Welding 6xxx alloys, radiators and air conditioning components, general repair and maintenance, water and gas tight applications, post weld age, post weld heat treat & age applications, automotive/motorcycle frames, sports products - scooters/bicycles, general repair and maintenance, aerospace hardware, ladders and frames, alloy 356 castings, wheels, ship decks, furniture

                  +1 on the 4943. H80N got me hooked up with a sample. I had a lawn mower deck spindle come into the shop, it was for my brother. He busted a mounting ear off and wanted me to fix it. It was cast aluminum of who knows what grade. I did one side with the 4043 and it was ok. I did the other with the 4943 and liked how it wet in much better. Give it a try. I think it'll be useful, especially for repairs.
