7. Operation Notices
7.1 Installation
1. Welding environmental temperature should be between -10
℃
to 40
℃
.
2. Welding should be done in relatively dry environments, with air humidity of not
more than 90%.
3. Avoid areas containing dust or corrosive gas whilst welding.
4. Avoid sunlight or rain, do not let water or rain infiltrate the welding machine.
7.2 Safety
When the Welding machine has encountered over-voltage, over current and over
temperature protection circuit, when the primary voltage, output current and the internal
temperature exceeds the set temperature, the welding machine will automatically stop
working; so you need to note the following:
(1) To ensure good ventilation!
The machine is equipped with internal cooling fan ensure that there is adequate air flow
around the machine.
(2) Do not exceed duty Cycle!
Operators should ensure to use the machine within its normal range of operation,
continually putting the machine in overload will reduce life of the equipment in the longer
term.
(3) Ensure machine is connected to correct voltage!
The machine should only be connected to 15Amp 240v Power supply
