Hi. I'm trying to set up my machine to mig aluminum. The welds its producing look more like rabbit turds than anything else. Machine is a MillerMatic 211 with a Spoolmate 100, set per the manual at 5/70. Harris 4043 wire. Argon gas is set at 19cfh. I know the gas is good because I tig with it. Material is 1/8 Al scrap. Hopefully some of you will drop some knowledge because im goin nuts trying to figure this out. Attached ImagesBobcat 22512VSCST-280Millermatic 211Hypertherm Powemax 1000Victor O/A
Reply:Your argon may be good, but are you sure that it is coming through the spool gun line? That looks like a classic case of no argon to me.Miller Syncrowave 350Millermatic 252/ 30A spoolgunMiller Bobcat 225g w/ 3545 spoolgunLincoln PowerArc4000Lincoln 175 Mig Lincoln 135 Mig Everlast 250EX TigCentury ac/dc 230 amp stickVictor O/AHypertherm 1000 plasma
Reply:There is definitely argon coming out of the gun, but I have no way to measure how much it actually is. Ill go out and double check the gun now.Bobcat 22512VSCST-280Millermatic 211Hypertherm Powemax 1000Victor O/A
Reply:Are you pushing the weld puddle?
Reply:I assume with the setting of 5/70 you are running on 230v power right?.No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
Reply:There is no puddle, it just blobs up from the start. I just went and swapped my 211 back over to the regular gun, and ran some beads on steel. They came out fine, which tells me the machine has adequate gas flow.Bobcat 22512VSCST-280Millermatic 211Hypertherm Powemax 1000Victor O/A
Reply:Yes, machine is on 230v.Bobcat 22512VSCST-280Millermatic 211Hypertherm Powemax 1000Victor O/A
Reply:It really looks like you're lacking gas. What kind of stick out are you using?IW Local 580 NY, NY
Reply:Ok, I kicked up the gas to 30cfh and moved the butt joint off of the bench, and attached the ground directly to the material. Looks like it worked. Attached ImagesBobcat 22512VSCST-280Millermatic 211Hypertherm Powemax 1000Victor O/A
Reply:Stickout is 1/2 to 3/4. Is that soot normal? And fyi, I posted this on the Miller forum as well.Bobcat 22512VSCST-280Millermatic 211Hypertherm Powemax 1000Victor O/A

Reply:Just a reminder, most of the hardware rack aluminum stock is crap aluminum....Not all of it but I have had problems with some......Better to just shear off strips of material you know is a good grade if you want to practice, or go to a fab shop that stocks 6061aluminum.....
