What is the reason that the welding band saw blade is not firmly used after two years of flash butt welding machine? How to solve?
It is suggested that the new jaw be replaced and the two maintenance of transformer shall be carried out. Our company will do the maintenance and maintenance of old machines for the major steel wire rope and steel cord industry all year round
Check the electrode face of the welder. There is something wrong with it.
In general, this is caused by the contact corrosion of the AC contactor. You have changed the new one, you can rule out this reason. But I suggest you check the contact point of this AC contactor. If the check is OK, you should measure your voltage. Is it high enough?. Is there any change in your power off switch?. Is the clearance between your two electrode plates reasonable?.
