Preventive maintenance

Introduction

Deteriorating consumable parts life is one of the first indications that something is wrong with a plasma system.
Reduced parts life increases operating costs in two ways: the operator must use more electrodes and nozzles to cut the
same amount of metal, and the work of cutting must stop more often to change consumables.

Proper maintenance often eliminates the problems that shorten the life of consumable parts. Since labor and overhead
can account for 80% of the cost of cutting, improved productivity can reduce cutting costs dramatically.

Preventive maintenance protocol

The following protocol covers the basic elements of all Hypertherm HySpeed plasma systems.

If inspection suggests that a component is worn and might require replacement, and you would like confirmation of your
decision, please contact Hypertherm's Technical Service department.

The power supply

DANGER

ELECTRIC SHOCK CAN KILL

Turn off all electrical power before removing the power supply cover and set the
line disconnect switch to OFF. In the U.S., use a ìlock-o ut and tag-out” procedure
until the service or maintenance is complete. In other countries, follow appropriate
local or national safety procedures.

1. With power to the power supply turned off, remove all side panels. Use compressed air to blow out any accumulation

of dust and particulates.

2. Inspect wiring harnesses and connections for wear, damage or loose connections. If you see any discoloration that

might indicate overheating, contact Hypertherm Technical Service.

3. Inspect the main contactor for excessive pitting on the contacts, characterized by a blackened, rough surface on any

of the contacts. If this condition exists, replacement is recommended.
