Overview

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.

Features

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.

Application

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.

Overview of available Components

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

Series Connection

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

tip B.

Parallel Connection

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.
