SERRA SOLDADURA Equipment We Repair — By Category
SERRA SOLDADURA Product Lines We Repair
Our engineers are trained on the full SERRA SOLDADURA product range. Below are the major product families we service.
SERRA WeldControl Series
Advanced digital controllers managing arc parameters, temperature regulation, and weld quality feedback. Common faults include calibration drift in voltage sensing, encoder misalignment, and thermal sensor failures that cause inconsistent weld penetration and surface defects.
SERRA ServoRobot Integration
Servo-driven robotic welding positioning systems with real-time feedback loops. Typical repair issues involve servo motor bearing wear, incremental encoder faults, and loss of synchronisation between torch and workpiece positioning axes.
SERRA Power Supply Units
High-capacity DC and pulsed power supplies (200A-600A) for MIG, TIG, and stick welding. Failures often stem from capacitor degradation, rectifier bridge faults, inductor saturation, and cooling fan motor breakdowns leading to thermal shutdown.
SERRA Torch & Wire Feeder Systems
Motorised wire feeding units with spool sensors and burnback protection circuits. Common defects include stepper motor stalling, Hall effect sensor misalignment, and capacitive discharge circuit failures preventing proper arc initiation.
SERRA HMI & Process Controllers
Touchscreen interfaces and programmable logic modules for weld parameter storage and recipe management. Typical issues include display panel dead zones, firmware corruption, Ethernet port failures, and button matrix degradation causing intermittent input detection.
SERRA Sensor & Feedback Modules
Infrared temperature sensors, voltage dividers, and current-monitoring boards for closed-loop arc control. Repair involves sensor recalibration, PCB trace repair, optocoupler replacement, and signal conditioning circuit restoration.

Common SERRA SOLDADURA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SERRA SOLDADURA equipment arriving at our workshop.
- ✓Welding controller calibration drift and voltage offset — SERRA WeldControl boards rely on precision 16-bit ADC circuits. Extended operating hours, thermal cycling, and component ageing cause reference voltage regulators to drift, leading to +-2-5V measurement errors in arc voltage sensing. This degrades weld consistency and causes wire feed hunting.
- ✓Servo motor encoder misalignment and synchronisation loss — SERRA ServoRobot systems use incremental encoders coupled to stepper and brushless servo motors. Mechanical shock, vibration from welding arcs, or improper reassembly after maintenance causes encoder disc misalignment or quadrature signal phase shift, causing intermittent axis movement and weld seam deviation.
- ✓Capacitor bank failure and thermal shutdown cycling — SERRA PSU boards (250A-600A) use high-ripple electrolytic capacitors rated 400-450V. Industrial ambient temperatures, dust ingress, and continuous high-current switching degrade capacitor ESR within 3-5 years, causing output voltage sag and triggering over-temperature protection. Units cycle on/off every 2-10 minutes.
- ✓Wire feeder motor stalling and inconsistent wire feed rate — SERRA WF (Wire Feeder) stepper motors are prone to mechanical jam from spatter buildup or bearing wear. Additionally, stepper driver ICs (like Allegro A4988) on feeder PCBs fail under thermal stress, losing commutation sync and causing torque loss or complete stall even at 50% rated speed.
- ✓Touchscreen HMI panel dead zones and intermittent touchscreen response — SERRA HMI-7inch and HMI-10inch displays experience capacitive sensor degradation after 2-3 years of daily use in workshop environments. Humidity, thermal shock, and continuous vibration degrade the flexible interconnect and touch controller IC, creating unresponsive or 'ghost' touch areas.
- ✓Infrared temperature sensor drift and false over-temperature shutdown — SERRA Temp-Sensor-IR units drift due to lens contamination, internal optics misalignment, or signal conditioning amplifier offset voltage creep in the analogue front-end. This causes false readings (+-20-50 degC error), triggering unwanted thermal interlock shutdowns mid-weld.

Frequently Asked Questions — SERRA SOLDADURA Repairs
Do you repair SERRA SOLDADURA equipment anywhere in India?+
Yes. Synchronics repairs the full SERRA SOLDADURA product range — welding controllers, servo positioning systems, power supply units, wire feeders, HMI panels, and sensor modules. We offer PAN India door-step pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and 100+ other cities. All repairs and testing happen in our fully-equipped Vadodara, Gujarat facility.
My SERRA WeldControl unit shows voltage offset errors and inconsistent arc stability. How is this repaired?+
SERRA WeldControl boards drift due to aged reference voltage regulators and ADC calibration loss. Synchronics replaces the LM317 or TL431 reference IC, recalibrates the 16-bit ADC using precision voltage standards, reprograms EEPROM calibration tables, and validates +-0.5V accuracy on test rig before dispatch. Typical turnaround is 5-7 days.
Can you repair SERRA servo encoder faults and axis misalignment?+
Absolutely. SERRA ServoRobot encoders commonly misalign after mechanical shock or vibration. Our technicians perform optical realignment, validate quadrature signal phases using oscilloscopes, reprogram servo gains, and run full axis tracking tests. We guarantee < 0.05mm positioning error and smooth motion across all axes before return.
What is the typical repair cost and turnaround for SERRA PSU capacitor failure?+
SERRA 250A-600A power supplies often fail due to capacitor bank ESR degradation. Repair involves capacitor replacement, heatsink cleaning, solder joint reinforcement, and 4-hour full-load stress testing. Cost ranges ₹8,000-18,000 depending on PSU model and damage extent. Standard turnaround is 7-10 days from receipt.
Is my SERRA equipment still under warranty with Synchronics repairs?+
Yes. All Synchronics repairs come with a 12-month parts and labour warranty covering the same fault. However, warranty does not cover damage from improper installation, liquid spillage, or electrical surge. We recommend surge protection devices on all SERRA controller inputs for ongoing protection.
How do I send my SERRA SOLDADURA 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 SERRA SOLDADURA 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 SERRA SOLDADURA 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 SERRA SOLDADURA 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.
