13AP1:3 Gas valve

The gas valve is controlled by the microprocessor. In normal operation the gas valve opens
when the start signal is activated by the robot. The gas valve can also be opened by a
separate signal from the robot.

13AP1:4 Motor driving / braking

Schematic diagram of the motor drive stage. The print numbers refer to different board prints.
See component positions.

Driving

The motor is powered from the sm60 V supply. Pulse-width modulation of transistor
Q4 varies the effective motor voltage. Pulse frequency is 39 kHz, and the maximum
conduction period is 97 % of the pulse period. Freewheel diode D27 provides current path
during the pulse off periods.

The feed roller speed at the maximum wire feed speed of 25 m/min is 273 r/min.
