10.4.4 Crater – These values are used after the stop button is pressed for the time defined in
Crater Time. See SECTION 10.4.7.
10.4.5 Prepurge – This is the amount of time that the shielding gas solenoid will be open
after the start button is pushed but before the welding wire makes contact with the
work piece.
10.4.6 Start Time – This is the amount of time the Startup Parameters are active. This time begins
after the welding wire makes contact with the work piece and an arc is established.
10.4.7 Crater Time – This is the amount of time the weld process will continue after the stop button
has been pressed. During this time, the parameters defined in the Crater Weld default (See
SECTION 9.3.4) will be active.
10.4.8 Burnback – This is the amount of time that voltage remains applied to the welding circuit in
order to melt the welding wire a small amount. This eliminates the possibility of the welding
wire being stuck into the crater of the weld puddle.
The available boxes and their limits are updated dynamically from the Power Wave ® S350. The boxes
that appear vary depending on the welding mode. For example, Pulse will display Trim and UltimArc.
Non-synergic STT ® modes will display Peak, Background, Tailout and Hot Start. The limits for each
will be automatically configured. For modes that set a Voltage, like CV, the voltage will automatically
be set to the synergic default according to the power source. You can override this and set it as the
application requires.
