PIPEFAB™ WELDING SYSTEM OPERATION
Start Time – Controls the WFS and voltage for a specified �me at the end of the weld a�er the trigger is
released. During the Crater �me, the machine will ramp from the Weld Procedure to the Crater
Procedure.
S�ck – SMAW weld process, uses either a so� 7018 or crisp 6010 electrode.
Synergic – Use of pre-programmed parameters to determine the needed se�ngs at a specific wire feed
speed.
TIG – GTAW weld process, uses either HF or Touch Start weld mode to begin welding.
Trim – Adjusts the arc length.
FIGURE B.1
Ul�marc – Ul�marc regulate the focus or shape of the arc. Values greater than 0.0 increase the pulse
frequency while decreasing the background current, resul�ng in a �ght, s�ff arc best for high speed
sheet metal welding. Values less than 0.0 decrease the pulse frequency while increasing the background
current, for a so� arc good for out-of-posi�on welding. The MIG mode will determine if Ul�marc is
used.

Wire Diameter – Selec�on of wire size for MIG and FCAW processes.
Wire Type – Selec�on of wire materials for MIG processes.
