advice needed to improve mig weld
I read MARTINSR's great FAQ for mig welding but have a couple questions to try to improve my skills (or lack thereof). With my new Miller 175 I seem to get a lot of spatter in the nozzle. Is this a sign that the weld is crawling up the wire - and thus the speed is too slow or is it evidence of some other fault? I've tried adjusting the voltage and speed up and down a bit but still seem to get a build up in the nozzle. BTW I'm using a 25/75 mix of gas and .030 and .035 wire on 1/8" to 1/4" steel.
