Reply:Pretty much any dual shield .045 will be fine.thermal arc mst400, va4000 feeder, lincoln 175 min, victor torches, miller s32p feeder, air arc k4000 for work.
Reply:I use heaps of ESAB 7100 Ultra-.045 and use mostly 80 AR 20 CO2 gas, but sometimes 100% CO26 Miller Big Blue 600 Air Paks2 Miller 400D6 Lincoln LN-25's4 Miller Xtreme 12VS2 Miller Dimension 812 4 Climax BW-3000Z bore welders Hypertherm 65 and 85Bug-O Track BugPair of Welpers

Reply:any dual shield flux core. i run straight co2. but for aything that is going to see high amounts of stress, i would still stick it. but thats me.....
Reply:Id rather stick-it myself, but economics dictate fluxcore. Working in the mining industry, dualshield was the go to consumable. You can really get allot welded deep & pretty with that stuff in a hurry.

Reply:id use a 65 or 70 tensile flux core then ..... you can run a mix but straight co2 is cheaper
