Hold the handpiece with one hand and support your hand as much as possible. Press the
electrode lightly against the workpiece at an angle of 15–20° to the surface to be coated.
If the electrode touches the opposite edge in this inclined position in the case of small holes or
profi les, you can also hold the electrode parallel to the hole.
Process the surface of the workpiece slowly and evenly until the coating is as fi ne and homoge-
neous as possible. An optimum coating is matt grey and fi ne-pored.
Caution!
Under continuous operation and with a strong energy output, the electrode becomes warmer
than 42°C and its holder heats up. This then leads to a slow heating of the entire handpiece.
• If the handpiece becomes too warm, switch off the handpiece and allow it to cool down.
• For continuous operation, work alternately with two handpieces.
Attention!
If the electrode glows, the coating becomes defective. Sparking also leads to a poor result, as
the melted carbide splatters and cannot be deposited on the workpiece.
• If the clamped electrode starts to glow or sparks fl y, reduce the coating energy.
In the case of very fi ne moulded parts, coating in stages is advantageous because it can some-
