1.1 CONTROL PANEL
1. Connect the power cord to the power socket located on the rear panel, turn on the power switch (SW1),
then push the PB1 button, the PB1’s LED should light up indicating power supply is ok.
﹡
Please make sure the E-Stop button is not pressed/activated before usage. All controls become
invalid when E-Stop button is pressed.
2. S2 ( WELD / TEST ) Switch enable / disable welding source activation output.
3. S3 ( AUTO / MANU ) Switch select the operation mode.
Manual ( MANU )：Turn table rotation is controlled by the foot switch
Automatic ( AUTO)：The start of the rotation is activated by the foot switch, the duration of the rotation and
is controlled by the ( TIMER ) knob on the front panel from for a duration of (0~60
second).
4. S4 ( ←/ →) Direction switch select the direction of rotation (clockwise or counterclockwise.)
5. S5 ( WELD / RAPID ) Switch select the operating
Welding speed ( WELD )：Turn table rotation speed can be adjusted from（WELD SPEED）knob on the
front panel.
Full speed (RAPID)：Turn table rotation speed is set at full speed.
﹡
Press E-Stop button in case of any emergency situation. All motion and procedure would stop
immediately. Reset the E-Stop button and push PB1 again after clearing the emergency
situation to return the system to operation mode.

2.1 TROUBLE SHOOTING GUIDE
SYMPTOMS
POSSIBLE CAUSES／REMEDIES
Power indicator light does
not illuminate. A. Wrong selection of input power：
Select the correct input power (110V or 220V)
B. Blown fuse：
Check the circuitry and find out the blown. and then, replace fuse.
C. Input power switch malfunction：
Check and replace the power switch.
D. Transformer has no output voltage：
(1) Check if the input voltage, it should be AC110V/ 220V.
(2) Measure CN8 for Pin 1 & 3, there should be 24VAC, and pin 2 & 3
should be 18VAC, if one of the voltage is not correct,
please replace a
new transformer.
E. The flat cable is damaged：
(1) Check relay board CN1 Pin 7 & 8, it should read 24VDC.
(2) Measure Front panel CN1 Pin 7 & 8, it should read 24VDC, if not,
replace the flat cable.
F. PB1 is damaged：
Keep PB1 pressed and measure front panel PB1’s connection (CN1’
s Pin
7 & 8). If no connection, replace a new PB1..
Motor has no motion. A. Motor coil is damaged：
Use ohm meter to measure CM1 female plug pin 1&2 and It should give
you 2 ohm. If 2 ohm doesn't exist, replace the motor.
B. Motor has power input, but no motion：
Measure CM1 male socket Pin 1 & 2 - if there is 6.5VDC, then replace a
new motor.
C. I/O board is damaged
：
(1) Check Relay board CN9 Pin 11&12, the reading should be about
6.5VDC voltage.
(2) Measure CM1 male socket Pin 1 & 2 - if there is no 6.5
VDC, replace a
new I/O board.
Welding action not
responsive. A. Weld/Test switch is damaged：
Switch to "Test" position and check if relay board D10 illuminates, if not,
please replace the front panel board.
B. Relay board is damaged.
Switch to "Test" position and check if relay board D10 illuminates, if yes
but has no action, please replace the relay board.

2.1 TROUBLE SHOOTING GUIDE
SYMPTOMS
POSSIBLE CAUSES／REMEDIES
Forward / Reverse
revolutions not functioning
correctly.
A. Footswitch is damaged：
(1) Measure footswitch connector Pin 1&2, step on the footswitch and
measure Pin 1&2 is shorted. if not, replace a new footswitch.
(2) Step on the footswitch and check if relay board D11 illuminates, if
yes ,but has no action, replace a new relay board.
B. Forward / Reverse revolution switch is damaged：
(1) Switch to "Forward" position and check if Relay board D3
illuminates, if not, please replace the front panel board.
(2) Switch to "Reverse" position and check if Relay board D4
illuminates, if not, please replace the front panel board.
C. K1 ~ K4 relay is damaged：
(1) Switch to "Forward" position and if Relay board
D3 illuminates but the
relay has no action, please replace the relay board.
(2) Switch to "Reverse" position and if Relay board
D4 illuminates, but the
relay has no action please replace the relay board.
Can not adjust speed. A. Motor control PCB is damaged：
(1) Check the motor control PCB. It should have an input voltage of
30VDC between DC+ & DC-.
(2) Adjustment weld speed, measure A1 & A2, it should read approx.
6.5VDC, if not, voltage replace the motor control PCB.
B. Weld / Speed switch is damaged (Weld /Full speed)：
(1) Switch to Manual mode and adjust the weld speed dial to about 50%
of the full speed, then step on the footswitch.
(2) Switch to both weld and speed positions, the motor should respond
with slow and fast speeds respectively, if not then replace a new front
panel board.
C. The potentiometer is damaged：
(1) Detach the Front panel board CN2 connector, use ohmmeter to
measure Pin 1 & 2.
(2) Rotate the weld speed variable resistor's and check if the resistance
value is changing. If not, please replace VR1.
Weld timer not functioning A. T1 Timer is damaged：
(1) Switch to "Auto" position and step on the footswitch.
(2) CheckT1 the motion window of the timer, the "UP" signal should lit, if
not, please replace relay board.
B. T1 The Timer is unable to stop
：
(1) Detach the Relay board J1 connector, measure Pin 1&2.
(2) T Rotate the timer knob and see if the resistance between Pin 1&2 is
changing from 0~1M ohm. If not, please replace the VR2 (Timer
knob).
