POWER SWITCH (Figure 6-1)

POWER

Placing the POWER switch in the ON position energizes

the Carriage Control circuitry. When the Carriage Con-

trol is energized, the Travel Meter display comes on.

Placing the POWER switch in the OFF position deener-

gizes the control.

JOG DIRECTION SWITCH (Figure 6-1)

The JOG DIRECTION switch is a spring-loaded,

double-pole double-throw (DPDT), center-off switch

which allows the operator to jog the carriage in the se-

lected direction at the speed selected on the JOG

SPEED control (see Section 6-3). Holding the switch in

the left or right position energizes the Carriage Control

motor; releasing the switch stops the carriage. The JOG

DIRECTION switch is not functional when the TRAVEL

DIRECTION switch is actuated.

IMPORTANT: If jogging the unit and the START button

is pressed, the unit will weld in the direction selected by

the JOG DIRECTION switch. The unit will weld at the

speed selected by the TRAVEL SPEED control (see

Section 6-5). When the JOG DIRECTION switch is re-

leased, the unit will weld in the direction selected by the

TRAVEL DIRECTION switch. The unit stops welding

when the STOP button is pressed.

JOG SPEED CONTROL (Figure 6-1)

The JOG SPEED control is a one-turn potentiometer

which provides a means of selecting the rate at which

the carriage will jog in either direction on the beam.

Rotating the control clockwise increases the jog speed,

while rotating the control counterclockwise decreases

jog speed. The scale surrounding the JOG SPEED con-

trol is based on a percentage of the maximum travel

speed of the unit (125 ipm or 3.2 mpm); it does not repre-

sent an actual inches per minute or meters per minute

value.

The actual jog speed is displayed on the digital meter

while the Carriage Control is in the jog mode of

operation.

IMPORTANT: This control may be adjusted while the

carriage is moving.

TRAVEL DIRECTION SWITCH (Figure 6-1)

The TRAVEL DIRECTION switch is a double-pole

double-throw (DPDT), center-off switch that allows the

operator to move the carriage either to the right or left on

the beam. To use the TRAVEL DIRECTION SWITCH,

place the switch in the position corresponding to the di-

rection (right or left) that the carriage must travel, and

press the START button. The carriage will travel at the

speed selected on the TRAVEL SPEED control (see

Section 6-5). When the TRAVEL DIRECTION switch is

in the center position, the unit welds, but the carriage

does not move.
