Standard Head 5-50 lbs. Pressure (Model 3020)
Maximum stroke is about l”. The head can be adjusted up and down on the column to accommodate different applications. The weld pressure is adjusted by use of the thumb screw on top of the head. Increased pressure means lower contact resistance so it may be necessary to increase the power setting of the power supply. Too little pressure will cause arcing and flash while too much pressure may deform the parts. Experimentally determine a high enough pressure that will not cause deformation. Electrode holders can be supplied for 1/8″, 3/16″ or 1/4″ diameter electrodes. Special sizes or tooling can also be supplied, please contact the factory.
