6. OPERATION OF CONTROL PANELS
6.1 General operation steps for the control panel on the power supply part(recommended)
After the machine is powered on, the system will be under the functional state when the machine is
shut down last time. If users want to continue the original welding task, do not operate the control
panel but just carry out welding directly. However, if users want to change the welding task or welding
instruction, they should operate the control panel firstly. The recommended operation steps for the
control panel on the power supply part are as below.
1) Select the welding mode
Select the desired welding mode by pressing the selecting key in the welding mode selecting zone (Figure
5.2) if necessary.
2) Select the base metal type
Select the desired base metal type by pressing the selecting key in the base metal selecting zone (Figure
5.3) if necessary.
3) Select the gas type
Select the desired gas type by pressing the selecting key in the gas selecting zone (Figure 5.4) if
necessary.
4) Select the welding wire type
Select the desired welding wire type by pressing the selecting key in the wire selecting zone (Figure
5.5) if necessary.
5) Select the operation mode
Select the desired operation mode by pressing the selecting key in the operation mode selecting zone
(Figure 5.9) if necessary.
6) Select the parameter to be viewed or modified
If necessary, select the segment, to which the parameter to be viewed belongs, by pressing the selecting
key in the welding process parameters selecting zone (Figure 5.6), and then select this parameter by
pressing the selecting key in the current column parameters selecting zone (Figure 5.7) or voltage
column parameters selecting zone (Figure 5.8), and the current value of this parameter will be displayed
on the current column or voltage column parameters display meter. Users can modify this parameter by
adjusting the control knob (Figure 5.10) when the corresponding parameter LED blinks
6.2 Parameters in MMA
There are 5 adjustable parameters in MMA welding, namely arc ignition current, arc ignition time, arc
current, arc characteristic (arc force) and arc breaking voltage. These parameters can be operated
only through the control panel on the power supply part. Besides, Select the desired welding mode before
any operation on parameters.
