START: command signal for powering the electrical arc.
0V = arc OFF
24V = arc ON
PIECE SEARCH: command signal for activating the piece search mode.
The piece search test is active when the system is not welding (load free voltage at output).
0V = test inactive
24V = test active
WIRE BACK: wire retraction command signal. Wire retraction speed is 1m/min and retraction
time is 1s.
0V = wire back inactive
24V = wire back active
GAS TEST: command signal for opening the gas circuit solenoid-valve. The solenoid-valve stays
open for the entire "command active" time.
0V = test inactive
24V = test active
AIR TEST: command signal for opening the air circuit solenoid-valve. The solenoid-valve stays
open for the entire "command active" time.
0V = no air flow
24V = air flow
WIRE FORWARD: wire extension command signal. The extension speed corresponds to the
value set by the operator. Wire extension stays active for the entire "command active" time.
0V = wire not extended
24V = wire extended
RESET ALARMS: reset alarms command signal.
0V = no reset operation
24V = alarms reset
