Electromagnetic Compatibility (Emc) - Lincoln Electric INVERTEC V160 Bedienungsanleitung

3. Press and hold the TIG torch trigger when the main
part of the weld is complete. The machine will now
decrease the output current at a controlled rate, or
downslope time, until the Crater current is reached.
This Crater current can be maintained as long or as
short as necessary.
This sequence has an automatic restart so welding
will continue after this step. This operation, 4-step
restart enabled, is the default setting from the
factory. If the weld is completely finished, use the
following sequence instead of step 3 described
above.
3A. Quickly press and release the TIG torch
trigger. The machine will now decrease the
output current at a controlled rate, or downslope
time, until the Crater current is reached and the
output of the machine is turned OFF. After the
arc is turned OFF the postflow time will start.
4. Release the TIG torch trigger. The output current
will again increase to the Welding current, like in
step 2, to continue welding. When the main part of
the weld is complete go to step 3.
As shown here, after the
TIG torch trigger is quickly
pressed and released from
step 3A, it is possible to
press and hold the TIG torch
trigger another time to end
the downslope time and
maintain the output current
at the Crater current. When
the TIG torch trigger is
released the output will
again increase to the
Welding current, like in step 4, to continue welding.
When the main part of the weld is complete go to step 3.

Electromagnetic Compatibility (EMC)

This machine has been designed in accordance with all relevant directives and standards. However, it may still generate
electromagnetic disturbances that can affect other systems like telecommunications (telephone, radio, and television) or
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand
this section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine.
This machine has been designed to operate in an industrial area. To operate in a domestic area it is
necessary to observe particular precautions to eliminate possible electromagnetic disturbances. The
operator must install and operate this equipment as described in this manual. If any electromagnetic
disturbances are detected the operator must put in place corrective actions to eliminate these disturbances
with, if necessary, assistance from Lincoln Electric.
Before installing the machine, the operator must check the work area for any devices that may malfunction because of
electromagnetic disturbances. Consider the following.
•
Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and the
machine.
•
Radio and/or television transmitters and receivers. Computers or computer controlled equipment.
•
Safety and control equipment for industrial processes. Equipment for calibration and measurement.
•
Personal medical devices like pacemakers and hearing aids.
•
Check the electromagnetic immunity for equipment operating in or near the work area. The operator must be sure
that all equipment in the area is compatible. This may require additional protection measures.
•
The dimensions of the work area to consider will depend on the construction of the area and other activities that are
taking place.
Consider the following guidelines to reduce electromagnetic emissions from the machine.
•
Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take
As shown here, again after
the TIG torch trigger is
quickly pressed and released
from step 3A, it is possible to
quickly press and release the
TIG torch trigger a second
time to end the downslope
time and stop welding.
Maintenance
For any maintenance or repair operations it is
recommended to contact the nearest technical service
center or Lincoln Electric.
performed by unauthorized service centers or personnel
will null and void the manufacturers warranty.
The frequency of the maintenance operations may vary
in accordance with the working environment. Any
noticeable damage should be reported immediately.
•
Check cables and connections integrity. Replace, if
necessary.
•
Keep clean the machine. Use a soft dry cloth to
clean the external case, especially the airflow inlet /
outlet louvers.
Do not open this machine and do not introduce anything
into its openings. Power supply must be disconnected
from the machine before each maintenance and service.
After each repair, perform proper tests to ensure safety.
