2. Safety precautions
2.1 Open and check the machine: only qualified personnel should perform to avoid danger or machine
damage
2.2 Turn off input power before open the machine, do not touch the electrical conductors to avoid electric
shock.
2.3 Dirt and dust which may cause short circuit should be kept to a minimum.
2.4 Welding may produce fumes and gases hazardous to health. Use enough ventilation and exhaust at the
arc to keep fumes and gases away from the breathing zone.
2.5 .Arc rays may cause eye injury, please do not watch the arc nor expose to the arc rays.
2.6 Remove fire hazards from welding area, welding sparks and hot materials from welding can easily go
through small crack and cause fire.

* Rated duty cycle 60% means, take 10min as the working cycle, the welding machine work 6min under
the rated current status, rest for 4min. When the welding machine work more than 6min, the temperature in
the machine will higher than the setting value, the overload indicator will on, and machine no output until
the temperature in the machine lower to the setting value. When the overload indicator off, the machine can
work again.
