CARL CLOOS SCHWEISSTECHNIK Product Lines We Repair
Our engineers are trained on the full CARL CLOOS SCHWEISSTECHNIK product range. Below are the major product families we service.
Cloos Powersource Arc Power Sources
Inverter-based and conventional arc welding power sources (200A-600A) used in production welding lines. Common failures include IGBT module burnout, capacitor degradation, and control PCB faults affecting output stability and arc ignition.
Cloos Robotic Welding Controllers
PLC-based control modules for automated robotic welding cells with torch position feedback and seam tracking. Typical issues include encoder signal loss, proportional valve driver failures, and communication breakdowns between controller and servo amplifiers.
Cloos Torch Positioning Systems
Servo-driven torch height control and lateral positioning systems with sensor feedback loops. Repair focus includes stepper/servo motor failures, LVDT sensor drift, relay bank burnout, and analog signal conditioning PCB defects.
Cloos Welding Interface Modules
Communication nodes and gateway modules connecting welding power sources to factory MES and I/O terminals. Issues include RS485/Profibus transceiver failures, galvanic isolation transformer burnout, and firmware corruption affecting data logging.
Cloos Transformer-Rectifier Units
Heavy-duty transformer and diode bridge combinations for high-current DC welding. Faults include secondary diode short-circuits, transformer winding insulation breakdown, and filter capacitor explosion under reverse voltage stress.
Cloos Wire Feed Controllers
Speed and tension control boards for MIG/MAG wire feeding systems with real-time current feedback. Common failures are brushless motor drive IC failure, encoder pulse interpretation errors, and current sense amplifier drift.

Common CARL CLOOS SCHWEISSTECHNIK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CARL CLOOS SCHWEISSTECHNIK equipment arriving at our workshop.
- ✓IGBT module short-circuit in power source — Carl Cloos Powersource units operate at high switching frequencies (16-20 kHz). Thermal cycling, moisture ingress during humid monsoon seasons in Indian plants, and damp workshop environments cause junction degradation and catastrophic IGBT gate oxide breakdown, resulting in DC bus collapse.
- ✓Torch height control sensor loss of signal — Cloos Telegas and Tracer positioning systems use analog LVDT sensors near the welding arc. High-frequency electromagnetic noise from arc striking, connector corrosion in salt-laden coastal plants (Mumbai, Chennai), and vibration-induced solder crack failures on sensor PCBs cause intermittent or complete signal dropout.
- ✓Robotic controller communication timeout with servo amplifier — Carl Cloos Roboplan and Weldersys controllers communicate via hardwired analog or Profibus interfaces. Electromagnetic interference (EMI) from heavy induction heating nearby, loose terminal blocks, and corroded shielded cable connectors in high-vibration automotive welding lines cause cyclic communication loss and robot halt.
- ✓Arc power output voltage unstable during welding — Cloos Digital Power and Variotwin inverter units degrade in output voltage regulation due to capacitor bank ESR rise (electrolytic aging at 40-50°C ambient in Indian foundries), analog feedback amplifier drift, or MOSFET snubber network failure. Voltage ripple exceeds ±2V, causing weld bead inconsistency.
- ✓Wire feeder motor stalls under load — Carl Cloos FeedControl and TensionMatic boards driving brushless or DC motors fail when bearing wear increases friction, control IC PWM stage saturates due to gate drive voltage droop, or current sense resistor opens (metal film type reliability issue in dusty fabrication shops).
- ✓Welding sequence hang due to PLC program fault or RAM corruption — Cloos Roboplan and similar PLC-based controllers experience program memory corruption from low-voltage brown-out (typical during monsoon power dips in Indian industrial parks), repeated emergency stop button cycling, or battery-backed RAM cell wear after 5+ years. Robot freezes mid-sequence.

Frequently Asked Questions — CARL CLOOS SCHWEISSTECHNIK Repairs
Do you repair Carl Cloos Schweisstechnik equipment anywhere in India?+
Yes. Synchronics repairs the complete Carl Cloos Schweisstechnik product range — welding power sources, robotic controllers, torch positioning systems, wire feed controllers, and interface modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major cities. Centralized repair facility in Vadodara, Gujarat with 180+ engineers and full test benches for arc welding electronics.
What is typical turnaround time for Carl Cloos Powersource arc welder repair?+
Standard Carl Cloos power source repairs take 5-7 working days after receipt. Priority turnaround is 2-3 days if the fault is straightforward (e.g., blown contactor, capacitor replacement). Complex IGBT module failures or custom firmware re-flashing may take 10-14 days. We provide daily updates via email and offer same-day collection from your facility in Gujarat region.
Can Synchronics repair Carl Cloos robotic welding cell controllers that have Profibus or EtherCAT interfaces?+
Yes, absolutely. Synchronics has proven expertise repairing Cloos Roboplan and Weldersys controllers with both hardwired analog feedback and Profibus fieldbus protocols. Our engineers debug communication timeouts, re-terminate connectors to DIN standards, and validate repair using Profibus analyzers. We also work with Cloos firmware engineers on complex protocol stack issues if required.
Do you stock replacement parts for Carl Cloos welding equipment?+
Synchronics maintains a limited stock of high-reliability components — IGBT modules, filter capacitors, relays, connectors, and sensor elements common to Cloos power sources and controllers. For obsolete or OEM-specific Cloos parts, we source directly from authorized German distributors within 5-10 working days. We always recommend repair over replacement to preserve capital and maintain production schedules.
Our Carl Cloos torch height control system gives fault code E15. What does this mean and can you fix it?+
E15 on Cloos Telegas and Tracer systems typically indicates LVDT sensor signal loss or analog input conditioning failure. This is a common issue in high-vibration automotive welding lines. Synchronics diagnoses whether the fault is at the sensor end (cable break, connector corrosion) or at the controller PCB (input amplifier saturation, A/D converter drift). We repair or replace the faulty subsystem and calibrate sensor offset/span before return to ensure no re-occurrence.
How do I send my CARL CLOOS SCHWEISSTECHNIK unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a CARL CLOOS SCHWEISSTECHNIK drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on CARL CLOOS SCHWEISSTECHNIK repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your CARL CLOOS SCHWEISSTECHNIK unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
