CLOSED-COUPLED HOLDERS

ADJUSTABLE WATER TUBE USE

For use where welding space is limited. Standard body length is 3 inches. Other lengths are made on request; minimum

length 2 inches.

It is very important that resistance welding electrodes be kept as cool as possible; excessive heat softens them, allowing

the nose to mushroom and weld quality to drop.

Adjustable water tubes are used to deflect incoming coolant water to the full extent of the water hole in the electrode.

Before installing a tip, check that there is an adjustable water tube in place and that it is pulled out far enough so that it

will contact the end of the water hole in the tip.

The drawing shows a typical straight holder, but the principle is the same for all types of holders.

Adjustable water tube correctly positioned in tip. Cold water will strike the hottest part of the tip first.
