C. Ensure that you wear the safety equipment and dress for the protection

of your eyes and skin;

D. Ensure that there is proper ventilation on place of welding to prevent

injury or hurt by smoke and gas exhaustion;

E. Do not open the DOS shell of the welder or use it in open position.

2.2 Prevention from burn and fire

A. Always keep the welder with a distance 30cm away from the wall and

50cm away from any combustible articles;

B. Keep sparks away from tinder or the open holes;

C. Fasten the welder properly with fixed bolts if it is to be installed on high

position for use;

D. Do not weld tubes, hermetic tubes or vessels through which combustion

gas is traveling.

2.3 Usage

A. Always disconnect the welder if the welder is not in use;

B. Do not touch any electrical components in the welder;

C. Do not wear wet or torn gloves when using the welder;

D. Always select correct cables for use with the welder and always ensure

that correct cables are property connected to the welder;

E. Replace all worn cables or wrap the worn cables with insulation tape

for temporary use;

F. Do not place heavy object or any glass of water on the welder. If you
