MedWeld 5000 Technical Reference Manual
M-032170
(functions 30-34), if the turns ratio is changed, the weld
control will require the first 2 cycles of the next weld to
adjust the current.
CURRENT LIMIT MODE:
(AVERAGE) (PEAK)
This parameter specifies which method the control will use during
current limit processing.
•
If this parameter is set to PEAK, the fault is generated if the current
limit is exceeded during any one cycle.
•
If set to AVERAGE, the control adds the current read during each
cycle and divides by the number of cycles to determine average
current. The fault is generated only if the average current exceeds
the limit.
NOMINAL LINE VOLTAGE: nnn
(100–650)
The control use this parameter to establish a reference point for
determining the compensation required for line voltage fluctuations
when welding in the %I firing mode.
PULSE WIDTH LIMIT:
The output power level is determined by controlling the pulse width of
the high-frequency square wave. This setup parameter will let the
operator set the limit of the pulse width.
MILLI SEC ON TIME:
This value represents how long, in msec, the inverter fired during the
MFDC half-cycle to obtain the voltage or current required to make the
weld.
MILLI SEC OFF TIME:
This value represents how long, in msec, the inverter fired during the
MFDC half-cycle to obtain the voltage or current required to make the
weld.
OFFSET RESISTANCE:
In CHC, the resistance value of the work is detected by the weld control
to control the weld current. Offset resistance is used to determine the
resistance of the weld delivering components (such as the electrode tip
and shank).
LOW HEAT LEVEL:
The setup parameter LOW HEAT LEVEL is programmed as a % of the
total heat. For example, if the LOW HEAT LEVEL is set to 80%, when
the control fires and does not reach 80% heat, the weld control will
fault.
HEAT CYCLE LIMIT (0=SEAM): nn
(0–99)
