Been welding since. 1982 never heard of waiting for the weld to cool and holding the tip there. A friend of mine is a welder at the ship yard, he builds ships. I'll ask him
Your ship yard friend is stick welding on ships mostly outside. He does not use any shielding gas.
I have a good long time/since hi school pipe welder friend. He is a absolute artist with a stick welder or any welder.
They use multiple types of rods with multiple passes. He welds up hi pressure underground gas lines all over the country now for like 25+ years now.
I learned a lot by watching him weld with a helment years ago on a drag bike. Tig welded everything.
If you can stick weld, then you can tig weld.
And it does sound like your solenoid valve is sticking, my 200 amp, 30 year old hobart mig does not have post flow. My 250 miller syncowave does.
Did you get it fixed yet?

I believe eastwood welders are chinese everlast or longevity welders. these are known to have stuck/sticking gas solenoids
the thing with eastwood is their warranty. use it. they certainly make sure you pay for it
pre and post-flow is generally a TIG thing. not saying MIGs don't have it, but I've never seen it. especially on a budget unit
Looking for 1975 through 1978 B body 4 door sedan sheet metal or parts cars - monaco, fury, coronet. Please let me know

Post flow might be used if you were doing aluminum with a spool gun - can't say for sure, I tig aluminum.
The spool guns I've used on aluminum mig have been post flow capable. You can see a difference in the termination suck back if you don't post flow aluminum with a mig.

Anyone can "bubble gum" sh!t together with a stick. Oxy acetylene takes two-hand coordination as well as heat control. Its the best entry to tig.
