Definitions Of Inputs And Outputs
Inputs
A - Closure to D starts the weld cycle. Opening closure stops weld cycle. During 2T operation, a momentary closure (greater than 100ms, but
less than 3/4 seconds) starts and stops weld output.
B - Closure to D turns on gas. If a preflow time is entered, the preflow cycle will time out before arc initiation. If a post flow time is entered, the
post flow cycle will time out at the end of the weld, even if B to D closure is opened.
C - Closure to D must be maintained at all times. If the closure between pins C and D is broken, an output disable occurs, Postflow begins to
time out, and HELP 13 will be displayed on the meters.
Outputs
Outputs are isolated open-collector transistor which are able to conduct at least 60 mA of current and 27 VDC peak.
Final Slope - output is on when in Final Slope.
Pulse Lockout - output is on when in Initial Amperage, Initial Slope, Final Slope, Final Amperage, during background time, and when the pulse
frequency is less than 10 Hz.
Arc On - output is on when the contactor is on and amperage is greater than 5 amps, or output voltage is greater than 5 volts but less than 50
volts.
