the output electrode with any part of your body.

●

Before operation, no concerned people should be left. Do not watch the arc in

unprotected eyes.

●

Ensure good ventilation of the machine to improve duty ratio.

●

Turn off the engine when the operation finished to economize energy sources.

●

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 our authorized maintenance

man.
