In one photo it looks ok but the rest appear to show brass covering the inside of the gas holes , the tip is copper so it's not the tip , did you check the holes Dom or can you take a photo at a better angle of the gas ports .
@GQtdauto, this are the photos of the MIG tip/tip holder/nozzle holder, close-up.
These are the photos of the fitting on the regulator that I had to swap over.
As you can see the original one(silver one) has no O ring.
I added pictures of the inside of the gas bottle fitting. It doesn't look like it's damaged.

If you undo that gas defuser (yellow bronze section) you'll find the mig liner (long coil looking thing) runs right up to the base of the conductor tip (Brown bit on the end with the wire coming out), so the gas holes may look blocked, but it's totally normal.

And while were on bottles (which look fine), you only need to crack the bottle open, not 100% like you did in your video.
When on opening a bottle it's only ever 1/4 turn, 1/2 max if I'm feeling generous or bottle is getting empty..
The pressure these bottles are under you don't need much..
Mate Ben is right what are you doing way too fast and erratic with the hand piece , try pushing only and slow down .
Yeah, that is true. But, it won't make any difference even if I move slowly and keep the nozzle touched or almost touched. The welds come out bad regardless.
