what does this mean when your mig welding and right when you start to weld, it starts popping and crackling. Is the wire coming out to slow or fast. I would think fast, but my wire speed is pretty low. Let me know guys. -Nick

 

A little bit of spitting and sputtering at first is normal, as the arc has started, wire is hot, but there's no puddle there yet. Tig doesn't give this because you get an arc and puddle prior to adding wire.

 

sounds normal....... if it pops at first like ^^^^ said

you will now if you are going to fast because the gun will kind of jump around a lil in your hand because the wire is feeding too fast and pretty much tapping on the metal before it melts into the metal........... maybe that made sense

 

ahh i see. Yeah it was doing it at first along with while im welding. I turned the heat up on some of my last welds and now the welds are 100% penetrated. Usually when you turn the voltage up do you need to turn the wire speed up to, to accomidate each other? Let me know guy's. -Nick

sometimes you can get away without speeding up the wire but generally, yes you will want to speed the wire up when you weld hotter....... if you just adjust up the heat without more wire you will be able to see that the wire is not feeding fast enough..... the wire wont weld constantly it will zap then stop then zap then stop and so on because the wire have to catch back up to the weld........ when you see it through the helmet you will understand what im talking about

that is kinda hard to explain but trust me you will know if you are going too slow
