or components inside the machine.
The welding machine generates high temperature and high,heat, which
may cause fire or explosion when used incorrectly,
especially when it is close to combustible materials or explosive gas,
Please do not touch the hot wedge (during welding work or when the
welding machine has not completely cooled down) so as not to burn.
The power supply voltage must match the rated voltage marked on the
welding machine and be reliably grounded. Connect the welding
machine to a socket with a protective ground conductor.
In order to ensure the safety of the operators and the reliable operation
of the equipment, the power supply at the construction site must be
equipped with a regulated power supply and a leakage protector.
The welding machine must be operated under the correct control of
the operator, otherwise it may cause combustion or explosion due to
high temperature.
It is strictly forbidden to use the welding machine in water or muddy
ground, avoid soaking, rain or damp.
