Capacitor Discharge (CD) Stud Welder - CDi 3102

Capacitor Discharge (CD) Stud Welder - CDi 3102

DESCRIPTION

Unbeatable new power pack

  • With efficient inverter-capacitor charging technology
  • Enormous time and energy savings (30 % less energy!)
  • Highest cycle sequence of its class (up to 40 studs/min.)
  • 20% energy reserve due to 220 V charging voltage
  • Simple operation & minimal weight (20% lighter than previous model)
  • Extreme long life due to robust and functional industrial design

Highest level of quality and safety

  • IP 23 - Highest possible protection of its class
  • Capacitor formation recorded - Quality control for consistent capacitor quality through automateed formation
  • Shock-proof capacitor battery - No contact of the capacitors to the device housing; sparkover (short cicuit) is therefore not possible!
  • Cooling channel - Protects the electronic components from getting soiled. Ideal cooling of the inverter charging p.c. board for high sequence cycles.
Mild steel

Brass
M3 to M10 - #4 to 7/16"
GENERAL INFORMATION
Application
  • Especially suitable for thin sheets (at least 0.5 mm)
Process variants
  • Contact welding
  • Gap welding
ADVANTAGES
Features
  • Microcontroller – for precise process times, optimal functional reliability and maximum operating convenience
  • Function monitoring – automatic function test following power-up; monitoring of all internal system functions
  • Display of error codes – on digital display
  • Library function – automatic specification of charging voltage through selection of stud diameter according to welding range; fine adjustment via arrow keys
Structure
  • Extremely easy to operate
  • Compact
  • Robust - Powder coated steel housing withstands rough treatment in shop and on site
Safety
  • With integrated mains filter (protection against voltage peaks)
  • Optimal for construction sites with large mains voltage fluctuations – use even with critical voltage supply (- 25% + 20%)
  • EMC test (DIN EN 60974-10)
  • High-voltage test with log (DIN EN 60974-1)
  • Logged capacitor forming for quality control of the stud welding capacitors
  • Self-forming capacitors provide a longer life period and higher reliability
  • Retriggering lock-out – prevents welding on a welding element that has already been set
  • Thermal monitoring of charging unit and internal temperature of stud welding unit - automatic shutdown in case of overheating
  • Temperature controlled cooling fan – reduces noise and dust in the stud welding unit (greater system reliability)
  • Optimal protection against external interferences
  • IP-code: IP 23
Welding
  • Display – infinitely adjustable power setting (charge reversal via set-point switch); easy monitoring of all functions via LED displays
  • Powerful – built-in power reserves
  • Trouble-free changing of welding voltage polarity possible by reconnecting welding current and ground cables
  • Use of special capacitors (developed for stud welding)
