FILTER
3.1
General
Sections A to F refer to wiring diagram 3.3
Each unit has its own letter code which is divided into section numbers.
A Filter, Voltage supply
For filtration of the 42 V AC a standard LC--filter in a metal casing is used. The filter
is bolted inside to the rear wall of the tower, close to the cable bushing. The screen of
this cable is connected to the same bolt.
Filters of different makes were used – PE and Corcom – both designed for 1 A/250 V.
In
Out
B Filter, motor wire feeder
From serial no. 0644 a second filter (like “A”) is bolted inside the tower. That’s for
filtration of electrical noise from the wire feeder motor. It‘s the upper filter in the tower.

CONTROL UNIT _ CARRIAGE “D”
4.1
General
The controller consists of 2 circuit boards, the main board MMC231 and the voltage
supply board LPW123. The circuit boards are mounted in separate aluminium frames
which are bolted together.
These are insulated from each other by plastic washers. It is important to prevent
electric current passing through the chassis to the switch regulator for the voltage
supply board, which is bolted to the aluminium frame.
The main board is bolted through 6 spacers and shimmed with 3 mm diameter plastic
washers to give the correct spacing between the switch and the front panel. The 2
central nuts are also insulated using the same type of plastic washers.
LPW123
MMC231
The main board consists of a microprocessor (μP), a drive unit for the display, a
display switch and a drive unit for the motor. The microprocessor is an OTP version
and therefore cannot be reprogrammed. When upgrading to a new software the
complete microprocessor must be replaced.

D1.1 Rectifier, Voltage supply
The inputs are protected by a 1.6 A “fast” fuse. A 10 ohm NTC resistor (R0) limits the
current when the voltage is switched on.
R1 is a varistor that protects the board against a high input voltage. The varistor
short--circuits at voltages above 50 V AC, the current through the fuse rises sharply
and the fuse blows. Occasionally the varistor may short circuit, with the result that the
fuse blows as soon as you connect the supply voltage again. The varistor is easily
replaced by cutting the legs close to the casing, then unsoldering the legs
individually.
The input filter consists of C1, C13, L1 and L2 plus C2 and C12.
The diode bridge, D1 and D7, rectifies the input voltage, which is around 60 VDC at
42 V AC. The voltage from D1 is fed to terminal 13 on terminal block “K1” and to the
motor transistors on the MMC_231 board. D7 supplies the 5 V and 24 V regulators.

The 5 V voltage supply is based on a switch regulator, dimensioned for a max.
current of 1 A .
The base voltage (+ 60 V at 42 V AC) from rectifier D7 and capacitor C3 supplies the
regulator with voltage .
The regulator switch outputs a voltage with a frequency of 100 KHz which is
smoothed by choke coil L3 and capacitor C10.
D6 is a schottky--diode which protects the regulator’s output .
The regulator has a feedback input which monitors the output voltage, via a voltage
divider R12+R13/R11.
Output voltage should be min. 4.9 V and max. 5.1 V .
The regulator is bolted on the aluminium frame and insulated from the frame with
plastic washers.

D3 Motor driver
Drive
The motor is driven by the base voltage from the voltage supply board
(around 60 V DC at 42 V AC supply) and is controlled by 4 MOS--FET
transistors that are connected to an H rectifier bridge.
Speed
The microprocessor generates a modulated pulse width signal. This pulse
width corresponds to the programmed speed, port A4 connection 30. This
pulse--modulated voltage is then smoothed to DC by a RC filter (R17 and
C5), and is fed to a OP amplifier that is wired as a “voltage follower”, i.e. a
circuit that is used to keep the voltage at these two inputs constant. The
second input is a filtered voltage from the motor output. This feedback signal
is split by a voltage divider (R9/R10 across R14) and smoothed by C3. The
zener diode D20 (4.3 V) protects the input against too high a voltage.
The output from the OP amplifier (a pulse width signal that also varies in
frequency) controls the opts witches D16_1 and D17_1. These then pulse the
MOS--FET transistors T6 and T7
Direction
The direction of rotation of the motor is determined by which of the
“diagonals” in the H rectifier bridge is conducting – either T7 and T8 or T6
and T9. Ports A5 (connection 29) and A6 (connection 28) are controlled by
the microprocessor.
Braking
The motor is braked when transistors T6 and T7 short--circuit the motor. This
is also controlled by a pulse width that is varied to ensure smooth braking of
the motor.
Protection
To protect the motor from overload the microprocessor monitors the motor
current. This is read as the voltage drop across shunt R15 (0.47 ohm) and is
filtered by a RC filter (R16 and C4). Zener diode D21 (4.3 V) protects the
input against voltage overload.

The upper control unit (Travel unit) provides the start/stop function for the wire feeder
by means of a relay that is connected between terminals 4 and 5 on the terminal
block.
The relay is mounted in a socket midway along the length of the main board.
Port D2 (connection 22) from the microprocessor goes high (+5 V) and opens T13
via resistor R28. The resistor has been selected to limit the current through T13 so
that the voltage drop across the relay coil is 15 -- 20 V.
The relay output can carry up to 0.5 A. To limit the current on the relay contact, a
500mA PTC (R29) is connected in series with the signal.
The relay is secured to the socket with a piece of foam placed between the top of the
relay and the power unit.

CONTROL UNIT “C”-- WIRE FEEDER
5.1
General
The wire feeder unit is based on the same circuit board as that used for the carriage
control unit. The control units differ only in a few components and the microprocessor
software that runs them.
The circuit board for voltage supply has a 24 V output (terminal 16) that supplies the
gas valve and the start relay.

The base voltage (+ 60 V at 42 V AC) from rectifier D7 and capacitor C3 supplies the
regulator with voltage.
The regulator has a feedback input (pin.1) which monitors the output voltage, via
voltage divider R8/R9. R7 is not mounted. D5 is an over voltage protection for the
reg. output pin.
Output voltage should be min. 22 V and max. 26 V.
The regulator is bolted on the aluminium frame and insulated with plastic washers.

C2 Output gas valve
The lower control unit (wire feeder unit) provides the on/off function for the gas valve
by means of an “open collector” (0 V) output (T12) that is connected to terminals 3 on
the terminal block. The gas valve is a 24 V DC solenoid and the +24 V is connected
to terminal “16” on the supply board.
This output is controlled by the uP and from the frontpanel it’s possible to program
the time for “pre flow” and “post flow” (the time the gas valve opens before welding
start and close after welding stop).
Port D3 (pin 23) from the microprocessor goes high (+5 V) and opens T12 via
resistor R27. The T12 (BC337) is a NPN--transistor 50 V -- 0,8 A.
