More 175 ?'sssss

admin

I am going nuts....tried to mig for the first time the other day..25 wire 100% argon ( I know what a waste) machine set to E and about 9 for wire speed.while welding, there is almost no arc noise, and I can watch the wire burn before it hits the metal......too small of wire or argon and no co2??while welding something thinner, machine set lower, crackles real good, with a nice looking bead and good penetration2nd.....Lots of burnbacks....on my last contact tip, meltin em like mad????Do I need to step her up to like .30 wire and get a good ar co2 mix..??Thanks for the help...Oh yeah, how thick can I really go with this machine on mig, it says 5/16ths with multipass fcaw, but the smoke and spatter is driving me ape@$#*Thanks to all.....and HAPPY NEW YEAR!!!!!!!!!!!!!!Miller blue star 2eLincoln 175
Reply:You need to go with co2 or argon co2 dude! heh, crackle away!!  Ive been using .035 wire and it does ok (lotsa splatter when I crank up the voltage though).  Im wondering if .045 will spatter less at the higher voltages...  HAPPY NEW YEAR tweet, whistle, belch....Various GrindersVictor Journeyman torch200cf Acet. 250cf oxygenLincoln 175 plus/alpha2 gunLincoln v205t tigLincoln 350mpEsab 650 plasmaWhen you can get up in the morning, Its a good day.Live each day like its your last.
Reply:Sound like you're exceeding the limits of the .023, in the settings department anyway. You were getting good results with .023 and thin materials, that's what it's designed for. Move up to .030 and you'll be tickled. Next time you need shielding gas go with C25. Better penetration.

Reply:Yeah, what Sandy said......E, on a tapped machine is almost full tilt and 9 is quite fast for .023. You need to throttle back, maybe try some .030 and go to C25 or CO2 for more consistent results. Good luck.Miller Millermatic 252Miller Syncrowave 200Liincoln AC-DC 225Victor O-A Set
Reply:CO2 is working awesomly with mine...straight CO2 and .035 wire... just great My Babies: HF Drill pressHF Pipe Bender3   4.5" Black and Decker angle grindersLincoln Electric PROMIG 175that´s it!
Reply:Hmmmm, plain argon with 0.025 wire and a 175A machine almost maxed out and no arc crackle noise?  And the wire is almost instantly vaporizing as soon as it leaves the contact tip and you are getting a lot of burn-back and toasted tips?Is the noise more of a hiss?  And how is the weld itself?If the weld is actually OK, then you -might- be nudging into spray transfer mode.Or you are just exceding the current-handling capabilities of the 0.025 wire.
Reply:I dont think its spray transfer..............the weld itself is not really a weld.....Miller blue star 2eLincoln 175
Reply:100% Argon would be handy for aluminum but not steel.
