Mais marco ma envoyer un roman en anglais et j'ai peur de ne pas tout comprendre quelqu'un peut me traduire le texte ci joint merci
The pictures shows where which cables attach to the laser head. It is to
consider at the laser is up to 170V - the parts at front and rear end are at
high voltage, that exhaust tunnel is isolated. The plate at the side and
the sensor can be removed, since this have no function in this structure. If
one is supplied the power pack with 230V the cathode immediately glow - this
could be recognize by the glowing in the cathode pot. So that the laser is
not damaged when first igniting (more badly or no contact at plugs to the
power pack), should one examine whether the cathode glows (look into the
tube from the front), but turn NOT the switch on I - the laser starts
otherwise!!! The cathode is supplied with approx. 2,8V and 1A alternating
current - thus the polarity is all the same. Tighten the nuts/mothers at the
cathodes with use of a second key- to hold against, otherwise ceramic(s)
breaks!!! The laser must be cooled even if no discharge is active (code
switches on O), since the cathode is heated. One turns the code switch on
- the ignition will be done within 40sec. It is to consider to start the
laser with low current - to avoid damage to the laser it should work with
low current for 60 - 90 seconds, then the current can be increased. After
switching off one should let the exhaust fan run for a certain time, so that
the laser cools down. So that the laser cannot be damaged by temperature
rise, the two Amp plugs have to be connected - without this contact the
inter-lock is not closed- this means no green led and no laserlight. In cose
of high temperature the inter-lock will be opened by this switch and the
laser will stop. The starter produces 4-6kv - it should be installed well
isolated, alos since up to 170V fit here.
The fan should be mounted this way that the hot air is removed from the tube
effective - this means you have to install the fan upon the laser exhaust
with a 10 or 20mm space between the exhaust and the fan. Use some soft
material (foam) to
fill the gap between the fan and the laser exhaust. Never istall the fan the
way that it blows towards the laser tube !!!
The hot air must be blown away from the exhaust !
