Water Cooling Attachment

When using currents over 600 amperes at high duty cycles water cooling always increases contact tip life. The cooling attachment, Part No. T12928 must be ordered seperately. Installation instructions are includ- ed in the kit. Connect the attachment to the water sup- ply and the drain with rubber tubing obtained locally. Water flow should be between 1/2 to 1 gallon (1.9 to 3.8L) of tap water per minute.

K149 Installation (See Figure C.5)

1. Install the K149 attachment before mounting the

K148 nozzle on the welder.

2. Place a small C-clamp on the spring supporting members (A) and (B) in such a manner that the spring can be compressed. Look up into the hole in the end of contact tip and tighten the C-clamp until the tang lifts off the surface of the tip.

3. Remove the 3/8” (9.5 mm) set screw (C) in the body (A).

4. Remove the contact tip clamping nut (D) and the contact tip.

5. Remove the brass thread protecting collar (E).

6. Remove the dirt shield (F) from the barrel of the nozzle.
