3-4. RECONNECTION FOR MOMENTARY TRIG-

GER OPERATION

The CS-3A is factory wired to complete each timed weld

only if the gun switch is held closed throughout the spot

weld cycle. If the gun switch is released before the

SPOT TIME control times out, the spot weld will not be

completed.

The CS-3A can be wired to complete each timed weld

after a momentary closure of the gun switch. In this

case, the spot weld cycle ends only after the SPOT

TIME control times out. To wire CS-3A for momentary

trigger operation, proceed as follows:

WARNING: Read and follow safety informa-

tion at beginning of entire Section 3 before

proceeding.

1. Remove wrapper.

2. Locate unconnected end of lead 44 originating at

terminal B on terminal strip 1T.

3. With SPOT-CONTINUOUS switch S51 in the

CONTINUOUS position, connect friction connec-

tor on lead 44 to the normally-open terminal (the

only unused terminal) on S51.

4. Reinstall wrapper.

OM-1086 Page 6

SECTION 4 − OPERATOR CONTROLS

4-1. SPOT-CONTINUOUS SWITCH (Figure 3-1)

The SPOT-CONTINUOUS switch provides selection of

either a continuous weld or a timed weld operation.

Placing the SPOT-CONTINUOUS switch in the SPOT

position provides weld current for the time period set by

TIME RANGE switch and SPOT TIME control. The

SPOT TIME control begins to time out when the gun trig-

ger is closed.

Placing the SPOT-CONTINUOUS switch in the CON-

TINUOUS position provides weld current for as long as

the gun trigger is closed.

4-2. TIME RANGE SWITCH (Figure 3-1)

The TIME RANGE switch provides selection of the spot

weld time range. Placing the TIME RANGE switch in the

.2 to 2.5 SEC position provides .2 to 2.5 seconds of weld

time. Placing the TIME RANGE switch in the 2.5 to 5

SEC position provides 2.5 to 5 seconds of weld time.

4-3. SPOT TIME CONTROL (Figure 3-1)

The SPOT TIME control provides selection of spot weld

time within the time range selected. The scale surround-

ing the SPOT TIME control is calibrated in seconds and

provides a direct reading of spot time when the TIME

RANGE switch is in the .2 to 2.5 SEC position. Double

the scale to read spot time when the TIMER RANGE

switch is in the 2.5 to 5 SEC position.

Rotating SPOT TIME control clockwise increases spot

weld time.

4-4. BURNBACK TIME CONTROL (Figure 3-1)

The BURNBACK TIME control provides selection of the

time that weld current is present on the electrode wire

after wire has stopped feeding. By keeping weld current

present on the electrode wire, the wire burns away from

the workpiece and toward the contact tip.

If electrode wire sticks to workpiece, the BURNBACK

TIME control setting should be increased.

If electrode wire burns back into contact tip, the BURN-

BACK TIME control setting should be decreased.

The scale surrounding the BURNBACK TIME control is

calibrated in seconds. Burnback time ranges from 0

through .25 seconds.
