4.
Interchange the cables.
5.
Re-attach the washers and re-tighten the nuts with a wrench.

Current adjustment with MMA welding mode
•
The welding power is adjusted according to the thickness of the sheet to be welded. The device
is also equipped with an arc length trimmer. The control diode indicated the standby mode of
the device and informs you on a possible overhitting.
•
When you switch the device on, a green standby diode is lit. At the same time, the blinking main
switch light is lit. In case the device is overhitting or the supply voltage too low or too high, the
welding process is automatically interrupted, the yellow overhitting diode is lit. It goes out as
soon as the device is again ready for use. Make sure that there is sufficient space around the
device to allow the air to circulate freely and cool down the device.
Adapting the welding power
•
Adapting the welding power to the thickness of the sheet will also affect the wire feed speed
and current flow to the wire. This allows welding in various operation situations. However, the
type of connection and root opening might influence the amount of welding power needed.
•
Choose the proper parameter via the welding power regulator according to the sheet thickness
of the fillet weld welded. If the sheet thickness of the fillet welds is different, adjust an average
value as standard.
•
The sheet thickness scale is given in millimetres, basing on the wire diameter of 0.8
mm. When
using a 0.6
mm wire, the welding power regulation must be adjusted to a value that is a little
higher than the sheet thickness; when using a 0.9–1
mm wire, adjust a value that is a little lower.
