COMMON WELDING PROCEDURES

Choose the electrode material, electrode size, shielding
gas, and process (GMAW, GMAW-P etc.) appropriate
for the material to be welded.
Select the weld mode that best matches the desired
welding process.
The standard weld set shipped with the POWER
WAVE® S350CE encompasses a wide range of
common processes that will meet most needs. If a
special weld mode is desired, contact the local Lincoln
Electric sales representative. All adjustments are made
through the user interface. Because of the different
configuration options your system may not have all of
the following adjustments.
See Accessories Section for Kits and Options available
to use with the POWER WAVE® S350CE.

Definition of Welding Modes

Non-Synergic Welding Modes
•
A Non-synergic welding mode requires all welding
process variables to be set by the operator.
Synergic Welding Modes
•
A Synergic welding mode offers the simplicity of
single knob control. The machine will select the
correct voltage and amperage based on the wire
feed speed (WFS) set by the operator.
Basic Welding Controls Weld Mode
Selecting a weld mode determines the output
characteristics of the Power Wave power source. Weld
modes are developed with a specific electrode material,
electrode size, and shielding gas. For a more complete
description of the weld modes programmed into the
Power Wave S350 CE at the factory, refer to the Weld
Set Reference Guide supplied with the machine or
available at www.powerwavesoftware.com.
Wire Feed Speed (WFS)
In synergic welding modes (synergic CV, GMAW-P),
WFS is the dominant control parameter. The user
adjusts WFS according to factors such as wire size,
penetration requirements, heat input, etc. The Power
Wave S350CE then uses the WFS setting to adjust the
voltage and current according to settings contained in
the Power Wave. In non-synergic modes, the WFS
control behaves like a conventional power source where
WFS and voltage are independent adjustments.
Therefore, to maintain proper arc characteristics, the
operator must adjust the voltage to compensate for any
changes made to the WFS.
Amps
In constant current modes, this control adjusts the
welding amperage.
Volts
In constant voltage modes, this control adjusts the
welding voltage.
Trim
In pulse synergic welding modes, the Trim setting
adjusts the arc length. Trim is adjustable from 0.50 to
1.50. 1.00 is the nominal setting and is a good starting
point for most conditions.
UltimArc™ Control
UltimArc™ Control allows the operator to vary the arc
characteristics. UltimArc™ Control is adjustable from –
10.0 to +10.0 with a nominal setting of 0.0.
SMAW (Stick) Welding
The welding current and Arc Force settings can be set
through a Power Feed 10M, LF45, LF45S or Power
Feed 25M wire feeder.
Alternatively an optional Stick / TIG UI (K2828-1) can be
installed into the power source to control these settings
locally.
In a SMAW (STICK mode), Arc Force can be adjusted.
It can be set to the lower range for a soft and less
penetrating arc characteristic (negative numeric values)
