How long you halt for determines the depth of the weld



This is BS. The electrode should always be in the leading edge of the molten puddle for the best penetration. Stopping or backing up is just adding filler but does absolutely NOTHING to increase or improve penetration. The "stack of (pick your coin of choice) look" is for appearance only. Look at any structural mig weld and you will NEVER see this type of weld.





Is that just your opinion or can you back it up with some documentation? If you stop while welding sheet metal it burns through immediately. That tells me your adding heat. On thicker than sheet metal welds I can see the back side of the metal show more evidence of heat (discoloration or ripples showing signs of molten metal) when I hesitate. Stalling in the puddle has to add more heat because of the longer time the puddle is molten right? I do use the push method BTW...
