Honestly you would be hard pressed to clip it with cutters and go straight to the weld in the short amount of time then cutting it off using a grounding clip next to the weld with both hands already in position. The further you physically move the tip the more shielding that is loss as well.

Very little movement and very little delay is optimum.
I'm not so sure about that. I've come to realize that the gas is in there a lot longer than I originally thought. If I stalled for a minute I used to trigger and cut to generate more gas even if it was already done so perfectly due to gas not in the line, but I soon realized it can sit there for a while and still have good gas.

On the welder I use at work, I once forgot to turn on the gas after turning it off for like 3-5 minutes and my first 3 welds were perfectly clean! Not sure If the welder at my house would do that nor do I want to replicate that scenario again but I think the gas is in there for a bit. If I worried about the gas leaving so soon I'd probably also wire brush off more the carbon crap on the welds between welds but I don't, but that is an option when you're twiddling thumbs letting it cool.

On the light issue, yep and that is why I just don't like the auto darkening helmets. I have used one of these Accustrike for years and I LOVE it wouldn't weld without it.

So do you cut it after EVERY weld? I like to cut the wire but not after every weld. I like to hot tack at times and you can't do that if you're cutting the wire. I will cut it if the wire length isn't what I want, there's a ball of metal on it, or the gas has been stagnent in there for a second.

All of these welds were cut off by striking the clamp; everyone..

It's a mix of thin metal and thick. The last is replacing the ends on 1/2" thick blades for a large bush hog on a large tractor which worked clearing fields all summer

All of this with including the blades with .023 wire:

nice work. I envy all that clean metal. Sometimes we get turds we have to shine and there's no good metal to weld too. Nothing like a nice clean well penetrated weld on clean metal.

He took those blades, put them back on a 100hp farm tractor and cleared 40 acres of treas and woods this past summer with these blades. I would say yes.
