Hi, I have never done any type of welding in my life but I have bought a gas/gasless Cosmo 130 mig welder to weld some steel plate onto the chassis of my car... Anyway the problem I am having is that i put the gun against the metal to be welded and it sparks a lot but doesnt seem to be leaving any weld in a seam or anything, I just get little balls of weld all over the place and the metal glows orange! I have looked at the tutorials on this site. I am using 0.6mm wire (that was already on the welder), what exactly does the gas do? I bought a gas bottle but the welder has got no regulator so I was unable to connect it. I have tried setting it on low and high and god knows why there are 3 switches to control the voltage? I have changed wire speed to slow aswell... I have also tried holding the gun 5mm from the metal as suggested but it doesnt spark, I have to hold it right next to the metal!!! Is there a good book I can buy to teach a complete idiot like myself? Thanks. I saw those pictures on the tutorials with the steel plate where the weld goes right through... Mine doesnt do that!!! just little balls!!!
