Frank, I have a Dip Pak 200, it is a red one, that makes it pretty late in the production run. It has the Euro gun connection.The settings are voltage settings, in MIG amperage depends on wire size and wire speed. The chart You really need shows the settings for wire size and material thickness, There was a chart inside the door where You put the wire spool in when the machine was new. Dip transfer always uses low and medium range settings for wire from .025-.045. For instance using .035 solid wire 16 GA [about 1/16"] material requires #7 on the fine controll, Low on the range controll and 2.7 on the wire speed controll. 10 GA settings are 3, Med & 4.1 and for 1/4" material 7, Med & 5.5 all with .035 wire. These machines were built by Esab, I don't know if they can give You any information or not.
