Pulse Sequencer Functions:
Table 4.
Percent Peak Current: This
functions sets the amount of time
the pulse waveform spends at the
peak current setting. This
function is set as a percentage of
the total time for the pulse cycle.
Pulses-Per-Second: Sets the
total number of pulse cycles per
second of time.
Percent Background Current:
Sets the background amperage of
the pulse waveform. Background
amperage is set as a percentage
of the peak current.
Main Amperage Control:
The main amperage control button is intended to be a
quick selection method to adjust the main amperage
setting. This function will allow users to quickly exit the
sequencer portion of the U/I, eliminating the need to cycle
through all possible sequencer functions to adjust the
main amperage or exit the sequencer menu.
This knob is also a multi-purpose command: see the
“Operating Instruction” section for a description of how to
use this command for parameter selection.
Displays:
The right meter displays the preset welding current (A)
before welding and the actual welding current during
welding, and the left meter shown the voltage (V) at the
output leads.
A flashing on both displays indicate that the value read is
the average value of the previous welding operation. This
feature shown the average value for 5seconds after every
welding time.
If a remote control is connected (the Remote LED is ON),
the left meter (A) indicates the preset and the actual
welding current following the instruction explained in the
“Remote LED” description above.
The dispays are used to indicate during setting of
parameters, the name and the value of them. Also are
used for menu indication and error codes displaing.
Memory Selection:
The memory function is designed to allow the operator to
save up to 9 specific welding procedures. This memory
button will have two functions:
1. Save memory settings
2. Recall
memory settings.
Selecting Memory Functions: Pressing the memory
button will allow the user to toggle between “saving” a
memory, “recalling” a memory or operating without using
a memory setting.
1. Pushing 1 time “M” icon, SAVE icon turned on.
2. Pushing 2 times “M” icon, RECALL icon turned on.
3. Pushing 3 times Icon and diplays turn off.
Saving Memory Settings:
In order to save process settings into a memory location it
is first necessary to press the memory button so that the
“memory save” icon is highlighted. Once highlighted, the
number on the screen will flash to indicate this number
can be changed by turning the control knob below, and
the voltage and amperage meters will say “MEM SET”.
Once the desired memory location has been selected
using the control knob, pressing and holding the memory
button for 3 seconds will save the settings in that location.
During the 3 second hold period the “memory save” icon
will flash. After 3 seconds the displays will show “MEM
SAVE”
OPERATION:
1. Press Memory button to highlight “Memory Save” icon;
2. Turn Control Knob to Select memory location;
3. Press and hold memory button for 3 seconds.
Recalling Memory Settings:
In order to recall process settings it is first necessary to
press the memory button so that the “memory recall” icon
is highlighted. Once highlighted, the number on the
screen will flash to indicate this number can be changed
by turning the control knob below, and the voltage and
amperage meters will say “MEM RECL”. Once the desired
memory location has been selected using the control
knob, pressing and holding the memory button for 3
seconds will recall the settings from that location. During
the 3 second hold period the “memory recall” icon will
flash. After 3 seconds the displays will show “RECL
MEM”
OPERATION:
1. Press Memory button to highlight “Memory Recall”
icon.
2. Turn Control Knob to Select memory location.
3. Press and hold memory button for 3 seconds.
