3.3 Electrode sharpeners
Ultima – TIG – cut
NEUTRIX
Use sharpener to sharpen the electrodes, to cut them to
correct length, and to help gather and recycle welding
dust.
Desktop model (recommended) allows more precise
lengths. It recycles dust into liquid instead of air. You can
also use a hand-held model. Only sharpening is possible
with the hand-held model, not accurately cutting to
length.
You can obtain a faster and more uniform grinding result
compared to manual grinding with an optional auto-grind
device.
Tungsten is the most suitable material for welding
electrodes but it is hazardous as waste and when breathed.
3.4 Filling water cooler with coolant
You can fill the water tanks with normal tap water. However,
the degree of water purity as well as the temperature of
the environment determine if you need to apply additives
and/or otherwise take care of the water supply.
When employing TIG system at temperatures below
+8 °C, add an anti-freeze medium.
1. Fill the water tank with 3.5 liters of Kemppi torch
coolant fluid or equivalent (Monopropylenglycol).
2. Use max. 40 % of coolant fluid added to water. This
will provide freezing protection to ‐25 °C.
Do not use distilled or demineralized water. Zinc
deficiency causes corrosion and a risk of leakage.
Even if the temperature stays above +8 °C, use a
small quantity (ca. 10 %) of anti-freeze additive. It prevents
adverse algal growth in warm water.
The amount of cooling fluid required depends on the cable
length of the weld head. Normally, 3.5 litres is sufficient.
Check the level of coolant after several minutes of first
turning on power to top off the coolant level as required.
