Followed guides on this site and practiced alot. But my skill is not very good. I have a SIP 100 Mig welder, I've messed around with power settings, wire speeds and gas flow but all without great success. Is welding really so hard or is it just me!! I seem to get alot of splatter (pigeon poo!), blowing through, wire burning back! Is this all really down to meor could it be a faulty welder? What checks on the welder can I do? Advice and support will be gratefully be recieved!!!!
