VOLTMETER
(Factory installed on model Codes above 9218)
The 40V DC analog voltmeter is mounted to the front control panel of the
When switched to the HI range position, the constant wire feed speed (CV Wire Feed Mode) is set on the outside (black) dial range calibrated for 50 to 700 in/min.
The volts marks around the HI range calibrated dial indicate the minimum arc volts required to obtain the indicated HI range wire feed speeds. For example; if wire speed is set to 400 in/min., a welding procedure arc voltage of at least 17V would be required to obtain the 400 in/min. wire feed speed.
