CDM 2401 is a welding machine with extensive energy settings for capacitor discharge CD stud welding units, particularly suitable for thin, 0.5 mm sheets. Microcontroller, monitoring function, error code display, library function, process monitoring and RS232 interface.
Welding frequency: 20 to 40 pins/min (depends on application and pin diameter).
General Information
Applications
- Particularly suitable for thin sheets (≥ 0.5 mm)
Process variants
- Contact welding
- Remote welding
Equipment
- Automation (standard)
Advantages
Features
- Microcontroller - for precise process timing, optimum functional reliability and maximum operating convenience
- Function monitoring - automatic function test after switch-on; monitoring of all internal system functions
- Display for error codes - on the LCD display
- Stroke test - for gun with lift-off and welding heads
- Library function - 8 programmes (load voltages) can be stored; library with stored welding parameters; possibility of entering additional customer specifications; interface available in various languages display of load voltage in volts
- Process monitoring - recording and analysis of factors influencing the welding process via process-analysis factor (PAF); after each weld, the measured value is compared with the reference value
PAF; display of current and reference values automatic weld stop switchable, if limits are exceeded; selectable increasing limits; manual input of PAF value possible
- RS232 interface - for data output; date and time of day are stored; parameters of each weld are recorded
Structure
- Extremely easy to use
- Compact
- Robust - metal structure resistant to work in the factory or on the construction site
Safety
- With integrated mains filter (protected against voltage fluctuations)
- Ideal for workplaces with wide fluctuations in the main voltage - safe to work with a mains voltage fluctuating between 85 and 265 V (with wide energy adjustments) - can also be used with critical voltage fluctuations
- EMC test
- Recording of voltage peaks during welding
- Restart block - prevents welding on an already welded element
- Thermal monitoring of transformer and internal temperature of welder - automatic shutdown in the case of overheating
- Temperature regulated by a fan - reduces noise and dust in the welder (increased system reliability)
- Control unit is galvanically separated from the welding lines - high degree of functional safety
- Excellent protection against external interference
Welding
- Display: Infinite current adjustments (reversible load via a control button); easy monitoring of all functions via an LCD display; operations are managed by a large LCD display
- Powerful - built-in current reserves
- Electronic loading regulation - allows high rates
- Problem-free change of voltage polarity by reconnecting welding current and ground cables (polarity reversal)
- Use of special capacitors (developed for stud welding)
- Change of capacitance - 33.000 μF or 99,000 μF
