welding aluminum with the spoolmate 100

[jhamm75]

I recently purchased a Millermatic 211, and also got the spoolmate 100 spool gun to try some aluminum welding. The welder works awesome on the steel projects i have done, but i cant seem to get the spoolgun to work like i want. I have a hard time getting a puddle to form, the wire seems to burn up before it hits the metal. I have tried the settings recommened on the machine, and tried extreme settings but it doesnt seem to change much. When i leave the wire out about 3/4", it seems to just dissapear when i pull the trigger. I used .030 5356 wire at first, but switched to .030 4043, which seems to be better in that i can sort of leave a bead, but still cant see a puddle or wire, just a glow. I am using 100 % argon gas. I am trying to weld 1/8" thick aluminum sheetmetals and sqare tubing. Any information is appreciated. Thanks.

Try turning the thickness to 3/8, & wfs to 100.

Not too familiar with that spoolmate but on a spoolmate 30 I think I ALWAYS start out with my voltage on 5 or so and keep my finger on the wire/amperage adjustment and start out with TOO much wire and then back it down. Also, make sure you are using 100% argon....NO C25....I almost always push the puddle with a spoolgun

This has been posted more than few times, try a search on the Spoolmate. It all comes down to a tip issue for this model.

It sounds like your wire feed is not high/fast enough. Also there is issues with the tips.

Wire feed speed check your manual what kind of wire speed they have on the newer units not as fast as they used to be don't ask me how I know.

Thanks for the replies everyone. Ill do a search on the spoolgun.

Use 035 instead and up your speed if your using the 30

I've had the Spoolmate 100 for a few years now and use it with the Passport Plus. I have always had good results, but find that the factory recommended settings are not always the best, so do some experimenting. Also, are you prepping the aluminum with a stainless steel brush and cleaning solution? That will make a big difference in the puddle. Also be sure to always "push" the weld, as mentioned before.
