10 Preparing the Welding Head
Capacitor discharge with contact
‹
Make sure that you have inserted the pressure spring (accessory, order
no. 80-40-695) for the contact welding process and that the toggle switch
for solenoid is set to the OFF position .
‹
Set the lift to "Maximum" .
This ensures sufficient piston movement (spring deflection). If not observed,
you will obtain poor welding results.
