FIRST TIME CONTROL SETUP
SECTION B, PAGE 7
Enter this number as the AREA of CYLINDER in PROGRAM 979.
If you have another brand of intensifier cylinder, consult the
manufacturer or distributor to find the correct effective area of
the cylinder.
B5.4 ROCKER ARM WELDERS:
Rocker Arm welders take the force from the air cylinder
at the rear of the welder and multiply this force by the
leverage of the welder’s rocker arm system.
In the picture to the right, the calculation would be:
ELECTRODE FORCE = CYLINDER AREA X AIR PRESSURE X (A/B)
The CYLINDER AREA is the number as listed in the SINGLE PISTON table at
section B4.1.
EXAMPLE: The electrode force of a rocker arm welder with a 6” single-piston air
cylinder (28.3 in
2
) where A=18”, B = 24”, and the air pressure is 65psi would be
calculated as:
ELECTRODE FORCE = 28.3 X 65 X (18/24) = 1380 POUNDS
The SOLUTIONi has a system to calculate the electrode force after the leverage
of the welder is entered in section B9.
