Machine display in automatic mode

1. Material thickness

2. Visual material thickness and weld shape indicator

3. Operating mode reference

4. Material selection

5. Shielding gas and wire diameter recommendation

6. Wire feed graphic

7. Welding values: Wire feed speed, welding voltage and welding current

MinarcMig Evo 200 automatically sets the machine based on your input selections for plate

thickness in mm, weld shape and material type. The material thickness graphic display shows

the selected plate thickness to be welded. Your machine is automatically set for welding

following these parameters inputs.

As you make your selections you will see the displayed parameters change. For example,

as you adjust the power/plate thickness control, you will see the graphic indicating plate

thickness become thicker or thinner.

The selected operating mode and material type are also shown on the display. The display

also shows a recommendation for shielding gas and ller wire diameter for the material in

question. During welding, the graphical display shows that wire feeding is active including

the wire feed rate. Of all the welding parameters, only ller wire feed speed is visible on the

display all the time. Welding voltage and welding current are only visible on the display during

welding. The last used values remain on the display until welding is restarted or parameter

settings are changed.

When adjusting the arc length, weld shape, or voltage control, the voltage display shows

a comparative scale (-9…0…9) which will disappear from the display after a preset time

following adjustment.

2.8.2 Welding power adjustment in automatic mode

Adjusting the welding power according to sheet thickness aects simultaneously both wire

feed speed and amount of current delivered to the ller wire. This is a good starting point

for welding in dierent operating situations. However, welding joint type and root opening

may inuence the amount of welding power required. Select the correct welding power

using the power control, whilst viewing the graphical display of the llet weld and sheet

thickness indicator. If the llet weld’s sheets are of dierent thickness, use their average as a

default parameter and test weld. The sheet thickness display is given in millimetres and with

steel and stainless steel wires, is based on 0.8 mm ller wire diameter. When using a 0.6 mm

ller wire, set the welding power control slightly higher than the used sheet thickness and

correspondingly slightly lower with 0.9–1.0 mm wires. With aluminium wires, the welding

power adjustment is based on 1.0 mm wire diameter.
