OPERATING MANUAL
Pass 1, level 1
Move the cursor and enter values with the control knob.
• Amps: current at each level (using pulsed current,
this is high pulse current).
• Wire: Filler Wire Feed Rate (in IPM or CM per
minute, function not available).
• RPM: Rotation Speed
• LP Amps: Low Pulse Amperage, shown as
percentage of high pulse current.
• HPT: High Pulse Time Period, in seconds.
• LPT: Low Pulse Time Period, in seconds.
• HP RPM: rotation speed on high current pulse
(shown only when RPM STEP is turned ON). Can
be set at any percentage from 0–99 of the low
pulse speed listed RPM.
• LP Wire: Wire Step Function, index of wire feed
with pulsed current (not available).
• Level Time: the time during which these
parameters will be active in seconds.
• Time Remaining: as the tube size is input,
selection of RPM automatically calculates Total
(weld) Time.
• Time Remaining: automatically calculated once
Level Time is entered.
• Total Time: total time for weld in seconds. Enter
values and press Next soft key to go to Level 2.
Automatic parameters carry down through levels.
You can copy parameters from one level to the next by
pressing Next. Be careful when changing parameters at
one specic level so as not to impact other levels.
Example: You wish to change the amperage originally
programmed in Level 4 of a one pass weld. However,
other parameter changes occur in a subsequent level,
such as level 5 or 6. If you make the change in amperage
in Level 4 and press Next, you will automatically copy all
of the Program Level 4 values into Level 5. Therefore, it is
necessary to note any other changes that are occurring
in subsequent levels within the pass before modifying
any parameter in that pass. Please note that this is only
true for Level parameters within any given pass. For a
multi‐pass weld, once you move to a subsequent pass,
the parameters will not be copied from the previous
pass.
Pass 1, level 2
Move the cursor, enter values with the control knob and
press Next; or if no change is necessary, press Next.
Pass 1, level 3 to nal level
Continue moving through the screens for each level and
change parameters as needed.
