OPERATION
SQUARE WAVE TIG 255
Note that some types of equipment, especially pumps
and motors, have starting currents which are signifi-
cantly higher than their running currents. These higher
starting currents may cause the circuit breaker to
open. If this situation occurs, the user should refrain
from using the Square Wave TIG 255 auxiliary for that
equipment.
___________________________________________
OVERLOAD PROTECTION
This welder has thermostatic protection from
excessive duty cycles, overloads, loss of cooling, and
high ambient temperatures. When the welder is
subjected to an overload or loss of cooling, a
thermostat will open. This condition will be indicated
by the illumination of the yellow Thermostatic
Protection Light on the case front (see Figure A.2).
Also, the Display will be blank, and all of the red
Control Panel lights will be out. The fan will continue
to run to cool the power source. No welding is
possible until the machine is allowed to cool and the
Thermostatic Protection Light goes out.
