TROUBLESHOOTING
1. Possible function failure of power switch. Compensate it
if necessary.
2. Possible unavailability of input. Compensate it if
necessary.
3. Possible short circuit of input cable, Compensate it if
necessary.
1. Possible misconnection with input of 380V, and
occurrence of over voltage protection status. Reconnect
with input of 220V, and restart.
2. Possible unstable input due to the un-available input
cable or possible connection unavailable spells it's being
of over-voltage protection status.
3. Frequently switching on and off of this welding
equipment in a short period leads this equipments being
of over-voltage protection. Switch off this welding
machine and wait for at least 3 minutes, then restart
this welding equipment.
4. Possible unavailability of the connection of switch and
bottom board. Reconnect it.
5. The 24 V relay of bottom PCB is possibly damaged.
Replace it if necessary.
1. The normal voltage of positive and negative pole of
board VH-07 should be DC 308V.
1.1Possible short circuit occurs, and possible
unavailability of connection of silicon bridge with the
PCB.
1.2 Possible electricity leakage of capacitors, replace
them if necessary.
2. A green light indicator of secondary power supply of top
PCB should be on. Otherwise, it indicates that the
secondary power supply is not functioning. Check the
connection whether is available. If fault cannot be
rectified, please contact the supplier for further advice.
3. Possible unavailability of connection inside this welding
equipment occurs. Check and reconnect if necessary.
4. Possible malfunction of control circuit occurs. Check
otherwise contact the supplier for further advice.
5. Possible damage of the welding torch. Replace it if
necessary.
