13 Welding Parameters
13.1 Pre Gas
Pre gas flow can be set to a maximum
of 5 seconds, to allow gas flow before
Arc Start.
13.2 Hot Start
Only available in Stick MMA mode, Hot
Start will provide a current boost at the
start of the arc. The parameter can be
adjusted up to 70Amps which will add
to the preset welding current.
13.3 Ignition Current
While in 4 STEP latch mode the arc will
start and maintain the Ignition current
output until the trigger torch is released.
The IGNITION CURRENT can be more or
less than the WELD CURRENT setting.
Setting the IGNITION CURRENT high
can be useful for joint preheat.
13.4 Up Slope
The UP SLOPE time is the time taken
for the weld current to transition from
the IGNITION CURRENT value to WELD
CURRENT value. The time can be
adjusted from 0 to 15 seconds.
13.5 Welding Current
The setting for actual weld current.
13.6 Pulse Welding
Pulse welding allows the current to
be pulsed between two different
values, the frequency and ratio can be
adjusted. This feature can be used on
thin material.
13.6.1 Peak Current
Set the Peak current Amps.
13.6.2 Pulse Ratio
Set the ratio in % for the peak
current compared to the back
ground current. Range is 15%
to 85%.
13.6.3 Hertz
The frequency of the pulse can be
set, as number of pulses for second
(HERTZ) 0.5Hz to 200Hz.
13.6.4 Base Current
Set the Base current Amps.
