There is a large
amount of
residual water
during the tip
replacement.
When the water draining system
operates, the inflow and outflow of water
is not being shut off by the water
inflow/outflow valve which controls the
shutoff / connection of the welding gun
conduit.
Check if there are any
abnormalities with the solenoid
valve controlling the welding gun
conduit and if the solenoid valve is
functioning to shut off the
inflow/outflow of water.
The residual water and welding gun
conduit is not correctly connected.
Check the connection between the
residual water and welding gun
conduit.
The check valve assembly is damaged.
Replace the check valve assembly.
The water tank is damaged.
Replace the water tank.
The solenoid valve assembly is damaged.
Replace the solenoid valve
