NOTICES OR PREVENTIVE MEASURES
1、Environment
1） The machine can perform in environments where conditions are dry to a humidity level of max 60%.
2） Ambient temperature of -10 to 40 degrees centigrade.
3） Avoid welding in direct sunshine, in rain or wet areas.
4） Do not use the machine where the air is polluted with conductive dust or corrosive or flammable gasses.
5） Avoid gas welding in strong winds.
2、Safety
The welding machine has a protection circuit for over voltage, over current and overheating. When
voltage, output current and temperature of the machine has exceeded its limits the welding machine will
stop working automatically to protect the machine, users must pay attention to the following.
1） The working area is adequately ventilated！
Our welding machine is a powerful machine, when being operated it generates high currents, and natural
wind will not meet the machines cooling demands. So there is a fan inside to cool down the machine.
Make sure the air intake is not blocked or covered that there is a 0.3 meter space from welding machine
to objects around the machine. User should make sure the working area is adequately ventilated. It is
important for the performance and the longevity of the machine.
2）Do not over load！
The operator should understand the duty cycle of the machine.
Duty cycle is out of 10 minutes i.e.:
60% @ 200A means 6 minutes welding 4 min cooling
100% @ 155A means 10min welding 1min cooling etc…
Make sure welding current doesn’t exceed max duty cycle current.
Over-load current will damage and burn up machine.
3）Over or under voltage！
Power voltage can be found in diagram of main technical data. Automatic voltage compensation circuit
will assure that welding current is kept in correct parameters. If power input voltage exceeds or drops
below suggested voltage input parameters it will damage components of the machine. The operator
should understand the situation and take preventive measures.
WARNING!
Before connecting welding cables make sure the power is off.
The correct way is to connect the welding cables to the machine first, and make sure they are
firmly tightened and then connect the power plug to the power source.
WARNING!
During welding, DO NOT pullout or insert any plugs or cables, It can lead to life-threatening
danger and cause damage to the machine.
