Burnback issues are nearly 100% wire feed problems.
Pulse MIG is a non-contact process, which means the welding wire never touches the puddle.
The electric flow and arc voltage need to stay and run in constant tension. I am going to TRY to take it apart and see if any loose connection. MIG pulse welding is also much easier for beginners to grasp. After the machine is turned on, the first step is selecting the process with the top buttons. As soon as it touches the wire heats instantaneously and forms a globule, which "pinches off," flowing into the puddle and creating a small gap between the puddle and the wire.
