DESCRIPTION OF OPERATION

13AP01 Control Board

The sections 13AP01:1 to 13AP01:13 refers to the wiring diagram in the chapter "WIRING

DIAGRAM".

13AP01:1 Power supply

The power source supplies the wire feeder with 42 V AC. The wire feeder's power demand at

maximum load is 6.0 A.

42 V AC is used for the welding torch trigger switch, the power supply to the gas valve and

for the current relay.

Rectifier BR1 rectifies the 42 V supply to 60 V. Capacitor C28 smooths the voltage, which

then supplies the wire feeder motor.

Transistor Q8 is a pre-regulator which reduces the voltage from 60 V to 20 V. Q8 is

current-limited to about 200 mA. If the 20 V supply drops below 13 V, the wire feed unit

stops.

VR1 and VR2 are 5 V and 15 V voltage regulators respectively.

13AP01:2 2-stroke / 4-stroke

2-stroke

When the switch 13S3 is open, 2-stroke control mode is selected. This means that closing

the welding torch trigger switch starts the wire feed motor, opens the gas valve and closes

the power source contactor. Releasing the switch stops the motor, releases the contactor and

closes the gas valve.

DESCRIPTION OF OPERATION

0463 394 001

- 14 -

4-stroke

When switch 13S3 is closed, 4-stroke control mode is selected. This means that first closure

of the trigger switch operates the gas valve, with the wire feed motor starting, and the power

source contactor operating, when the trigger switch is released.

Closing the trigger switch for the second time stops the motor and de-energises the contactor

in the power source. Releasing the switch closes the gas valve.

13AP01:3 Start / Stop

The welding torch trigger switch is supplied with 42 V AC. Closing the switch activates

optocoupler IC1, causing the voltage across C35 to go low.

When the wire feed starts, the power source generates welding voltage. If this is not followed

by a flow of welding current within three seconds, the power source shuts down the welding

power supply, although wire feed continues until the welding torch trigger switch is released.

13AP01:4 Current relay

Current relay

The current relay operates if the welding current exceeds 20 A.

Creep start

The creeps start function is always activated.

DESCRIPTION OF OPERATION

0463 394 001

- 15 -

13AP01:5 Motor driving / braking

Driving

The motor is powered from the smoothed +60 V supply. Motor speed is controlled by pulse

width modulation of transistor Qd. The pulse frequency is 39 kHz. The maximum conducting

time of the pulses is 99% of the pulse cycle time. During the pulse spaces, the motor current

freewheels through diode D8.

At 24 V motor supply voltage, the wire feed rollers' speed is 175 r/min. A wire feed speed of

25 m/min. requires a roller speed of 265 r/min.

Current limit

Resistor R19 produces a voltage drop proportional to the motor current. If the current

exceeds the current limit, IC5 turns off the gate pulses to Qd. When the current falls, Qd

conducts again at the next gate pulse.

The control board has a dynamic current limit controlled by the processor. The current limit is

11 A on starting. When the set speed is achieved, this is reduced to 7 A.

Braking

When the motor starts, capacitor C43 charges up via diode D28: the voltage is limited to

15V by zener diodes D10 and D21. When the motor is to brake, the LED in optocoupler IC8

lights, causing the transistor in IC8 to conduct and discharge capacitor C43 (15 V) to the gate

of transistor Qb. The transistor conducts and short-circuits the motor voltage through

resistors R51 and R64, which limit the current to about 20 A.

13AP01:6 Pulse generator input

DESCRIPTION OF OPERATION

0463 394 001

- 16 -

The pulse generator (encoder), 13G1, is fitted to drive motor 13M1. It generates 60 pulses

per revolution.

At a wire feed speed of 20 m/min, the pulse generator produces a pulse frequency of 5093

Hz.

13AP01:7 Wire selection / Burnback

Wire selection – Solid wire

Short Circuit Termination (SCT) behavior is selected when the trigger is released to adapt to

welding with solid wire.

SCT is a way to stop the welding with some small short circuits to reduce the end crater and

oxidation. It also gives the advantage of a good start performance with solid wire.

Wire selection – Cored wire

A constant burnback time is selected when the trigger is released to adapt to welding with

cored wire.

Burnback

The burn-back time is the time from when motor braking starts until the main contactor in the

power source opens.

13AP01:8 Wire feed speed

The wire feed speed range is from 1.9 to 25 m/min for the YardFeed.

A 5 V reference voltage signal at connection A02 represents a speed of 25 m/min.

The processor monitors the wire feed speed. If the wire speed deviates from the set value by

more than 1.5 m/min for more than five seconds, wire feed will be stopped.

13AP01:9 Gas valve

The gas valve is connected to board contacts G04 and G05. The valve is energised via triac

TC1.

DESCRIPTION OF OPERATION

0463 394 001

- 17 -

13AP01:10 Activation, contactor

The start signal to the power source is connected to board contact G03. The contactor is

energised via triac TC102.

13AP01:11 Gas purge / Inching

Gas purging, flushes gas without voltage or wire feed starting.

Wire inching is used to feed wire without welding voltage being applied.

13AP01:12 Display setting meter / inch

The setting of wire speed units, meter or inch, shown on the digital display is done with the

switch 13S6. When the switch is open, meter is shown. When the switch is closed, inch is

shown.

13AP01:13 Processor, Starting sequence

Processor

The processor stores the feeder program. It monitors the power supply voltages: if the

voltages drop to too low a level, wire feed is stopped, as described in section "13AP01:1

Power supply".

DESCRIPTION OF OPERATION

0463 394 001

- 18 -

Starting sequence

The circuit board displays the starting sequence from power-up.

1. LED1 lights red during 5 seconds. The software is in the boot mode.

2. LED1, LED2 and LED3 lights green. The software has started the application mode.

3. LED1 flashes continously with a green light. The board is initiated, and the wire feed

unit is in the application program.

The software version is indicated by a label on the processor, IC6.

connected to power sources Warrior 500i CC/CV or Warrior 400i CC/CV.

The display unit has two groups of three digits. The left group (DY1–DY3) is used for

displaying set or actual arc voltage and the right group (DY4–DY6) is used to display the

measured welding current.

Data is transmitted to the display board from the power source using a three line serial

interface through the inputs:
