IGBT CO2 - Usage Precautions

Danger
●
Perform maintenance 5 minutes only after the power supply is disconnected, the power indicator
is completely off, and the voltage of the positive and negative bus bars is lower than 36 V; failing
to do so may result in electric shock.
●
Parts can be replaced only by professionals. Do not leave cable stubs or metal objects in the
welder; failing to do so may result in fires.
●
After replacing the control board, set the parameters correctly before using the welder; failing to
do so may result in property damages.
●
Use insulation tapes to wrap the copper noses that connect to cables; failing to do so may result
in electric shock.
Note
!
●
Do not impose force on the control panel and cover plates when moving the welder; failing to do
so may cause the control panel and cover plates to fall off and lead to damages of properties.
●
When moving the welder using a forklift truck, fix the casters of the welder.
●
Install the welder only at the place where the welder can be held stably. Otherwise, falling of the
welder may result in injuries or property damages.
●
Do not install the welder at the place where water spray may occur; failing to do so may result in
property damages.
●
Prevent bolts, washers, or metal rods from dropping into the welder. They may result in fires and
property damages.
●
If the welder is damaged or incomplete, do not install or use it; failing to do so may result in fires
and injuries.
●
Firmly connect the main loop terminal to the copper nose; failing to do so may result in property
damages.
Usage Precautions
Danger
●
To ensure safety, welding must be performed by personnel who understand safe operations and
possess welding skills.
●
Do not use the welder for purposes other than welding.
●
Installation, commissioning, and maintenance of the welder can only be performed by
professional personnel.
●
People using heart pacemakers are not allowed to get close to the welder and welding sites
without doctors' permission.
●
Do not touch the live parts; failing to do so may result in electric shock.
●
Do not use cables with insufficient cross-sectional areas, cables with exposed conductors, and
