The Control Process allows improving the control of the welding variables. Indeed, the DIGIWAVE III is able to alert the user that the value of one of the

following variables is out of a control corridor:

Current welding

Current of the wirefeeder motor (gives an idea of the wire speed)

Arc tension

The control corridor is defined by an upper threshold and a lower threshold that the user can tune for each variable. To tune them, the user can refer to the

minimum and maximum values measured during the previous weld. Those values are accessible in the menu: "Tuning Help".

A fault message is triggered if the time of the outputs on the same upper limit to a control inhibition time T (s)

In the example below, the upper limit is exceeded two times t1 <T and t2> T.

Only t2 exceeded triggers the default

The Control Process page is accessible in the SETUP of the MIG menu. You can choose to activate the control only on certain variables.

To set the threshold values, you can refer to the minimum and maximum values measured during the previous weld. Those values are accessible in the

menu: "Tuning Help".

The control process parameters are associated to one welding program. Those parameters can be different from one program to another.

There are three types of fault detection defined in the menu Configuration > Installation > Fault

Type

Blocking

Immediate blocking as soon as a fault is detected

Fault display at the end of the weld that disappears with

Indicative

acquittal or when a new cycle starts.

No-Blocking

No visible effect, only searchable in fault history

All faults are stored in the history. The following data is available:

Failure

Fault number

Controlled variable

Program number

Date / Time

User identified

Maximum value reached

Total length of the fault

Total length cumulative defects on the variable

When the process control is activated, a colored dot appears next to the controlled variable on the page in MIG welding. If the dot remains green during

welding, no defects were found, otherwise it becomes red.
