............ a welder.

Maybe a real good welder.........

Just to be clear about this - I don't know, but I might be a good guesser.

Shielding gas for welding aluminium.
Winner winner chicken dinner.

I bought a Spool gun for my Hobart 210 from Northern Tool. They're having a 40th anniversary sale, everything that fits in one of their buckets is 15% off. I crammed the spool gun into one and it deformed the bucket into an oblong thing, but I got 15 % off.

Anyone else have any experience with a Spool gun. Tips, tricks?

Does that mean there will be a aluminum trailer build in the near future?

No, but I am welding up some cracks in both of my white enclosed trailer fenders. An older white 16' v nose I bought in 2009 but has been parked for 3 years now. Painted it last weekend and replaced the brakes and hubs. Now I have to get the wheels blasted and painted and the fenders welded. Got to get it back on the road.

Yes, I have AC on both my enclosed trailers. Nothing like taking a break from the southern heat in a nice frosty trailer

I'll be sure to show some results of the fender weld tomorrow. This will be a first for me.

Wow that was weird. Gonna take a while to get used to it. You definitely have to run it with allot more stick out. Meaning the tip has to be allot further away from the material than steel mig welding. The sound is wayyy off of what I know is normal. Almost like a microwave struggling.

Only scrap aluminum I had was some pipe. Cut it in half and welded it back together. Ran a couple of push and pull welds on top to see how it plays out. Definitely need more practice.

So one fender done. Lucky I have many grinding flap disk's. The fender was different than the pipe. I had to essentially put in a bunch of spot welds to keep from blowing through then grind them flat.

The pipe was probably 3/8" thick so it was allot different. Because aluminum heats up so fast, your weld will look piled up when starting and look more flat when closer to the end. A bit tricky to find the mid point btwn too hot and not enough.

I have a 251 Miller with a spool gun for aluminum, I was going to tell you to have fun, looks like you already experimented! Once you get it dialed in yo good to go but it’s not always easy on dirty aluminum!

I did have fun but still trying to get the hang of it. I guess the hardest part is how quickly the base material heats up.
