DC ARC WELDING INVERTER
6
NOTE:
This table is suitable for mild steel welding. For other materials, consult
related materials and welding process for reference.
WORKING ENVIRONMENT
CAUTION:
1) Welding should be carried out in dry environment with humidity of
90% or less.
2) The temperature of the working environment should be between -10c
and 40c.
3) Avoid welding in the open air unless sheltered from sunlight and rain.
Keep it dry at all times and do not place it on wet ground or in puddles.
4) Avoid welding in dusty area or environment with corrosive chemical
gas.
5) Gas shielded arc welding should be operated in environment without
strong airflow.
SAFETY TIPS
Over-current/over-voltage/over-heating protection circuit is installed
in this machine. When the network voltage, output current or inner
temperature exceeds the set standard, the machine will stop
automatically. However, excessive use (e.g. too high voltage) of machine
will lead to welder damage. Therefore, please note:
2.1 Ventilation
This welder can create powerful cutting current that has strict cooling
requirements that cannot be met with natural ventilation. Therefore the
internal fan is very important in enabling the machine to work steadily
with effective cooling. The operator should make sure that the louvers be
uncovered and unblocked. The minimum distance between the machine
and nearby objects should be 30cm. Good ventilation is of critical
