Trim
description
Pulse welding controls the arc
length with 'Trim' instead of volt-
age. When trim (arc length) is
adjusted, the Power Wave auto-
matically recalculates the voltage,
current and time of each part of
the 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.

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 - 50 l/min or 0 - 105 cfh.
Units for gas flow are determined by the WFS units. English
units are cubic feet per hour (cfh) and metric units are
liters/min.
The gas type is based upon the weld mode chosen. For non-
synergic modes, the gas flow is set to Argon Mixes by
default. Rotate the center knob to select other gases.
The default gas for TIG is Argon, with the option for Helium
and Ar-He Mix.
When self shielded, stick or gouging processes are selected,
the gas flow rate shows “---“ and the gas type reads “gas
flow off”.
When the gun trigger is pulled, the display continues to show
actual gas flow rate while welding until another button is
pressed.
Alarms may be set to prevent welding with insufficient gas
flow using PowerWave Manager.
Calibration of the gas flow sensor is performed through the
set-up menu. A linear factor allows for an adjustment of
±10% of the factory setting (0.90 to 1.10).
