Anyone own a Yeswelder ?

From your pic which is only half the machine it is set for .035 wire size and 25%CO2 AND 75% argon shielding and sync mode which is auto heat selection i think . Manual mig would let you set heat and wire speed manually i think . To find which knob is wire speed hold the trigger in and turn a knob if the wire comes out faster it is the wire speed knob and the other knob would be heat . There are probally other settings for stich welding and spot welding and looks like tig and stick just avoid them if only mig welding . this is all a guess from what i saw in your pic . good luck .
