COMMON WELDING PROCEDURES

WARNING
MAKING A WELD
The serviceability of a product or structure utiliz-
ing the welding programs is and must be the
sole responsibility of the builder/user. Many
variables beyond the control of The Lincoln
Electric Company affect the results obtained in
applying these programs. These variables
include, but are not limited to, welding proce-
dure, plate chemistry and temperature, weld-
ment design, fabrication methods and service
requirements. The available range of a welding
program may not be suitable for all applications,
and the build/user is and must be solely respon-
sible for welding program selection.
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
R500 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 avaliable to use
with the POWER WAVE ® R500.
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 pro-
grammed into the POWER WAVE
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
adjust the voltage and current according to settings contained in
the POWER WAVE ® .
In non-synergic modes, the WFS control behaves like a conven-
tional 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 volt-
age.
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 nomi-
nal setting and is a good starting point for most conditions.
UltimArc™ Control
UltimArc™ Control allows the operator to vary the arc character-
istics. UltimArc™ Control is adjustable from –10.0 to +10.0
with a nominal setting of 0.0.
