  • mig dip transfer welding or short circuit welding

    I am an authorized miller service agent. Today a customer of mine brought in 2 welders: a mm252 and a deltaweld 302 with feeder. They are saying that the welder works fine in spray mode but doesn't work in short circuit mode. I have checked the Operational manuals and service manuals of these 2 units and cannot find any thing in there to change the welding characteristics other than voltage and wire speed. According to a technical manual I have you must be able to control the reactance to do this. Any thoughts? The customer is getting spatter and doesn't like it. I guess they are turning the voltage down to try to get into short circuit welding.

    What shielding gases and wire sizes are they using? Are they trying to do both processes with the same gas and same wire size?

      That looks like a shielding gas problem to me, but I'm not an expert.

      Short-circuit always splatters, at least in my experience...

        Might check and clean the holes in the mig guns gas diffuser.

          Looks cold too. What settings for those welds?
