• Close slide smoothly to the set adjustment pressure.
When the prescribed revolving bead height has been reached, reduce pressure. For this
purpose, move the valve lever to the position „pressure-less“ until the desired heating up
pressure is built up (heating up pressure = approx. 10% of the adjustment pressure).The
heating up time starts now. Press the stop watch and compare the actual time with the
nominal time taken from the table.
• After expiration of the heating up time, open the slide, remove the heating element as
quickly as possible, put it into the heat protective box and close the slide smoothly.
The maximum time frame for this process is predetermined by the value for the change-
over time taken from the table.
• When the welding pressure has been built up, press the stop-watch and keep the control
lever for approximately 10s on the position „pressure“ so that the hydraulic accumulator can
be filled. During the cooling down period re-adjust pressure, if necessary (the pressure for
cooling down is the same as the set adjustment pressure).
• After expiration of the cooling down period, release pressure, remove the welded part and
open the slide.
