2.2 CURRENT
OUTPUT
NOTE
The following specifications will, in many cases, reference “User Defined”. User defined means
that the user can set up the actual programmable ranges and functionality of any given function.
For specification purposes this means that no actual function range can be given. Where
applicable only an absolute maximum or minimum are given.
1.
Range - 5 to 400 Amperes programmable. Programmable increments can be user
defined in units of 1 or 0.1 amperes.
2.
Type - Continuous or pulsed output DC Straight Polarity for GTAW (TIG) welding only.
3.
Regulation - Constant Current closed loop servo using second generation high frequency
(60 KHz) series switching regulation.
4.
Regulation Response - Response time for correction of current deviation is less than 500
microseconds. Pulsed mode rise time from background current to primary is 1.2 ampere
per microsecond.
5.
Regulation Tolerance - +/- 0.5% of programmed setting or +/- 1.0 ampere whichever is
greater.
2.3
ARC VOLTAGE and ARC VOLTAGE CONTROLLER SERVO
1.
Open Circuit Output Voltage - 61 VDC
2.
Maximum Output Voltage under load - 30 volts (measured at power supply, not at torch)
3.
Arc Voltage Controller Range - (measured at the torch)
Minimum - 5 VDC
Maximum - 25 VDC
Actual programmable range is user defined.
4.
AVC 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.
5.
AVC Motor Output Voltage Limit - 35 VDC
6.
Regulation - Closed Loop position servo using arc voltage measured at the torch. Intended
for DC permanent magnet type motors only.
7.
Regulation Tolerance - +/- 1% of program value or 0.1 VDC, whichever is greater.
Based on primary current only with no current pulsation. Measurable accuracy with the
current pulsing can be affected by the puddle growth and shrinkage.
8.
Regulation Response - Variable and programmable.
9.
Jogs - Motor servo provides for UP and DOWN motor jogs. Jog speeds are adjustable.
2.4
TRAVEL (torch rotation) SERVO
1.
Range - Programmable range is User defined by weld head type. Unit of measure (IPM or
RPM) and increments is user defined by weld head type.
2.
Regulation - Closed loop velocity servo using, as standard, analog tachometer feedback
of 0 to 5 VDC. Can be set up to regulate using digital tachometer or digital encoder
feedback. 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 +/- 0.1 IPM or RPM whichever is
greater. Based on maximum range being at least 10 IPM or RPM.
6.
Jogs - Motor servo provides for bi-directional (CW and CCW) motor jogs. Jog speeds are
adjustable.
2.5
WIRE FEED SERVO
1.
Range - Programmable range is User defined by weld head type. Unit of measure (IPM or
mm/min) also user defined by weld head type.
2.
Regulation - Closed loop velocity servo using, as standard, analog tachometer feedback
of 0 to 5 VDC. Can be set up to regulate using digital tachometer or digital encoder
feedback. Intended for DC permanent magnet type motors only.
