L204-4608-NA  PRODUCTION SPOT WELDER - continued

•    Air operated, lubrication free cylinder, eliminates oil mist and protects the environment
•    Electrode force adjustment with air filter reducer & gauge, located inside of the spot welder in protected position, with semi-automatic drainage system
•    Electrode speed control valves, shock absorber for end of stroke and air discharge silencers keep noise to a minimum
•    Epoxy coated transformer
•    Water cooled transformer, arms. electrode-holder and electrodes
•    Built-in microprocessor welding control located in protected position
•    Two-state electric foot switch, that besides its normal use in automatic and single spot mode, allows the operator to bring the pieces together and to weld these only when correctly positioned (operation for which the foot operated model was absolutely required.)
•    Pre-arrangement for the connection of a second electric two-stage foot switch L204-7028-4.  The addition of the second foot switch allows  recall of two different adjustments of time and current, required when different kinds of welding are to be performed on the same piece.

In summary,  this may all sound complex, but what it really means is that this is a very good welder.  It gives continuously good welds and is simple to operate.  We can’t say enough about this welder.
 ABOUT THE MICROPROCESSOR WELDING CONTROL:
•    Synchronous control with thryristor; insulated water  cooling and over temperature protection
•    Phase shift control for welding current set up
•    Slope and pulse functions
•    Twin presetting for time and current recallable by two independent foot switches
•    Friendly programming by means of four buttons
•    Single and automatic repeat modes
•    Surface condition compensation function of welding of oxidized    sheets and rods
•    First phase shift delay adjustment to obtain the best balance of line current
•    Auto-retain disabling for foot operated welding units
