1.3. Condition to use arc sensing function

1.3. Condition to use arc sensing function​

 

(1)    Must be arc welding with weaving function

 

(2)    If the digital arc welding machine transfers the current and voltage values, arc sensing may be available with the data from the welding machine. Some models of high-end welders provide data for the arc sensing function, in addition to the current, making it possible for arc sensing to be performed by using the data. (Please contact our engineer for more details.)

 

(3)    If it is impossible to execute arc sensing with the data from the welding machine, a device is required to detect the welding current. The device can be installed inside the welding machine or configured as a separate box. With the touch sensing unit, its current and voltage sensors can be used. Otherwise, the system should be configured with the following two types of current detector and similar ones.
