1. General safety procedures

(1) proper personal protection. Welding operation according to the labor protection provisions must wear protective clothing, insulated boots and gloves, and keep dry and clean.

(2) welding work, should first check whether the safe and reliable equipment and tools. Safety checks have not been allowed to start operation.

(3)Welding Electrodes is replaced when you have to wear welding gloves, not bare hands operation. In the charged case, do not move away welding clamp weldment in the armpit or the cable hanging in the neck wound.

(4) in exceptional circumstances (such as body sweating in summer, wet clothes), do not rely on a live table, weldment or contact welding pliers, etc., to prevent accidents. Welding operations in wet locations; on the ground should be covered with rubber sheet or other insulating material.

(5) welder sliding knife, to sideways toward the gates, to prevent the arc spark burns the face.

(6) the following shall be cut off only after the power switch: to change the welding joints; replace the need to divert the second weldment line; mobile workplace; repair welding machine failure and replacement fuse.

(7) welding machine installation, repair and inspection by the electrician, the welder will be allowed to overhaul.

(8) prior to welding, job site should be within 10m of inflammable and explosive materials removed or disposed of properly to prevent fire or explosion.

(9) to leave the job site when work is completed to be cut off the power to clean up the scene to prevent accidents left.

(10) when using the line lighting, the voltage should not exceed 36V.

2. Equipment safety checks

(1) the necessity of equipment safety checks

Welding work, should first check the welding machine and tools are safe and reliable, which is to prevent electric shock and other equipment very important part of the accident.

(2) welding arc welding equipment check before the items.

1) Check the power of the first and second winding insulation and the ground situation. Should check the reliability of insulation, wiring is correct, the nameplate voltage and power match.

2) Check the reliability of power supply ground.

3) Check the noise and vibration.

4) Check the welding current adjustment device reliability.

5) Check whether there is insulation around the damage.

6) Check for short circuit Aluminum Electrode clamp is placed on the pieces to be welders.
