Water Draining System – CWDS-01 -
- 8 -
8. Operating principle
Start the water draining system before replacing the tip to prevent a large amount
of water running out from the welding gun when the tip of the gun is removed. In the
water draining system, the solenoid valve controls the cylinder movement, which drives
the water tank to suck up water continuously. The residual water that is taken into the
water tank is drained to the condensate by the check valve so that the welding gun and
the piping are constantly maintained at a negative pressure at the same time.
9. Workflow
(1) The robot starts the tip exchange program.
(2) At the same time, shut off the water inflow/outflow check valve which controls the
shutoff / connection of the welding gun conduit.
(3) Start the water draining system and remove the water pressure in the welding gun
to maintain a constant negative pressure.
(4) Remove the tip.
(5) The robot executes the tip replacement program.
(6) Once the tip replacement is complete, turn off the water draining system and open
the valve.
(7) After the replacement is complete, make sure that the robot runs the water and that
any air in the water pipe is removed before welding.
