Welding pressure
Press the lever locking mechanism (12) to the side and at the same time rotate the lever for welding
A
pressure (9) upwards. Manually loosen the locking screw (11). Using the adjusting screw for welding
pressure (10) adjust the clamping arm (31) to maximum opening. Tension the clamping arm (31) using
the lever for welding pressure (9).
Insert the test strips (lower and upper membranes) of the material to be welded between the lower drive/
B
pressure roller (20) and the upper drive/pressure roller (21).
Turn the adjustment screw (10) until the drive/pressure rollers (20/21) lightly touch the material to be
welded.
