My thoughts are to continue practicing heat control till I tack on demand
Then I can worry about the heat control on my welding
I believe my heat on tacking to slow or to close. I make a lot of kisses on my attempts
If I can gauge the lightness of the heat to just blow those two pieces of liquid together. I tend to heat on side or other then make kisses.

Hi Paloma,
Yes, larger coupon.
Steady hands ... one hand can support the other. Or, I use a smooth wood broom handle to support my wrists. Parallel to my front. Above the work. Slide along to get the feel of it. Maybe some wax. Then - weld.
Practice, practice .... then tacks come on demand. (but- metal has to touch... molten metal cannot levitate across gaps.)
Max heat is when torch is vertical to the metal and right on it = max heat. Then as the torch angles, the heat glances off....heat goes down.
Last, left-right. But on center is equal heat. Hard to see, but move quick when one side melts first. This is a quick fast process. Get ready, get on top, and your welds can only get better.


(Your welds are looking better.)
