2.6 Operation Notices

▲

Read

this manual

carefully before starting to use this equipment.

▲ Conne

ct the ground wire with the machine directly.

▲

Ensure that the input is three-phase: 50/60Hz, 380V ±10%.

▲ Bef

ore 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!
