4.4.4 Air Cylinder Consumption
Cubic Feet of air per minute per inch of stroke length (each direction)
Use the table above to calculate the air used by the air cylinder.
Add 0.034 cubic foot per second (2CFM) of actual weld time to account for converter cooling air
per weld cycle.
Example:
3.0" 2000X aed actuator running at full pressure (100psi) and stroke length (4") at a cycle rate of
20 parts per minute = 0.0319 CFM per inch of stroke (from table) x 8" (total strokeis 4" down and
4" back) equals 0.2552 CFM per stroke.
Weld time is 1 second so: 0.034 x 1 = 0.034 CFM for cooling.
Add 0.2552 CFM for cylinder to 0.034 CFM for cooling equals 0.2892 CFM per cycle.
Multiply by 20 (parts per minute) for a total of 5.784 CFM.
The example
above is to be considered a worst case condition for a welder to run at.
The 2000Xf/aef welding system is unique since it’s pneumatics are used in a differential mode of
operation. For this reason, use the 100psi values from the above table to be on the conservative
side for sizing airflow, rather than on the actual force values. Be sure to add the converter cooling
value, 0.034.
