10.3. Initiation and maintenance of the arc welding process
TIG device 201P AC / DC converter is equipped with an ionizer enabling non-contact arc ignition. To ignite the arc mode dwutaktu must approach the
electrode to the workpiece at the distance of 2 millimeters and press the button to turn on the torch handle ionizer. If within 3 seconds without arc
ignition, ionizer off automatically. To re-enable ionizer release button on the handle and press it again. After the correct initiation of arc welding lead the
button pressed. Releasing the button on the handle causes the start of the current phase of descent and ending the welding process.
To ignite the arc mode czterotaktu must approach the electrode to the workpiece at the distance of 2 millimeters and press the button on the handle of
the torch to turn the ionizer. If within 3 seconds without arc ignition, ionizer off automatically. To re-enable ionizer release button on the handle and
press it again. After the correct arc is lit button can be released and welding lead to the slow button. To complete the welding press and release the
button on the handle.
ATTENTION !!
- When welding with alternating current (AC) current values ​ ​ i s low deposition of the oxides on the surface of the tungsten electrode. This can
cause problems with the arc ignition. In this case rub electrode of material welded or otherwise mechanically clean the tip electrode with an
oxide layer.
- Do not turn on the button at a distance greater than 2 mm from the work piece.
- Do not touch the electrode while pressing the button on the handle. Ionizer high voltage and the voltage in no-load condition occurring
when the electrode can cause electrical shock.
11. Before calling service,
In the event of malfunction of the unit, before sending welding for service, check the list of basic failures and try to remove them yourself.
Repair work may only be carried out after removing the plug from the wall socket.
Attention! The device is not sealed, and the user can remove the cover of the welding device in order to remove minor breakdowns.
symptoms
The power indicator is not lit, the fan does
not work, no output
Power light is on, the fan does not
work, no output voltage.
Power light is on, the fan is running,
problems with the arc is started
Remedy
1. Make sure the switch is in the ON position
2. Check the security on the network connection and
3. Remove the cover and check the connection of all electrical plug inside the device
1. Verify that the device has not been connected to the higher voltage. If so, connect to 230V
and turn again
2. The supply voltage is unstable and turns on the overvoltage protection. Turn off device for
2-3 minutes and then back
3. Short on and off switch may have been activated overvoltage protection. Turn off
device for 2-3 minutes and then back
4. there was other damage requiring repair by an authorized service
1. Check TIG replace wear parts if they are worn
