alright guys, So today I invested in a mig welder, and got together some scrap metal to have a go with, one problem I found is that the welder was just spitting and spluttering everywher. seeing as I'm still new to welding, I assumed it was me that was doing it wrong. But I rang up a friend who does a bit of welding and he too has recently gone to a gasless mig welder and he has the same problem. any thoughts on anything we could be doing wrong? my welder is just a clarke 90 turbo, a cheap thing i got second hand. Any help would be great, thanks
