mig welding 'burn back time'??

If burnback is set incorrectly you either have a long wire sticking in the cooling puddle when you release the trigger or the wire burns back up to the contact tip and sticks in the tip. When you release the trigger you want the wire feed motor to stop feeding then a very short time later the power/welding current should shut off. Some machines have the burnback adjustment on the front of the feeder. When it is readily available it becomes a magnet for every fool's attention. After that fool has used the machine, of course... it is your turn to use the machine. Randy

When you let off the trigger, it keeps welding for an instant with the wire rollers off. This keeps you from getting the wire stuck in the puddle every time.

Guys,

That was a classic example of "Zimmer Prose". > If burnback is set incorrectly you either have a long wire sticking in
