advice
:
n flat regime, a low value of the fine tuning enables a quick rise of the short cut current. Thus, the regime is dynamic and hot which allows welding in
position but has the drawback of generating more spatter. On the contrary, a high value of the fine tuning reduces the dynamism and cools the weld pool.
Note : The welding position is further facilitated by "speed short arc" arc transfer than"smooth" arc transfer.
n Pulsed mode , fine tuning adjusts the energy of the current pulse and optimize the drop detachment.
Specifically, if fine projections detach from the wire, reduce the fine tuning, if rather large drops off, increase the fine tuning.

STRIKING ADJUSTMENT
The striking adjustment is accessible in the menu SETUP of the M G page.
Note: the striking is the 2 phase of the welding cycle.
The striking of every synergy is by default optimal in most of the application cases. However, in few very specific application cases, the user may want to
modify the striking characteristics.
Tuning parameters of striking:
K = Variable coefficient de -10 / 0 / +10
Name of the parameter
Description
Striking low wire advance K Allows modifying the low wire advance before striking.
Striking current K Allows tuning the striking current energy.
Striking transition energy K
Allows tuning the arc energy during the transit between the arc striking and the first
regime of the welding cycle.
WARNING
The user is responsible for the eventual dysfunction which a modification of the striking parameters may cause.

USER SYNERGIES
The User Synergies Menu is accessible from the homepage. This function of the power source allows the user to create their own synergies from the
existing ones.
From the synergy bar, lo
cated on the top of the screen as in the M G menu, choose an existing synergy by selecting the following parameters: metal,
diameter, gas, arc transfer. Choose those parameters as close as possible from the user synergy you want to create.
Once the parameters are selected, press the button User Synergy Creation:
1. The first step is the selection of the synergy points that will serve as support for the new synergic curves. Select at least 2 points, then validate.
2.
The second st
ep is the modification of the selected points, the addition of new points or the suppression of existing points.
Select a point among the list, press on “edit”. See below the settable parameters:
-Wire speed (m/min) : to create a new point, change this value and press the add point button.
-Arc length
-Fine tuning
-Thickness (mm)
- (A)
-U (V)
-Striking adjustment
The tuning of those parameters allows you adjusting the User Synergy according to your needs.
On this schematic example of a synergic curve, 4 points are
selected in order to create the user synergy.
The user added 3 points on the 4 support points by
setting the adjustable parameters for new values of the
wire speed.
