Trim
Pulse welding controls the arc length
with 'Trim' instead of voltage.
When trim (arc length) is adjusted,
the Power Wave automatically
recalculates the voltage, current and
time of each part ofthe pulse
waveform for the best
result. Trim adjusts the arc length and ranges from 0.50 to 1.50. Increasing
the trim value increases the arc length, while decreasing the trim value
decreases the arc length.
A. Trim.50 Arc length start
B. Trim 1.00 Arc length Medium
C. Trim 1.50 Arc length Long
Gas Flow Sensor Kit Operation
The K3338-1 Shielding Gas Flow Sensor is a precision,
solid state device for measuring gas flow.
To display the actual gas flow, press the left button to
select the shielding gas LED and then press the gas
purge button. To display gas flow while welding, change
P.3 in the set-up menu to “Show Gas Flow Rate.”
When selected, the actual gas flow and gas type are
displayed. The gas flow rate is display in xx.x for either
cfh or l/min. The flow rate range is 0-28 l/min.
Units for gas flow are selected with P.42, “Gas Flow
Units,” in the set-up menu. English units are cubic feet
per hour (cfh) and metric units are liters/min (l\min).
By default, the gas type is set to 100% Argon. The gas
type is a global setting and is only used to determine the
gas flow rate. It will not change based on the weld mode
selected. It can only be changed by hitting the left button
until the “Gas Type” selection is shown, and then
rotating the center knob.
Selecting a Weld Mode
Weld modes may be selected by mode number or
through a search function.
To select a weld mode:
1. Press the left button until the Weld Mode Menu LED
illuminates.
2. Rotate the center knob to select the weld mode.
To enter the search function:
1. Rotate the center knob until “Weld Mode Search” is
displayed and then press the right button.
2. Rotate the center knob to select the wire material.
Press the right button to accept and the left button
to cancel.
3. Rotate the center knob to select the wire size. Press
the right button to accept and the left button to
cancel.
4. Rotate the center knob to make the final selection
about the process, gas type and waveform. Press
the right button to accept and the left button to
cancel.
