PRO-C 1500 Capacitor Discharge Welding Machine , Inverter Type Stud Welding Equipment

PRO-C 1500 Inverter type Capacitor Discharge Stud Welding unit

Microprocessor Controlled Stud Welding

The microprocessor controlled stud welding unit PRO-C 1500 is designed for capacitor discharge stud welding. Microprocessor control, continuous adjustment of charging voltage as well as switchable capacitance ensure in connection with the high performance of the unit optimum welding results and repeatability. Extremely short charging times and thus quick welding sequences are accomplished through the electronically clocked inverter charging boards. The unit is easily operated by a very robust rotary knob with a built-in push button, all functions and parameters are shown on a big display.
Pre-installed welding programmes facilitate the choice of the right adjustment values for different welding tasks. Additionally, user specific welding programmes can be stored. The modular design of the unit allows the customer specific choice of the equipment features. All optional equipment features can be retrofitted.
The integrated welding parameter monitoring enables the quality control of the conducted welds. By default, the parameter sets of the last ten welds are stored. The optional available welding parameter memory allows the storage of 24500 welds and has an USB-interface for data transmission (welding parameter sets) to a PC.
Optionally, the unit can be equipped with an automatic module to control the automatic stud feeder VBZ and an automatic welding gun.
For the operation of up to four stud welding guns with different adjustment values for charging voltage and capacitance on one unit the external adapter box PRO-SPLIT is available as accessory. The adapter box PRO-SPLIT automatically detects which gun is used.

• charging voltage continuously adjustable
• short charging times and thus quick welding sequences through electronically clocked inverter charging boards
• switchable capacitance for optimal adaptation to different welding tasks
• easy operation by a very robust rotary knob with a built-in push button
• all functions and parameters are shown on a big display (display contrast adjustable)
• library with pre-installed welding programmes (selectable via stud diameter and material)
• 99 user-specific welding programmes can be stored
• welding parameter monitoring and documentation
  - recording of welding current and welding time for each weld
  - recording of stud travel (lift, piston runtime, immersion depth) for each weld [only when a welding gun resp. an automatic welding head with travel measuring system is used]
  - comparison of the recorded parameters to the parameters of a reference weld (tolerances adjustable)
  - in case of variances to the reference weld a warning is displayed or the unit is locked for further welds until the release by the operator (functionality can be switched off)
  - storage of the last ten welding parameter sets
  - optional (also retrofitable): welding parameter memory for the storage of 24500 welding parameter sets (storage with date and time) with USB-interface for data transmission (welding parameter sets) to a PC
• device lock (with pin code query) to avoid unwanted parameter adjustments
• authorization concept with different roles (password protected) for device lock as well as changes of basic settings and menu structure
• weld counter (display in main menu)
• optional (also retrofitable): automatic module to connect the automatic stud feeder VBZ and an automatic welding gun
• available as accessory: adapter box PRO-SPLIT
  - enables the operation of up to four stud welding guns with different adjustment values for charging voltage and capacitance on one unit

• charging voltage is not influenced by supply voltage variations
• low-loss charging of capacitors through electronically clocked inverter charging boards
• low thermal power loss
• functional test without welding current for lift adjustment for welding guns and heads (lift test)
• repeat cycle lock to avoid welding on an already welded welding element
• intelligent self-diagnosis system (display of an error code in case of an interference/failure)
• automatic function test after switch-on
• temperature control as protection against destruction caused by excess temperature
• automatic switch-off in case of excess temperature
• protection of the unit in case of a fault on welding/control line cable and solenoid
• optimal safety during welding through integrated safety switching
• highest operational reliability and high power-on time through exclusive use of high-quality components
• all functions and parameters are controlled by a fast and high-performance microprocessor
• CAN-Bus and Anybus for safe communication with higher-level controllers
• thermic controlled ventilator
• robust, powder-coated metal housing
• interface for data exchange with higher ranked control systems (CNC)
• stable fixing of welding cable sockets at own plug holder, prevents damage on housing caused by pulling of cable
