8 General Maintenance
Before removing the power
source covers, ENSURE that the
equipment is disconnected from
the mains power supply. When the
equipment is energised LETHAL
VOLTAGES are present on the
electrical components enclosed.
Dust
Care should be taken to prevent excessive
build-up of dust and dirt within the welding
power source. It is recommended that at
regular intervals, according to the prevailing
conditions, the equipment covers be removed
and any accumulated dust be removed by the
use of dry, low pressure compressed air, or a
vacuum cleaner.
Wirefeed
In order to obtain the most satisfactory
welding results from the G.M.A.W. process,
the wirefeed must be smooth and constant.
Most causes of erratic wirefeed can be cured
by basic maintenance. Check the General
Maintenance section of the Wirefeeder
Operators Manual for more details.
Gun Position
For “down hand” fillet welding, the gun is
normally positioned as shown in Figure 6
below with the nozzle end pointing in the
direction of travel.
