The microprocessor controlled stud welding unit PRO-D 2200 is designed for drawn arc and short cycle stud welding. Microprocessor control, continuous adjustment of welding current and time as well as constant current regulation ensure in connection with the high performance of the unit optimum welding results and repeatability. The unit is easily operated by the very robust rotary knob with a built-in push button, all functions and parameters are shown on a big display.
Pre-installed welding programms facilitate the choice of the right adjustment values for different welding tasks. Additionally, user specific welding programms 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 finished 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 to a PC.
Optionally, the unit can be equipped with a shielding gas module for welding with shielding gas for weld pool backing and with an automatic module to control the automatic stud feeder VBZ and an automatic welding gun.
The PRO-D 2200 can be supplied as multi-gun unit for the operation of two or four stud welding guns with different adjustment values for welding current and welding time. The multi-gun unit automatically detects which gun is used. All gun connections can be equipped with a shielding gas module. Alternatively, for the operation of up to four stud welding guns on one unit the external adapter box PRO-SPLIT is available as accessory.

• welding current continuously adjustable
• welding time continuously adjustable
• constant current regulation
• 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 type)
• 59 user-specific welding programms can be stored
• welding parameter monitoring and documentation
  - recording of welding current, welding time, welding energy and arc voltage 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): shielding gas module for welding with shielding gas for weld pool backing
• shielding gas pre- and post-flow time continuously adjustable (with option shielding gas module)
• optional (also retrofitable): automatic module to connect the automatic stud feeder VBZ and an automatic welding gun
• optional (also retrofitable): two or four gun connections
  - different adjustments for welding current and welding time
  - automatic detection of used gun
  - welding programme storage for each gun connection
  - weld counter for each gun connection
  - optional (also retrofitable): shielding gas module for each gun connection
• available as accessory: adapter box PRO-SPLIT
  - enables the operation of up to four stud welding guns with different adjustment values for welding current and welding time on one unit
  - automatic detection of used gun
  - welding programme storage for each gun connection
  - weld counter for each gun connection
  - with up to four shielding gas modules
• switch between standard and basic version with reduced range of functions for particularly easy operation
  Series PRO-D units can be switched to a basic version (protected by password entry). The basic version has a reduced range of functions for particularly easy operation. Only welding current, welding time and day counter can be set.
• suitable for through deck welding
• 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 through excess temperature
• phase monitoring
• automatic switch-off in case of excess temperature and phase failure
• protection of the unit in case of a fault on welding/control line cable and solenoid
• 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
• optimized for the operation on generators
• lifting eyes
• two swivel castors, two fixed castors
• robust, powder-coated metal housing
• stable fixing of welding cable sockets at own plug holder, prevents damage on housing caused by pulling of cable
