          Here’s my original question. If anyone has answers I’d love to Know!!

          Good day! I’m looking to weld some larger aluminum projects and was wondering what kind of aluminum mig options are out there for my Dynasty 280 dx welder with the Extreme 12vs suitcase mig addition. Looking to weld 3/8” and possibly 1/2” material along with aluminum HSS tubing. Thanks!!

            I wouldn't even bother trying, its not going to work well at all. Better to get some helium argon mix and use your tig welder as a tig welder.

              Material thicknesses like that are usually because it needs to be strong. I don't think you want to sacrifice the joint quality. If this is a paying project, invest in a bigger machine.

                That Dynasty supports pulse, correct? If yes it will work OK, the biggest issue with MIG welding aluminum is keeping the heat right. Without preheating it goes too cold->just right->too hot pretty quickly, with preheating it'll go just right->too hot. Pulse will help keep the temperature in the just right area longer. I don't know if you can put a spoolgun on the 12VS, if you can I would go that route. I've MIG welded aluminum with a Teflon liner and while it works, you've got to keep the gun cable very straight because the slightest restriction can cause the wire to bunch up at the rollers. Do you have a lot of aluminum welding to do? Unless there's a lot of production, I would second the suggestion to just TIG it instead, you've certainly got a good machine for the TIG option.

                  The pulse settings are for Tig not mig. About all you can do is put the machine on stick dcep and use the 12vs on cc mode. You'll need a teflon liner as stated. Its really not going to work well if it even works at all. You have a great tig machine but its just that, not a mig welder. If you dont have a ton to do then you could just use the tig welder. With some preheat and helium mix you should be able to get by. If you have a lot to do then you really need something like a millermatic 350p, lincoln power mig 350mp etc.

                    Miller makes a Dynasty 280 with the mig feature now.
