Parker Automotive manufacturing focus includes body and assembly, power train, metal stamping, components and trim.
Water Retract Actuator is a solution designed to prevent excessive water spillage during
the routine tip change of a spot welding gun. Excessive water spillage within a weld cell
environment presents a number of hazards including, electrical shock, slip hazard,
equipment damage, and damage to the product that is being manufactured. The Water
Retract Actuator reduces the water pressure in the closed-off cooling circuit which
eliminates the problems of water being expelled under pressure during a tip change.
Parker’s water retract solutions are available either as individual components that can be
assembled by either the OEM or end-user, as a retooling kit allowing existing systems to
be modified, or as a frame mounted solution designed for floor or robot mounting. Parker’s
proven cylinder and actuation technology delivers trouble free operation, while materials
used ensure compatibility with all cooling water fluids leading to a long service life.
Parker Hannifin has developed an extensive range of products to accommodate water
cooling of spot welding equipment in car manufacturing plants worldwide. This product is
the best solution to prevent excessive water spillage during the tip change process of a
spot weld gun. The Water Retract Actuator solves a number of problems for the ‘body-in-
white’ department. It reduces the water pressure in the closed-off cooling circuit
eliminating the problems of spilt cooling water on unpainted car body parts, expensive
equipment and the production floor. The Parker Hannifin Water Retract Actuator has been
developed according to automobile manufacturer’s specification and can be supplied for
both new and retooling programs. All our products are designed specifically to work with
existing water cooling systems.
For simplified installation and optimum performance of the existing cooling
water system, Parker can develop a customized water retract solution that
consists of the following main components
- Water retract actuator
- Control valve to operate water retract actuator
- Mounting plate
- Water connection tube / fitting kit
Scenario 1 , the WRA can be placed on the IN line of the water manifold. In this situation,
you would engage the unit and remove tip B first, replace it, and then remove tip A.
Scenario 2 , the WRA can be placed on the OUT Line of the water manifold. In this
situation, you would engage the unit and remove tip A first, replace it, and then remove
In parallel configuration, the WRA is placed on the IN or the OUT line of the water
manifold. In this situation, you would engage the unit and then you would be able to
remove both tips at the same time.
