Hay, i know its 400 posts about this but im welding with a 350 amp kemppi fastmig and i set up a new program. but the problem is that the program only asked me if im using 17 % co2. and i had to klick it. after putting 70s6 steelwhire.
it welds sputtery and it penetrates wary good. i think anyhow. looks like it on the weldpool. digs in to alot.
but welding uphill or downhill is impossible. uphill it digs in to the metal and it runs out like it doesent wanna bind the metal good. dripping big droplets straight to the floor.
its not clean metal. it has millscale but its thick. its 20mm to 10 mm
flat position it would run in a sputtery ''spray transfer'' way at 10.5 mprmin and 28.5 voltage.
i havent welded alot of really thick metal with 100% co2 but from what ive seen and red it should we fine. more demanding of accurate settings but it should be good. spessially on dualshield flux and hardwire to dirty materials.
welding 20mm and 10mm what setting has anyone else used.
ive tried 9m/per min and 24-25 volts but it just ends up being a thin concav weld. and with the z motion u can see the strings just going in z motion with barely anny heat or penetration.
Anyone think the actuall gas setting has somthing to do with it.
Im using 1mm hardwire with 100% co2 on a kemppi x7 fastmig 350.
going up to 1.2 mm help.
and for dualshield fluxcore wouldent atleast 25%co2 and 75%argona be better then 17% co2. becaus u need some active gas to make penetration.
Or can the 350 amp compansate for that with 17 % ?
Thanks for anny answers. i know its a wary known question to ask but i just couldent figure the setting out on a vertal uphil and downhil weld. it was hopeless. no metter what settings i put. and its fairly thick material. so i need the heat and the penetration without the whire just running straight out.
