Installing Air Actuated Weld Heads
Solenoid valve/regulator assemblies which are separate from the weld head, such as the Unitek Peco
Models 80, 81, 82, or 88, should be mounted at a convenient location on the bench.
Connect the inlet port on the Air Valve (Soleno id) to a PROPERLY FILTERED AIR SUPPLY (65 psig
maximum). Use 0.25" O.D. x .0.17" I.D. plastic hose with a rated burst pressure of 250 psi to connect
the outlet ports of the solenoid/regulator assembly to the flow controls on the air cylinders. See figure 2-
4. Turn the regulator(s) fully counter-clockwise to insure minimum air pressure. Turn on the air supply.
Repair leaks if necessary.
Use of a lubricator with air heads is not recommended since it is assumed that the system will be
operated in a "clean" environment. Once every six months or every 1 million operations, whichever
occurs first, place two or three drops of light machine oil in the top of the air cylinder.
