4.5 Operation Notices
▲
Read Section §1 carefully before starting to use this equipment.
▲
Connect the ground wire with the machine directly.
▲
Ensure that the input is single-phase: 50/60Hz, 110V/220V ±10%.
▲
Before operation, none concerned people should not be around the working area and especially
children. Do not watch the arc in unprotected eyes.
▲
Ensure good ventilation of the machine to improve Duty Cycle.
▲
Turn off the engine when the operation finished for energy consumption efficiency.
▲
When power switch shuts off protectively because of failure. Don’t restart it until problem is
resolved. Otherwise, the range of problem will be extended.
▲
In case of problems, contact your local dealer if no authorized maintenance staff is available!
5. Maintenance & Troubleshooting
5.1 Maintenance
In order to guarantee safe and proper operation of welding machines, they must be maintained
regularly. Let customers understand the maintenance procedure of welding machines. Enable
customers to carry on simple examination and inspections. Do your best to reduce the fault rate and
repair times of welding machines to lengthen service life of arc welding machine. Maintenance items
in detail are in the following table.
●
Warning: f or safety while maintaining the machine, please shut off the main input
power and
wa it for 5 minutes, until
capacitors
voltage already drop to safe voltage 36V.
