MAINTENANCE
ATTENTION: For safety reasons, while servicing the machine, please turn off the power supply and
wait 5 minutes, until the voltage drops to 36V which is a safe voltage.
Maintenance work must be carried out frequently to ensure that the arc welding equipment operates efficiently and
safely.
Give your customers the information they need to understand maintenance methods. This will allow them to carry
out a simple examination of the equipment, to prevent possible failures and to carry out the repair tasks correctly.
Maintenance work prolongs the service life of the welding machine.
