GAS PROTECTION
Depending on the material to be welded, gas protection may be necessary.
The gas flow must be set between 12L/min and 15L/min.
The following table lists the gases required depending on the inserts to be welded and their material. This table is given
as an indication, pre-weld tests are recommended.
Insert to be welded
Alu pulling ring
Stud,
aluminium insulation nail
Steel pulling ring
Stud,
steel insulation nail, etc.
Note :
In the case of welding aluminium, pure Argon (Ar) can be used instead of the 30% Argon-
Helium mixture (ArHe30%). Also, in the case of steel (Fe or FeCu) welding, it is possible to use
pure Argon (Ar) instead of 8% Argon-CO² mixture (ArCO² 8%). In both cases, the settings
pre-set by the Synergy are no longer guaranteed, and it may be necessary to switch to Manual Mode.
Do not set the torque over 5N.m when tightening the gas input coupling.
CONNECTING THE GUN TO THE POWER SOURCE
The connection and disconnection of the gun control connector to the power
source socket must only be done with the power source switched off.
The ring of the gun control connector must always be properly screwed to the
power source socket before starting the product.
PROCESS FOR WELDING AN INSERT WITH DRAWN ARC
Phase
Ignition
T (ms)
I (A) ≈80-150 A
Ignition : the insert (pull ring studs, etc.) is placed in contact with the supporting material. Pressing the trigger starts
the welding process: the power source sends current to the stud, the gun shaft rises slightly, A low-intensity electric arc
is then created.
Penetration and cleaning: This phase could also be called preheating. The power source regulates a current to
ensure a low-intensity arc, the heat generated by this arc allows:
- burning off impurities from the backing sheet (grease, oil, electrolytic zinc coating).
- to preheat the two pieces, and thus limiting the thermal impact of the welding arc, to improve the quality of the weld.
During this phase neither the insert, or the support plate, is melted. Also, this phase does not allow the zinc layer of a
galvanised plate to be removed.
The arc: the power source significantly increases the current to create a high-energy arc that creates a molten pool on
the support plate and causes the end of the insert to melt.
