H.
Pulse Ratio: Pulse ratio is used in conjunction with mode E & H. It is the
length of time the machine welds in the MAIN OUTPUT current state in
relationship to the length of time the machine welds in BASE / BACK-
GROUND current. The range being variable between 15 & 85 %. i.e. Main
welding current 100A, Base current 40A. Machine can be set to weld at
100A for 60% of the cycle and 40A for the remainder.
AC & DC Pulse
I.
Frequency: The frequency of the welding arc; between 0.5 and 200 Hz.
AC & DC Pulse
J.
Base Current: Base current or background current is the secondary weld-
ing current used in pulse mode. (Refer to F above.)
AC & DC Pulse
K.
AC Balance: Adjusts the cleaning and penetration cycles of the AC arc to
assist penetration of the weld pool.
AC & AC Pulse
K.
Arc Force: Used to slightly increase the welding current to prevent the
welding rod sticking; used when a short arc is required normally on low
amps.
MMA (ARC)
L.
Slope Down Time: Slope down time is the time it takes for the weld to
decrease from the set welding current down to the crater fill current.
DC Standard TIG
M.
Crater Fill Current: Crater fill current is the low welding current required to
fill the weld pool/ crater at the end of the weld cycle. Primarily for use on
stainless steel.
DC Standard TIG
N.
Post Flow Gas Timer: Post flow time is the length of time that the welding
gas stays on for after welding. Prevents contamination to the weld pool.
