NOTES AND PREVENTIVE MEASURES
1. Environment
1） The machine should be operated in dry environments.
2） Ambient temperature should be between -10 to 40 degrees centigrade.
3） Avoid welding in high temperature climates. Avoid water damage or water intrusion.
4） Avoid welding in dusty areas or salty water environments where there is a chance of corrosion.
5） Avoid gas welding in environments with strong airflow.
MAINTENANCE
1. Remove dust by dry and clean compressed air regularly to avoid build up on the mother boards.
Use dry compressed air to remove particles that may have deposited during operation in harsh
environments.
2. Pressure of compressed air must be within the reasonable range in order to prevent damaging to
small components of inner-machine. We recommend using a dust can and not an air
compressor.
3. Check internal circuit of welding machine regularly and make sure the circuit connections are
connected correctly and tightly (especially plug-in connector and components). If rust is found,
please clean it, and connect again tightly.
4. Prevent water and steam from entering into the machine. If that happens, please blow it dry and
check insulation of machine. Make sure the machine is dry before operating.
5. If welding machine will not be used for long time, it must be kept with a cover in a dry and clean
environment to avoid corrosion.
