MIG with argon

[BigRAWesty]

Here is the video(s) where I did the 0.6mm wire without gas(pure argon)
This is amazing guys. I'm getting "better"(kinda) results without pure argon or any gas for that matter.

When I moved the gun, there was too much splatter(even though I moved and kept the gun almost touching the base metal or actually touching it with the nozzle).
The bead to the left is where I moved the gun(but didn't record in on video).
The 'bead' to the right is the one from the video where I got better results than with pure argon.

Now, I'm beginning to wonder whether there is a need for shielding gas at all, considering how bad the beads were with pure argon.

The weld tack I produced by keeping the gun on the same place was pretty strong. I couldn't get it off by hammering on it hard, whereas the pure argon shielded beads were able to remove with a flat screwdriver(without even hitting it).

I'm pretty intrigued by the above result.
I think it's about time I try either with pure CO2 or argon/co2 MIG mix.

Flux core (gasless) is made to be run without gas. It is literally an electrode on a roll. The flex burns and produces the correct gas to shield the weld pool, by using gas your messing with the flux gas and stuffing it up..
You can buy flux core that needs gas aswell but that's usually very heavy industrial and outside stuff..
Flux core needs to be treated like a stick welder.
You drag the slag, so pull the hand piece with flux core not push like a solid wire..
Imo invest in a mig shield gas.
It's chalk and cheese and really I think your trying to push shit up a very steep slope with Argo and that welder.
