Installation And Operator Instructions - Lincoln Electric COOLARC-50 Manual De Instrucciones

CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.

Coolant INLET and OUTLET fittings (A) type
21KATS09MPX are placed at the front of the unit. The
blue fitting is marked
equipment); the red ones is marked
coolant from the welding equipment).
The FILL CAP of the coolant reservoir is on front of the
unit (B). Fill Cap can be removed by twisting it off.
The coolant FLOW INDICATOR is accessed by removal
of the reservoir fill cap. Actual return flow is directly
visible by the fill opening (C).
Coolant volume can be monitored through translucent
reservoir in the front (D). The minimum coolant level is
indicated by the line "MINIMUM LIQUID LEVEL" on
label.
Air flow louvers (E): Air flow louvers secure adequate air
circulation. The side louvers allow sucking in cold air
from bottom of the unit. Hot air is removed by the front
louvers.
Voltage switch (F) serve to set voltage according supply
power source 230/400 V.
For convenience you can press and hold the FLOW
SENSOR OFF switch (G) and the torch button to fill the
water system on first usage.
Cables length (H) are adjustable. In order to extend the
cables unscrew the cable glands (I), pull out the cables,
then tighten the cable glands (I).
INCORPORATED INTO
AUTOMATIC FLOW SENSOR TO DETECT LOW OR
NO COOLANT FLOW.
CONDITION WILL CAUSE WELDING OUTPUT TO
AUTOMATICALLY STOP TO PROTECT THE TORCH.
DO NOT SWITCH VOLTAGE DURING POWER
SOUCE IS ON.
Filling The Reservoir
Proper Coolant Addition
Acorox is recommended coolant for COOLARC-50.
For use above freezing: Tap, distilled, deionized, mineral
water. For use below freezing: water and pure ethylene
glycol mixture (10% glycol between at 0°C and 30% at -
15°C).
