My company has purchased a new Lincoln welder to MIG stainless steel. We are using .030 t304 wire on sheet metal (14 gauge). My question is this; should I be using argon/ox mix instead of the tri-mix that I am using now? I am having spatter problems. The globule is blowing off of the tip of the wire onto the parent metal instead of in the puddle. I'm using pretty low heat, about 35 amps. Anyone doing this successfully? Thanks.
Reply:for stainless i use 98/2 argon /co2 some welders like the try mix i dont think its all that are you shure you have the feed and heat set right?ChuckASME Pressure Vessel welder
Reply:be sure the polarity is right and it's not set for fluxcore.DennisThermal Arc 185-TSWMillermatic Challenger 172VictorO/AAtlas Craftsman 12 by 24 LatheEsab PCM-875Wholesalem Tool Mill-Drill
Reply:Actually the machine is preset for wirespeed and voltage. Then from there you can tweek the volts and waveform timing. So that tells me the feed is set right.
Reply:lowbflat, check your polarity (+), tri-mix should work, the preset is not always the best setting for every application, you need to tweak or completely experiment with other settings outside the preset, it will work.PM300?Short I assume, not spray?
Reply:Short I assume, not spray?Sorry...pulse mode, ok.
Reply:Just purchased it, same machine as PM300 with a few more wave forms built in i think, in pulsed spray mode using tri mix or Argon/Oxygen not Argon/CO2 you should have no problems at all. if you continue call Lincoln and ask about a custom wave form for your process they have been most helpful to me in that regard, also not sure if the 300 has the power mode if so try using it in conjuction, it is designed for low output stability Fire doesn't burn a good Christian !
