What is the cause of no welding current in AC spot welder?
Is there something wrong with your trigger circuit?
The problem is various, should first check whether pressure in place, then check whether the transformer output voltage, and from the point of transformer is good contact welding, welding point and arm fever will generally spot bad contact, and the fixed splint arm is aluminum, the place will be bad.
That machine has a fault, it is recommended that you change a spot, I know there is a very good spot, Shenzhen city Fuweite welding machine Co., Ltd. is the Taiwan total. Product quality is also very good.
