CLOOS SCHWEIS STEHNIK Product Lines We Repair
Our engineers are trained on the full CLOOS SCHWEIS STEHNIK product range. Below are the major product families we service.
CLOOS Arc Voltage Regulators (AVR) Series
Precision feedback control modules regulating welding arc voltage in MIG/MAG and TIG processes. Common failures include voltage sensor drift, proportional solenoid malfunction, and amplifier board failures causing inconsistent weld penetration.
CLOOS Wire Feed Motor Controls
DC motor control electronics for synchronized wire feed in robotic welding cells. Issues include PWM inverter failures, encoder feedback loss, and thermal overload trips during high-duty-cycle fabrication runs.
CLOOS Robotic Welding Integration Modules
Interface electronics bridging welding power sources to robot controllers via IO expansion cards and analog signal conditioning. Failures manifest as lost communication signals, incorrect torch positioning feedback, and sync errors with robot motion.
CLOOS Power Source Logic Boards
Central control PCBs managing weld parameter sequencing, process selection, and fault diagnostics in CLOOS welding machines. Common defects: capacitor aging, relay contact corrosion, microprocessor brownout, and memory chip failures.
CLOOS Thermal Management Modules
Cooling circuit controllers and temperature sensors for high-amperage welding operations. Failures include thermostat malfunction, pump control relay sticking, and temperature sensor signal noise causing false thermal shutdown.

Common CLOOS SCHWEIS STEHNIK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CLOOS SCHWEIS STEHNIK equipment arriving at our workshop.
- ✓Inconsistent arc voltage with intermittent dropout — CLOOS arc voltage feedback sensor becomes contaminated by spatter or suffers capacitive coupling noise in high-EMI shop floor environments. Proportional solenoid inside regulator develops intermittent electrical contact, creating momentary feedback loss.
- ✓Wire feeder motor stalls or runs erratically — CLOOS feeddrive PWM inverter stage suffers FET or IGBT gate driver failure. Encoder feedback loop develops intermittent open circuit or Hall sensor signal degradation, disrupting closed-loop speed regulation.
- ✓No communication between robot and CLOOS welding source — CLOOS ROBOT-LINK interface module RS485 transceiver failure or CAN bus termination resistor open circuit. Analog signal conditioning amplifiers in torch height control circuit saturate or lose offset calibration.
- ✓Welding machine enters continuous thermal shutdown fault — CLOOS thermostat module develops false trigger due to sensor noise, cold-junction temperature drift, or water coolant flow sensor blockage mimicking overheat condition. Analog comparator threshold drifts with component aging.
- ✓Microprocessor malfunction showing corrupt parameter memory — CLOOS logic board EEPROM or flash memory develops read errors due to power supply brownout events during grid fluctuations common in Indian industrial areas. Boot code corruption or watchdog timer resets.
- ✓Erratic parameter selection and mode switching — CLOOS control panel interface PCB develops contact wear on membrane switch membrane or push-button lateral contacts accumulate conductive corrosion. Multiplexer IC in microprocessor I/O expansion stage fails intermittently.

Frequently Asked Questions — CLOOS SCHWEIS STEHNIK Repairs
Do you repair CLOOS SCHWEIS STEHNIK equipment anywhere in India?+
Yes. Synchronics repairs the complete CLOOS SCHWEIS STEHNIK product range including arc voltage regulators, wire feed controllers, robotic integration modules, power source logic boards, and thermal management systems. We offer pan-India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Jaipur, and all major industrial cities. All repairs handled at our fully equipped facility in Vadodara, Gujarat.
How do I troubleshoot CLOOS welding source communication loss with my robot controller?+
First, verify the CAN bus or RS485 cable integrity and termination resistance (120 ohms) at both ends. Check for loose connectors and corrosion on CLOOS ROBOT-LINK interface module. Synchronics can test your interface board's differential drivers, isolation optocouplers, and signal conditioning circuits in-house. We provide diagnostic oscilloscope traces and recommend firmware updates if applicable. Same-day turnaround available for interface module replacement.
What is the typical turnaround time for CLOOS arc voltage regulator repair?+
Standard CLOOS AVR repair at Synchronics takes 5-7 working days including component diagnosis, parts replacement, calibration, and full load testing. Emergency express service available for critical production downtime — we prioritize arc voltage controller faults with 48-hour turnaround if parts are in stock. We notify you immediately if rare CLOOS components require factory sourcing from Germany.
Can Synchronics repair water-damaged CLOOS feeddrive motor controllers?+
Yes. CLOOS feeddrive controllers exposed to coolant mist or humidity require careful moisture removal and component evaluation. Synchronics performs ultrasonic cleaning, thermal cycling in controlled chambers, and selective component replacement for corroded inverter FETs, capacitors, and relay contacts. We verify insulation integrity via megger testing and functional validation before return. Conformal coating reapplication available for improved environmental protection.
Do you stock CLOOS replacement components or only repair boards?+
Synchronics maintains a dedicated inventory of high-failure CLOOS components including proportional solenoid driver transistors, arc feedback sensor amplifier ICs, thermal comparator modules, and encoder signal conditioning boards. For rare or obsolete CLOOS parts, we provide authorized distributor sourcing and expedited import logistics from Germany. We also offer refurbished CLOOS module exchange programs to minimize your downtime during major repairs.
How do I send my CLOOS SCHWEIS STEHNIK 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 CLOOS SCHWEIS STEHNIK 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 CLOOS SCHWEIS STEHNIK 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 CLOOS SCHWEIS STEHNIK 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.
