4.3 Adjusting the C0 and C1 gun
The electrical and mechanical welding parameters are set
at the
power unit and on the welding gun.
Welding time
• The welding time depends on the stud speed. It is
adjusted indirectly
via the spring force. The greater the spring force is, the
higher the speed of the welding element and therefore the
shorter
the welding time.
The spring force is set with the adjusting knob (
Turning clockwise:
The spring force is increased, thereby reducing the
welding time.
Turning anticlockwise:
The spring force is reduced, thereby increasing the
welding time.
Note: To prevent damage to the adjusting mechanism,
never use force to turn the adjusting knob into its end
positions.
Procedure
• Find your material combination and the diameter of the welding
element in
table 4 - 1.
• Turn the adjusting knob until the spring force indicator on the
welding gun shows the value from the table.
