The cost-effective entry-level model F 4050 impresses with its high-quality features. A robust welded steel machine frame as well as the safety housing with protective shields and light curtain are standard equipment. Series PRO-C, PRO-I and PRO-D stud welding units as well as the stud welding heads KHA-200F and KKA-200F are applied.
The working area of the machine is 400 x 500 mm. It is suitable for different welding methods (capacitor discharge, short cycle and drawn arc stud welding). Even for untrained operators the F 4050 is easy to operate and to program and can be retooled very fast.

• working area X/Y: 400 x 500 mm
• welding range
  stud diameter 3-12 mm (Other diameters as well as special welding elements upon request as special production.)
• max. number of stud welding heads: 1
• max. operating speed of the X-/Y-axis: 6 m/min
• repeat positioning accuracy of the welded studs: +/- 0,2 mm
• fast and easy programming by operating software PRO-STUD (incl. DXF data converter)
  (DXF data import: The customer-specific DXF-data are automatically converted and transfered to the controller. Visualization of the program sequence.)
• very easy operation by PC with Windows 10, 17" monitor (optional as touchscreen), keyboard and mouse with ergonomic mounting; keypad at the front of the machine
• ample program memory
• welding parameter monitoring and documentation (by stud welding units PRO-C/PRO-I/PRO-D)
  - recording of welding current, welding time and arc voltage for each weld
  - recording of stud travel (lift, piston runtime, immersion depth) for each weld [only when an automatic welding head with travel measuring system is used]
  - comparison of the recorded welding parameters (actual values) to the parameters of a reference weld (set values) (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 16000 welding parameter sets (storage with date and time) with USB-interface for data transmission (welding parameter sets) to a PC
• automatic stud feeding
• very good accessibility of the machine (electrical cabinet is integrated in the machine frame)
• flexible positioning of the pneumatic clamps on the machine table
• short set-up and retooling times
• quick change system for welding heads
• free zero points (zero point shift)
• re-weld function with program continuation
• housing with light curtain or door (design as sliding, folding or lift door (if required also pneumatically))
  optional: housing with closed top as sound insulation housing
• high processing speed due to dynamic step motors with encoder
• premium axes with high-precision guides and threaded spindle warrant a maximum of precision and reliability
• inside slide mountings with sealing bands avoid damages to the drive caused by welding spatters, smoke and dust
• very robust and warp resistant welded steel machine frame
• machine table made from aluminium T-grooved plates with laminated fabric plates for electrical insulation and as wear protection
• ceramic stop pins on the X- and Y-zero line
• pneumatic working lift/welding head 80 mm (mechanic adjusting range through precision crank handle 50 mm)
• The machine is suitable for all stud welding methods.
  The following stud welding units and automatic stud welding heads can be used:
  PRO-C 1000/1500 = stud welding units for capacitor discharge stud welding (contact and gap method)
  PRO-I 1300/2200 = stud welding units for drawn arc and short cycle stud welding
  PRO-D 1600 = stud welding unit for drawn arc and short cycle stud welding
  KHA-200F with integrated travel measuring system = automatic stud welding head for capacitor discharge (gap and contact method), drawn arc and short cycle stud welding
  KKA-200F = automatic stud welding head for capacitor discharge stud welding (contact method)
• connection values
  electrical (mains supply, mains fuse external): 230 V/50 Hz, 16A
  pneumatical: ≥ 6 bar, unoiled, dry, clean

• fluid spraying device for targeted wetting of the welding point before welding for the welding head
• pneumatic single stud feeding, manual stud insertion (e.g. for feeding special studs (special geometries, overlong studs))
• stud switch for feeding studs with the same diameter but different lengths into one welding head
• pneumatic mass clamps standard
• pneumatic mass clamps aperture angle 90°
• mechanic mass clamps mounted on welding head
• pneumatic mass clamps mounted on welding head
• workpiece downholder for the welding head
• shielding gas equipment for the welding head
• side shelf for automatic stud feeder VBZ
