Rev. A
electrical performance is based on a maximum weld head
distance of 50 feet (15.4 m) from the Model 307.
A System Stop Button is located on the front of the Power
Supply and on the Operator Pendant. Pressing System Stop shuts
down welding operations.
Weld Current Output. Current type is continuous or pulsed out-
put DC Straight Polarity for GTAW (TIG) welding only. The pro-
grammable range is from 3 to 200 amperes (± 1% of pro-
grammed setting or ± 1.0 ampere, whichever is greater
) while
maintaining a maximum average current of 150 amps at 100%
duty cycle. Programmable increments can be user-defined in the
weld program in units of 1 or 0.1 AP. Maximum recommended
amps (from a weld head template) can be programmed after a
warning of the "recommended limit" is displayed on the screen.
Note: Not all circuits are capable of delivering the rated
amperage. When possible, use a 220 VAC power source, or a
dedicated circuit for 110 VAC to avoid fluctuations in power.
