METHOD OF AND APPARATUS FOR BALANCING AN ELECTRODE ARM OF A WELDING DEVICE WITH DETERMINATION OF DIFFERENTIAL BALANCE PRESSURE
摘要
A method for balancing an electrode arm (101) of a welding device (100) is provided. The welding device (100) includes a first electrode arm (101) and a second electrode arm (102) movable with respect to one another and coupled to a reference arm (30). The welding device (100) also includes a compensation actuator (106) coupled to the first electrode arm (101) and to the reference arm (30) to balance a weight of the first electrode arm (101) and including first and second fluid chambers. The method comprises a step of adjusting a differential pressure between the first and second fluid chambers of the compensation actuator (106). The method further comprises a step of determining a differential balance pressure required to balance the weight of the first electrode arm (101) when the first electrode arm (101) moves by more than a threshold amount.
