Spray arc...

You can do most and build most anything within reason with a Hot short arc. I am surprised that there is so much discussion on spray transfer. Yes it's a smooth high deposition way to weld with low spatter providing you stay in position but. With proper technique and parameters you can do just fine with short arc. I'm not saying you should forego Spray at all. You should learn it but. If you want to get into the current millennium you should at least be curious about Pulse and Twin Pulse and what it can do for you. As mentioned above, I too have a Smith Mixer and enjoy the ease of switching from short arc gas to pulse gas as well as higher 90%+ Argon gas for Stainless. Learning to weld is a one step at a time process but if ever you want to cheat and look at the last chapter of the book before reading all of it, You'll be looking at Pulse and or Twin Pulse. They Trump Spray any day. So much fun to be interested and learning this wonderful productive skill. Good Luck going forward !!

I do all this with a 40 year old Linde SVI 400 cost me $300, I run it off my rotary phase convertor at my farm shop.

Twin pulse would cost me how much ?

And IIRC the bog standard Lincoln 255c can go spray with .035 wire.
Kinda handy to occasionally weld some thick stuff that comes into the shop
without spending time to change wires, or buy a $6k machine eh ?

I work in the heavy fabrication industry, get into several similar shops, no one I know is running twin pulse.

Spray or gas shielded flux core is what I see everyday.

Yes sir, Process and application will vary all over the country. Pulse and twin pulse are newer processes that will be the norm in a few years. Kinda futuristic sounding arc as well. I do remember the old Linde yellow face machines and later the white face, Many still in operation where I live. You got yours for $300. Can't argue. Probably last another 30 years or more. You could get into a nice Pulse/Twin Pulse set up for between 4-8K depending who you bought it from. What a deal ayy?

Spray arc.

Mainly used in high-speed production work where there's a large volume of weld to be done. So it's a process to get more weld down, in less time. Did I get this right?
