Description
seamdata is used to control the start and end of the weld. seamdata
is also used if the process is restarted after a welding operation has
been interrupted.
The time (in seconds) it takes to fill the gas lines and the welding
gun with protective gas, also called "gas purging".
The time (in seconds) it takes to pre-flow the weld object with pro-
tective gas, also called "gas pre-flow".
Not selected – Select weld parameters during ignition phase
manually
Selected – Use the parameters from the Weld tab. This is the default
mode.
Weld list number defines the shape and characteristics of the weld
using eight active slots for selection of various processes, wire type,
and parameters. The characteristics of a weld list number generally
implement the process: GMAW, SMAW, SAW, GTAW, FCAW, etc.
Also known as a schedule. For more details about the particulars
of each weld list number, see the front panel of the welder.
Term used to represent wire feed speed. In MIG mode, wire feed
setting is independent of voltage setting. In pulse and Accu-pulse,
adjusting wire feed also increases power level of wire electrode (one
knob control).
Voltage sets the voltage reference for the weld.
In short circuit GMAW welding, an increase in inductance will de-
crease the number of short circuit transfers per second (provided
no other changes are made) and increase arc-on time. The increased
arc-on time makes the welding puddle more fluid.
Refers to the shape of the volt-amp curve. Varying the amount of
slope in the welding circuit will change the amount of short-circuit
current and rate of response from the power source.
Distance from end of wire electrode to weld pool.
Term used to represent arc length adjustments in pulse programs.
Increasing Arc Adjust increases the actual arc length. Likewise,
decreasing Arc Adjust shortens arc length. Arc Adjust is re-
placed by volts in MIG programs.
Allows setting of inductance and slope in MIG mode. In pulse and
Accu-pulse modes, this adjustment changes the arc characteristics
by adjusting the preprogrammed factory pulse settings.
