Free warranty repairs relate only to manu-
facturing defects on the product (hidden
and external) and do not relate to the wear
of the product as a result of excessive load
or normal use or damage of the product
caused by incorrect use.
y
In the event of a dispute between the buyer and the
vendor in respect to the purchase contract that was not
resolved directly between the parties, the buyer has
the right to the trade inspection authority for an out-
-of-court settlement of the a consumer dispute. At the
website of the trade inspection authority there is a link
to the tab „ADR-amicable dispute resolution“.
Waste disposal
PACKAGING MATERIALS
y
Throw packaging materials into a container for the
respective sorted waste.
ELECTRICAL EQUIPMENT AND
CONDUCTORS / TIG TORCH
y
Do not dispose of unserviceable commodities in house-
hold waste, but dispose of them in an environmentally
safe manner. According to Directive
2012/19 EU, electrical appliances must
not be thrown out with household
waste, but rather handed over for eco-
logical disposal at an electrical equip-
ment disposal point. You can find infor-
mation about collection points and
collection conditions at your local town council office.

GRINDING THE ELECTRODE
y
If the electrode is not sharp as per fig.6A, then it is nece-
ssary to grind it into a point along its longitudinal axis
with a regular cone so that the tip is centred, which is
necessary to ensure that the welding arc does not devia-
te. Fine grinding with a perfect cone has a fundamental
effect on the lifetime of the electrode, quality and the
welding process. A cone with a rough surface burns
away faster. An incorrectly ground electrode needs to be
ground more frequently.
Fig. 6B
Fig. 6A
The optimal grinding result with an even cone can be
achieved by fastening the electrode into a cordless drill (at
an appropriate low speed) and while the electrode is rota-
ting, place it on a sanding belt of a belt grinder, on which
a grinding line is marked and from which the electrode
should not deviate during grinding. During the grinding
process, it is necessary to maintain the angle of the cordless
drill relative to the level of the grinder as required because
the angle of the cone has an effect on the necessary
welding current. It generally applies that the greater the
angle between the sides of the cone (fig.8), the greater the
welding current that needs to be set than would otherwise
be required for a cone with a lower pitch, see table 4.
Fig. 7
The electrode will need to be reground regularly depen-
ding on the wear of the electrode or in the case of undesi-
rable contamination occurring.
