proper error code will be displayed on the front panel display. This
will typically happen if a weld is aborted early.
2.2.3
Lift distance and plunge distance parameters:
•
The mechanical parameters must be set on the respectively con-
nected weld gun NS40 and Light Duty drawn arc gun.
•
See the operating instructions of the corresponding weld gun for
the settings.
•
See the gun operating instructions and diagrams below respec-
tively for the guide values for the welding method.
Lift Settings
Maximum lift height (at +/-10% of rated input voltage, NS40 and
NS20HD): 2.5mm (0.1”).
Proper gun lift settings are as follows:
1.
All studs within the weld range are listed at 2mm lift and below.
2.
The plunge also needs to be appropiately set.
3.
When the E009 error appears the lift and plunge should be
reviewed.
4.
If the error is E004 or E007 it generally means no pilot arc.
5.
Check input voltage from unit control panel using F18 and read
capacitor voltage.
6.
If the lift capability is marginal, i.e. it lifts a low lift height, but fails
to lift at slightly higher lift height, consult your Nelson Rep.
2.2.4
Calibrate the gun drop time F31
It is recommended to calibrate the gun so that the welder understands
the gun drop time and delivers the precise main arc time programmed.
The calibration is a good practice when you exchange the gun, especial-
ly when you change process between short cycle mode (maximum
main arc time is 100 ms) and drawn arc (mininum main arc time is 100
ms), or change gun type or plunge dampener (shock absorber). Simply
go to F31, and shoot a stud. The actual gun speed is measured and the
actual drop time is saved in F31.
Note!
