Modifying a welding program:
The operation is to be carried out by qualified personnel with optimum knowledge of the
control device programming.
Time taken up to modify a program depends on the entity of the change:
If only one parameter is to be modified, for instance the welding current value, the
operation will take about 45” via the HCM4300 programming unit.
By contrast, if more parameters are to be modified, time can be calculated averagely, by
adding approx. 30” for opening the menu concerned to approximately 10” for each
modified parameter.
Time for modifying 1 parameter : 45"
∼
Time for modifying “n” parameters : 30" + 10 x n
