Problem

/ Solutions
6. COOLANT TEMP LED illuminated:
6.1. Coolant is too hot
.
This LED will extinguish when temperature switch TS2
senses that the temperature of coolant in the coolant
reservoir is under 160° F (71° C).
• Check to see if the water coolant is above 160° F (71° C).
• Check to see if TS2 (located in the coolant reservoir) is
open. TS2 is normally closed, and is opened when a
temperature above 160° F (71° C) is reached.
• Using the wiring diagrams, check pins, wires and
connections from TS2 to PCB1.
Repair and/or replace defective component(s), if necessary.
7. COOLANT FLOW LED illuminated:
7.1. Coolant flow is restricted.
This LED will extinguish when flowswitch FS1 senses a
coolant flow of at least 0.5 gpm (1.9 lpm) to the torch. FS1
is a normally open switch that closes when a flow greater
than 0.5 gpm (1.9 lpm) is sensed. See
Coolant Flow Test
Procedure
later in this section to troubleshoot coolant flow
problems.
Note: Coolant flow LED illuminates when the line disconnect
switch is turned ON because coolant reservoir pump M2 is
not activated until the power supply POWER ON (PB1) is
pressed.
