3. Motor Output Current Limit - User defined by weld head type in increments of
0.1 Amperes up to a maximum motor drive current limit of 4.0 Amperes.
4. Motor Output Voltage Limit - 35 VDC
5. Regulation Tolerance - +/- 2% of program value or +/- 1 inch, whichever is
greater. Based on maximum range being at least 100 IPM.
6. Jogs - Motor servo provides for bi-directional (FEED and RETRACT) motor jogs. Jog
speeds are Adjustable.
2.6 TORCH OSCILLATION and CROSS-SEAM STEERING SERVO
1. Range - User Defined by weld head type as to maximum programmable amplitude.
2. Regulation - Closed loop position servo using +/- 5 VDC feedback voltage for
position information. Feedback device varies with weld head model. Intended for DC
permanent magnet type motors only.
3. Motor Output Current Limit - User defined by weld head type in increments of
0.1 Amperes up to a maximum motor drive current limit of 4.0 Amperes.
4. Motor Output Voltage Limit - 35 VDC
5. Regulation Tolerance - +/- 1% of program value or 0.010 inches, whichever is greater.
Based solely on M-415 servo specification. Actual response speed and tolerance
performance can vary depending on the dynamic loads on the weld head. Consult the
weld head specification for each weld head tolerance.
6. Jogs - No jogs are provided. Oscillator is continually seeking desired position. Position
is based on input (steering) commands from steering devices (on Pendant and Display).
2.7 TIMING FUNCTIONS
1. Purge Time Range (pre and post) -
000 to 1000 seconds. User can define minimum programmable time.
2. Start Delay Time Range (Travel, Wire, AVC) -
00.0 to 100 seconds in increments of 0.1 seconds.
3. Stop Delay Time Range (Travel, Wire, AVC) -
00 to 100 seconds.
4. Upslope Time Range -
00.0 to 100 seconds. User can define minimum programmable time
5. Downslope Time Range -
00 to 100 seconds. In increments of 1 second
6. Weld Level Time Range (up to 99 levels) -
0000 to 10000 seconds.
7. Pulse Timing Range (Primary/Background) -
0.00 to 100 seconds in increments of 0.01 seconds.
8. Oscillator Timing Range (Dwells and Excursion) -
0.00 to 100 seconds in increments of 0.01 seconds.
9. Primary WF pulse delay -
0.00 to 100 seconds in increments of 0.01 seconds.
10. Timing Resolution -
+/- 0.01 seconds (all timing functions)
2.8 ARC STARTING
1. Starting Methods - Touch or RF (radio frequency)
2. Touch Start provides a smooth, consistent and tungsten inclusion free start with any weld
head that has an AVC. Touch and Retract speeds are user defined. User can set up for
single start attempt or multiple start attempt.
3. RF Starting provides a method of arc starting without the electrode touching the weld
surface. System is designed for best performance under the following conditions:
1. Minimum first level primary current - 5 Amperes (in Argon only)
2. Gases - Argon, 95/5 Argon/Hydrogen, Helium or Helium/Argon Mixes.
3. 1 atmosphere pressure. Consult factory for operation in pressure chambers.
4. Maximum arc gap - 0.156 inch (4 mm)
