ENGINE DRIVEN GENERATOR
The Invertec® V311-T AC/DC TIG can be operated on
engine driven generators as long as the 230 volt auxil-
iary meets the following conditions:
• The AC waveform peak voltage is below 400 volts.
• The AC waveform frequency is between 45 and
65Hz.
The following Lincoln engine drives meet these condi-
tions when run in the high idle mode:
• Ranger 250, 305
• Vantage 300, 400, 500
Some engine drives do not meet these conditions
(e.g. Miller Bobcats, etc). Operation of the Invertec®
V311-T AC/DC is not recommended on engine drives
not conforming to these conditions. Such drives may
deliver unacceptably high voltage levels to the
Invertec® V311-T AC/DC power source.
