4.4 Troubleshooting of AC/DC315P/250P:

TroubleAnalysisSolution

1. Turn on the machine, no

display of the meter, the fan

doesn’t work, no no-load

voltage output in TIG/ARC

mode.

a. The input voltage is abnormal.

b. The power supply cable isnot in good

connectionwith CP1/CP3 on bottom PCB

PZ-03-B0, or the tie-in is damaged.

c. The power supply switch may be

damaged or unclosed.

d. The connecting cable matching socket

CON1-CON6on power supply

conversion PCB PH-20-A1 is in loose

connection.

a. Check if the input voltage is AC

380V.

b. Check.

c. Check and replace it if necessary.

d. Check.

2. Turn on the machine, the

meter displays, press the

welding torch switch inTIG

mode, there isgas out, no HF,

turn to ARC mode, no no-load

voltage output.

a. The connecting cable matching socket

CON7/CON8 on bottom PCB PZ-03-B0

is in loose connection.

b. The prime relay RELAY1 onbottom PCB

PZ-03-B0 doesn’t close well; the value of

resistor RT1/RT2 increases.

c. The connecting cable matching socket

CON2/CON4/CON5 on bottom PCB

PZ-03-B0 withrectifying bridge is in loose

connection.

d. Some part on control module PK-03-A1 is

damaged.

e. Some part oncontrol PCB PK-05-A4 is

damaged.

a. Check and make sure the voltage

of socket CON1 is DC532V.

b. Check and replace if necessary.

c. Check.

d. Check with a multi-meter if chip

U1 onPK-03-A1 isdamaged.

Check if the 16th pin of U1 is 5V. If

it’s not, replace the chip because

U1 is damaged. Check if diode

D2/D3/D4, audion Q2/Q3/Q4/Q5/

Q6/Q7/Q9, thyristor Q1, zener

diode Z1/Z2/Z3, capacitor C17 or

resistor R32 is damaged.

e. Check if MOSFET U2/U3/U4/U5

or resistor R32 is damaged.

3. Turn on the machine, the

meter displays, but the thermal

resistor RT1/RT2on bottom

PCB PZ-03-B0 heats and

smokes after a while.

a. The connecting cable (+24V) matching

socket CON1 on bottom PCB PZ-03-B0

with socket CON14 on control PCB

PK-05-A4 is in loose connection.

b. The relay RELAY1 on bottom PCB

PZ-03-B0 is damaged.

c. The auxiliary power supply part on

control PCB PK-05-A4 is damaged.

a. Check.

b. Check.

c. Check with a multi-meter if

resistorR35, MOSFET U1, audion

Q2, chip U6 or capacitor C32 on

control PCB PK-05-A4is

damaged.
