Switch.
The Dwell Reed Switch activates the Feed Timer. If this switch is malfunc-
tioning or out of position it will activate the feed at the wrong time. For
instructions on how to check and adjust, refer to the action section on
page 14 for “Possible Problem” Dwell Reed Switch. (Also refer to note
#4 on page 18.)
Sluggish movement
of the Feed.
All Indicators are
functioning cor-
rectly.
All lights flash in
sequence.
(A) Feed Speed
Control.
(A) Readjust the Feed Speed Control located on the air line going to the
Feed Cylinder.
(B) Air Lines. (B) Check the Air Lines for leaks and water. If there is water in the Air
Lines, disconnect and blow out all Air Lines. Remove and clean the Ex-
haust Muffler. Reconnect the Air Lines and the muffler.
(C) Feed
Cylinder.
(C) Turn the power and air off. Check the Feed Cylinder and the Pusher
With Pawl for binding. Move the Pusher With Pawl in and out. The Pusher
With Pawl should move in and out with a slight resistance.
(D) Feed
Solenoid.
(D) If the above procedures check out and the Feed still has sluggish
movement the problem may be the Feed Solenoid. Remove the Air
Line from air inlet of the solenoid and spray a light oil into the solenoid.
Reconnect the Air Line and cycle the machine. If the Feed still has slug-
gish movement replace the Feed Solenoid.

the Upper Weld Tip. Adjust Feed Speed Control so that it places the
pin on the Upper Weld Tip.
(B) Upper Weld
Tip.
(B) Check the Upper Weld Tip for magnetism. Place a weld pin under the
Upper Weld Tip. If the tip does not retain the pin or the magnets feel
weak replace the Upper Weld Tip.
( C ) Pu s h e r
