Wire cage welding machine used in the production of steel cage, put the tube in the cement machinery mould system for the production of a reinforced concrete pipe, but in actual use may appear may appear unstable failure of welded steel, the following is the analysis of cause of trouble and remedy method.

Fault:

1, steel surface oil and corrosion.

2,. Welding wheel too groove

3 deep groove welding wheel, welding wheel or conductive wheel pressure is too small

4, conductive block or conductive wheel wear.

5 welding of two primary side of the transformer connected copper foil, poor contact steel, the contact surface oxidation or the fastening screw loosening.

6 conductive copper sleeve groove deep, loose slot, dirty.

7, welding voltage is too low. Method: to replace steel or pickling processing; car repair; adjustment; replacement or repair; clean and tighten; replacement tank; adjust the voltage.
