Consider the thickness of the material when you choose the power level.
Try to touch the work piece to be welded as precisely as possible.
With just a little experience you will discover how the angle in which you touch the needle
to the work piece will effect the flow direction of the welding point.
Touching the work piece in an angle of 90° will give you the deepest welding point.
A saw or file burr can serve well as a „welding addition“.
For deeply located welding spots, the electrode should be longer.
It may be helpful to use a graver to broach grains to later weld them on.
It may be helpful to use wire as a welding addition to close holes or as reinforcement.
If ignition problems occur it is helpful to apply light pressure to the needle from the side,
as if you were scratching the surface of the work piece.
6-3 SHARPENING THE ELECTRODES
The electrodes should be sharpened with a diamond grinder with fine or medium grain.
The angle should be ca. 15° (Fig.)
6-4 CARE AND MAINTENENCE
The PUK 3 needs, under ordinary working conditions, only minimum care and
maintenance. Remembering a couple of points is crucial, though, to ensure proper
functioning and a long life for your welding device.
Regularly check the power plug and power cables, as well as welding cables for damage.
Ensure that the hand piece parts are easy to operate.
If necessary, clean the electrode thread of the hand piece to ensure an optimal contact
with the electrode
Warning!
IF FUSES NEED TO BE REPLACED, REPLACE ONLY WITH THE SAME VALUES. IF
DAMAGES OCCUR AFTER INSTALLING INAPPROPRIATE FUSES (I.E. TOO
STRONG) THE WARRANTY BECOMES INVALID.
AUTHORIZED PERSONNEL MAY ONLY OPEN THE DEVICE!
