How Much Should a MIG Welder Wire Stick Out

Electrode or the wire stick out should be about 3/4 of an inch. Less is OK but a much longer wire stick out won’t allow the shielding gas to do its job properly. I do want to mention that the shielding gas flow rate needs to be right for the stick-out. Too much gas causes turbulence even if the stick-out is just right and too little gas does not provide enough shielding gas. It is a balancing game that requires judgment for the situation. Just keep your stick-out between ¾ of an inch at the max to ¼ of an inch at the bare minimum.
