So have had 4x3h sessions now at college as a complete beginner on a MIG course
First sessions were using a Lincon 305 with the seperate wire feeder on top, managed to get the hang of the setting and was managing not too bad welds. Had a nice sizzling noise during the welds and when moving back towards the puddle the noise would increase slightly compered to pushing into fresh metal.
Last night I was on a Lincon 231 machine and really struggled to get the same result as I had the previous sessions. Spent about an hour trying to alter the speed of the wire and the voltage, but took ages to get the welding like I had been doing before. In the end I was getting welds that werent as good as I had been doing but were better than when I egan the session, the one thing i did notice is that the welding was very loud, as though I had the power way too high, so I think that was confusing me and as I was decreasing the power I was getting the wire to hit the back of the pool and intermitant arc.
Should all MIG welders have a similare sounding sizzling sounds or are some just very loud and thats just the way they operate?
