4.2. THICKNESS OF THE SUPPORT SHEET IN RELATION TO THE DIAMETER OF THE STUD
With the exception of pulling ring applications for bodywork removal, the thickness of the supporting sheet must not be less than ¼
of the diameter of the base of the insert in the case of steel, and ½ of the diameter in the case of aluminium.
Workpieces
(according to ISO 13918)
M5 copper plated steel stud
Insulation nail Ø2.5 in copper-plated steel
AlMg stud M4
4.3. PROTECTION OF THE WELD POOL
Depending on the material to be welded, gas protection may be necessary.
The table below lists the recommended gas to use depending on the workpiece and its material. These gases maximise the weld
strength and are the appropriate gases to use when the machine is operating in Synergic Mode (see §7.1).
This table is given as an indication, pre-weld tests are recommended.

Accessory to be used
If gas shielding is used, the flow rate should be set between 12 l and 15 l/min.
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, pure Argon (Ar) can be used instead of the 8% Argon-CO² mixture (ArCO² 8%). In both
cases, the welding characteristics of the synergies are no longer guaranteed, and it may be necessary to switch to Manual
Mode (see §7.2).
In all three cases, the welding characteristics of the synergies are no longer guaranteed, and it may be necessary to switch to Ma-
nual Mode (see §7.2).
Do not set the torque over 5Nm when tightening the gas input coupling.
4.4. POLARITY OF THE GUN
The polarity of the gun has an impact on the quality of the weld.
Depending on the type of part to be welded, and its material, it is recommended to connect the positive texas connector from the
gun to the + or - terminal of the power source. Below is a table showing the preferred polarity used by GYS.
