2.12 Operation Notices
Read safty instruction and Chapter 1 carefully before attempting to use this
◆
equipment.
Connect the ground wire the machine directly
◆
In case closing the power switch, no-load voltage may be exported.Do not touch
◆
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 source.
◆
When power switch shuts off protectively because of failure.Don't restart it until
◆
until problem is resolved.
Otherwise,the range of problem will be extended.
3.1 Troubleshooting
◆Before arc welding machines are dispatched from the factory, they have already been
debugged accurately. So forbid anyone who is not authorized by us to do any change to
the equipment!
◆Maintenance course must be operated carefully. If any wire becomes flexible or is
misplaced, it maybe potential danger to user!
◆Only professional maintenance personal who is authorized by us could overhaul the
machine!
◆Guarantee to shut off the arc welding machine's power before turn on the outline of
the equipment!
◆If there is any problem and has no the authorized professional maintenance personal,
please contact local agent or the branch company!
