Pull the welding gun trigger. The filler wire will move forward, and a short circuit will occur and
the arc will be established. Keeping the gun trigger depressed, the molten weld pool will start
to form. Begin to travel the gun forwards, in a controlled manner and travel speed. Providing
you have correctly set your equipment, the quality of your weld deposit is now determined by
your skill and technique.
The resulting weld deposit, width and shape, should be consistent in appearance and quality.
If you are welding too fast the weld bead may be too thin or even intermittent in appearance.
Try to slow your travel speed slightly and maintain an even approach to the joint. If you are
welding too slowly, you may find the weld deposit is too heavy, the weld piece overheats and
possibly burns a hole through the plate. All that may be required to ensure a successful result
here is an increase in forward travel speed, but you may also need to reduce the power setting
slightly, to achieve the desired result.
As with all craft skills – practice will make perfect! For more information, visit the Welding ABC
section in www.kemppi.com.
6.1 HOT SPOT function
NOTE!
The HOT SPOT component kit is suitable for use with the FE 20/25 welding guns only.
Setting and function
1.
Before using HOT SPOT function, release the pressure tension arms at the wire feed
mechanism.
2.
Rotate the filler wire spool slowly clockwise, removing the filler wire away from the FE
welding gun contact tip and neck.
3.
Fit the special HOT SPOT electrode adaptor and carbon electrode into the gun head as
shown.

4.
Select HOT SPOT mode with the control panel button 6.
5.
Select the required HOT SPOT power level. There are 4 power level options depending
on the machine type in use.
6.
Place the carbon electrode to the work piece, fixing, or area requiring spot heating.
7.
Pull the trigger to activate the HOT SPOT function. The electrode will quickly heat up and
depending on the power level set , will glow red hot.
8.
When sufficient heating effect is reached, release the trigger and remove the electrode
from the work piece.
9.
When HOT SPOT process is complete, press control panel button 6 to return the machine
to standard MIG/MAG mode.
10. When cool and safe to handle, remove the HOT SPOT carbon and holder, replacing the
standard FE welding gun parts ready to continue welding.
NOTE!
HOT SPOT function is only possible in 2T gun trigger mode. If 4T selection is made, the
function will automatically revert to 2T operation.
