SERVICE INSTRUCTIONS
CAUTION!
STATIC ELECTRICITY can damage circuit boards and
electronic components.
•
Observe precautions for handling
electrostaticsensitive devices.
•
Use proper static-proof bags and boxes.
What is ESD?
A sudden transfer or discharge of static electricity from one object to another. ESD stands
for Electrostatic Discharge.
How does ESD damage occur?
ESD can cause damage to sensitive electrical components, but is not dangerous to people.
ESD damage occurs when an ungrounded person or object with a static charge comes into
contact with a component or assembly that is grounded. A rapid discharge can occur,
causing damage. This damage can take the form of immediate failure, but it is more likely
that system performance will be affected and the component will fail prematurely.
How do we prevent ESD damage?
ESD damage can be prevented by awareness. If static electricity is prevented from building
up on you or on anything at your work station, then there cannot be any static discharges.
Nonconductive materials (e.g. fabrics), or insulators (e.g. plastics) generate and hold static
charge, so you should not bring unnecessary nonconductive items into the work area. It is
obviously difficult to avoid all such items, so various means are used to drain off any static
discharge from persons to prevent the risk of ESD damage. This is done by simple devices:
wrist straps, connected to ground, and conductive shoes.
Work surfaces, carts and containers must be conductive and grounded. Use only antistatic
packaging materials. Overall, handling of ESD-sensitive devices should be minimized to
prevent damage.
Service aid
We can offer a number of service tools that will simplify the service.
Soft-starting tool SST 3
The soft-starting tool SST 3 is made for ESAB's single phase inverters and for 3-phase
inverters with 250 A output current. Ordering no. 0459 534 881.
The SST 3 is replacing the SST 1, which only can be used for the single phase inverters.
The tool includes:
Soft starting rectifier, cable set, voltage test board, gate pulse load and shunt voltage resistor
for single phase inverters with analogue control board (Arc 151i A31, Arc 152i A31 and
OrigoArc).
For the 3-phase machines there are: soft-starting-voltage adapter with current limit and
temperature-switch jumper.
