age while welding. You will not be able to ad-
just amps/wire speed on the panel in synergic
mode since wire speed/amp control is routed
through the gun, but will still be able to fine
tune voltage on the panel if needed. Otherwise,
the synergic spool gun mode operates essen-
tially the same as the Synergic MIG mode.
7. Mode (Process) Selector. Select the desired
process by toggling the arrow button. Each
press of the button will advance and highlight
the next process to the right. Select between
the following processes: Standard MIG mode,
Synergic MIG mode, , Standard Spool Gun mode,
Synergic Spool Gun mode, AC Standard TIG
mode, AC Pulse TIG Mode, DC Standard TIG
mode, DC Pulse TIG mode, Standard Stick mode
and E6010 (Cellulosic) Stick mode.
In standard
MIG or Standard Spool gun modes, volts and
amps are controlled completely independent of
each other.
When Synergic MIG or Synergic
Spool gun mode is selected, the Synergic mode
LED will light above the synergic section to re-
mind you that the operation is synergic instead
of manual. In TIG mode, be sure to select the
work clamp location that is appropriate for AC or
DC. If using with cellulosic rods, such as E6010,
remember to adjust the arc force and hot start
modes and keep a short arc if possible.
8. Stick Arc Control Selector and VRD In stick
mode, there are 3 additional functions besides
Amp adjustment that the user has control over.
The first is the arc force percent. The arc force
percent will be represented in the left display
and is adjusted from 0
- 100%. This gauges the
amount of amp reaction, or boost, when the arc
voltage begins to drop below satisfactory levels
(< 20V)while welding. This helps to prevent the
arc from going out or the rod from sticking in the
puddle when the rod is held close to the puddle
while welding. The goal of arc force is to help
maintain overall wattage. The setting range of
arc force control is the % of available amperage
over and above the standard welding amperage
that the programming will boost the amperage
to maintain the arc. . It can also be used to help
increase penetration by
“ pushing into the pud-
dle ” when more heat is needed. This feature can
also be referred to as “ Arc Dig ” as it allows the
user to tightly control the arc without loosing
needed fluidity of the puddle. As a good starting
point, consider setting arc force for around 30
-
35%. If welding with a cellulosic rod, such as
E6011, more arc force will be needed. Begin at
50% and work up to 70% to maintain best arc per-
formance. If E6010 is required, though not recom-
mended due to possible arc stability questions,
settings of 70% or greater may be required. The
second adjustment is Hot Start %. This is similar
to arc force control as it boosts Amperage, but
different in the fact it is not arc length dependent.
The Hot Start boosts the Amps only at the start of
the arc, to help bring the weld and rod up to tem-
perature quickly, thereby reducing the effects of a
colder start which usually results in porosity and
poor fusion under the arc start area. It also helps
to reduce failed arc start attempts. The Hot Start
% setting is often referred to Hot Start Intensity, as
it adjusts how aggressive the Hot Start will be. A
good preliminary setting is anywhere between 30
-
50%. The third adjustment is Hot Start Time. This
adjustment simply is used to define how long the
Hot Start function stays engaged once the arc
strike occurs. For a starting point, adjust Hot Start
Time to .2 to .3 seconds, increasing or decreasing
from there, as needed.
HINT: Use more Hot Start
Time and Intensity for thicker metals and thicker
electrodes (rods)
. In the separate subsection, the
VRD represents a safety feature that allows the
OCV to be reduced. When the Voltage Reduction
Device (VRD) is selected, OCV is dropped below 20
Volts to reduce the chance of electrical shock
while welding stick in situations where the worker
may become grounded and become a potential
circuit path of the electricity. In some situations,
VRD is require to ensure the safety of the opera-
tor. VRD can in some cases make starting a little
more delayed or difficult.
9. Pedal/2T/4T selector. Press the button to select
one of the torch switch or pedal function modes.
Select 2T for simple press
- and - hold operation of
the torch switch. For 2T operation with the torch
switch: 1) Press and hold the switch to start the
arc and weld. Release the switch to cease welding.
Select 4T for advanced use of the sequencer con-
trols on the panel such as pre
- flow, post - flow, up
slope and down slope. To operate in 4T mode
with the torch switch/remote: 1) Press and re-
lease the switch to start arc. 2) The current will
begin to upslope to reach normal welding current.
3) Press and hold switch to begin the downslope
cycle to fill the crater. 4) Release switch to termi-
nate the arc. In 4T mode, if the puddle becomes
too hot, it can be cooled by lightly tapping the
switch to begin downslope and tapping again to
