CUTTING SERIES EQUIPMENT
Troubleshooting
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

◆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!
