#1 Tired of customers complaining that thier Lincoln Procut 55 is going through tips. THIS UNIT HAS A DRAG CUP, STAND OFFS ARE NOT REQUIRED! I know the manual says different, but that little dimple in the nozzle signifies a drag cup, the Domed nozzles use the stand off.

#2 Guys, don't use a CO2 regulator on a Argon bottle. The high pressure argon will eventually blow the seals, the flow meter ball will go up, but nothing will come out of the mig gun, or Tig torch, porosity galour..., then you call me in at $65/hr

# 3 The Lincoln Classic 2,3 ,3d and 300D may have a heat problem, that is, the operator is repeatedly having to adjust his heat. , can't long arc, and has poor auxillary power....Well, the culprit is the little square bridge rectifier, remove the lincoln version, and stick in a 35 Amp 1000V unit. Cost about $5US, Ohh and don't be turning the brush holders, this takes the unit out of polarity and Fuks up the rotor.
You want more power for capping, install a tach and pto lock. run the welder up to 2250, cap away and drop it back to standard. Please don't screw with anything else. Stock is a good thing!

#4 Sick of replacing the switch boards in the Miller 304 CV/CC with autolink, guys you have to wait at least 20 seconds after you place the unit in start, and before you weld. The unit needs the time to search for the correct voltage!
