Operational procedures for welder

    The tower crane,The welder, also is known as current welding machine, construction hoists  mainly works through the instantaneous high-voltage high-current large amount of heat generated by contact with each other so that the two contact surfaces of metal parts instantly meltedfused,  The tower crane,so that two metal welded together.

(i) Before welding,we should in accordance with the reinforced section, adjust the secondary voltage, not to be welded in excess of the provisions of the diameter of steel welder. The tower crane

(ii) Circuit breaker contact points,and the electrode should be regularly Mitsuma, the second circuit all the connections, fastening screws should be on a regular basis, cooling water temperature should not exceed 40 ℃,  The tower crane,displacement Should be based on temperature regulation.

(iii) when Weld steel bars longer, we should set the brackets, with the transport operators of steel in the weld should be taken to avoid spark injury.

(iv)flash zone should be located baffles, weldinsg related personnel shall not enter.
(v)When Construction in winter, the temperature of not less than 8 ℃, when operational, should be placed to make the machine cooling water. The tower crane

(vi)After operation, we should cut off the power supply,lock gates boxes.
