Trimming the arc length
•
The arc length regulator shortens or lengthens the arc, thus influencing the welding temperature.
A shorter arc is less hot, a longer one is hotter. The arc length trimmer influences also the
welding properties of the arc and the spatters with the different combinations of diamters of the
welding wire and shielding gases.
•
In case the weld is too convex, the arc is too short or too cold. In that case, lengthen or heat the
arc by turning the regulator clockwise. In case you wish to weld with a cooler arc, e.g., to avoid
that a hole is burnt to the base material, shorten the arc by turning the regulator anticlockwise.
You can adapt the welding power if necessary.
•
After trimming the arc, it does normally not need to be re-adjusted in case the thickness of the
sheets welded changes.
Maintaining and cleaning
When maintaining the device, consider the utilisation ration and environmental conditions. If used
properly and maintained regularly, the device will spare you unnecessary dysfunctions.
Warning!
Unplug the device before working on electric cables.
Daily maintenance
•
Remove weld spatters from the contact tip of the welding gun and check the individual parts.
Immediately replace damaged components.
•
Check if the insulating tips of the welding gun neck are not damaged and are properly fixed.
Isolating parts damaged require immediate replacing.
•
Check the tightness of cable connections of the welding gun and earthing cable.
•
Check the condition of supply voltage and welding cable, replace defect cables.
Maintaining the wire feed mechanism
The wire feed mechanism should be maintained at least when replacing the coil.
•
Check the wear and tear of the notch of the wire feed roller and replace the roller if necessary.
•
Clean the wire feed of the welding gun with the help of compressed air.
