Hey Bob,
i would suggest you get a bottle of gas ,argon-co2 /75-25% for steel .Inner shield is ok but too much spatter and smoke.Mig wire should be adjusted for max penetration and smooth arc like bacon sizzling.get a good grade of solid wire the right gauge for your parent metal and amperage.watch the grade ..no junk..Destruct test some welding coupons before real stock is used and you should be set.Go to miller and lincoln sites for some good info.Gas fed mig welds should look real nice with min spatter...PS. did you consider tig? Jumping wire could be dirty rollers,bad feed pressure,wire drag, too low amps,liner build up...you name it..all takes practice.Hope this helps.
Alex and I use anti spatter and nozzle dip...helps.
