SECTION 4 MAINTENANCE
4.1 GENERAL
If this equipment does not operate properly, stop work immediately and
investigate the cause of the malfunction. Maintenance work must be
performed by an experienced person, and electrical work by a trained
electrician. Do not permit untrained persons to inspect, clean, or repair
this equipment. Use only recommended replacement parts.
Be sure that the wall disconnect switch or wall circuit breaker is
open before attempting any inspection or work inside of the
Powercut-1500.
4.2 INSPECTION AND CLEANING
Frequent inspection and cleaning of the Powercut-1500 is recom-
mended for safety and proper operation. Some suggestions for inspect-
ing and cleaning are as follows:
A. Check work cable for secured connection to workpiece.
B. Check safety earth ground at workpiece and at power source chassis.
C. Check heat shield on torch. It should be replaced if damaged.
D. Check the torch electrode and cutting nozzle for wear on a daily basis.
Remove spatter or replace if necessary.
E. Make sure cable and hoses are not damaged or kinked.
F. Make sure all plugs, fittings, and ground connections are tight.
G. With all input power disconnected, and wearing proper eye and face
protection, blow out the inside of the Powercut-1500 using low-
pressure dry compressed air.
Water or oil occasionally accumulates in compressed air lines. Be
sure to direct the first blast of air away from the equipment to avoid
damage to the Powercut-1500.
H. Occasionally, bleed all water from the filter beneath the air filter-
regulator.
4.3 PT-32EH TORCH CONSUMABLE PARTS
Make sure power switch on POWERCUT-1500 is in OFF position
before working on the torch.
The PT-32EH torch head contains a gas flow check valve that acts in
conjunction with the flow switch and circuitry within the power source.
This system prevents the torch from being energized with high voltage
if the torch switch is accidentally closed when the shield is removed.
Always replace torch with the proper torch manufactured by ESAB
since it alone contains ESAB¹s patented safety interlock.
To assemble the consumable parts, refer to Figure 3.3 .
