The air gap between the electrodes varies from 1mm to 2.5mm according to different materials, but the gap between the electrodes must be constant. We recommend setting the pitch to 1.5mm. However, if the material is quite thick or the part to be spliced or thick at the tail is thicker, the spacing can be increased appropriately.
The minimum pitch is 1mm. If the distance between the store and the ground roller is small, pay attention to cooling the electrode and ensure that its temperature does not exceed the safe operating temperature.
Please refer to the machine manual for the procedure of correcting the gap. If you need an instrument to measure the electrode gap, please contact us and we will provide you with a meter for free.
