COMPUTER WELD Product Lines We Repair
Our engineers are trained on the full COMPUTER WELD product range. Below are the major product families we service.
Synergic MIG/MAG Control Units
Computer Weld's flagship synergic welding controllers that automatically adjust voltage and wire feed for consistent penetration. Common failures include thyristor short-circuits, arc voltage sensor failures, and wire speed potentiometer drift causing poor bead quality.
Pulse Arc Management Electronics
Advanced pulsed arc systems for precision joining of thin-section metals and aluminium. Repair challenges include oscillator circuit failures, peak/base current regulation faults, and frequency instability causing inconsistent pulse patterns.
Arc Voltage Regulation Boards
Closed-loop feedback units that maintain constant arc voltage during welding. Common faults: capacitor dry-outs affecting voltage stability, op-amp failures in feedback amplifiers, and calibration loss requiring re-tuning against reference standards.
Wire Feed Speed Controllers
Precision servo boards controlling wire feed rate with real-time arc stability feedback. Typical repairs involve stepper motor driver failures, speed sensor calibration issues, and PWM circuit board corrosion in humid manufacturing environments.
Power Supply Rectifier Modules
Three-phase to DC conversion and power distribution for welding sources. Failure modes include diode bridge burnout, capacitor bank failures, and gate drive circuit faults in IGBT-based rectifiers causing voltage collapse.

Common COMPUTER WELD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMPUTER WELD equipment arriving at our workshop.
- ✓No output voltage or weak arc voltage — Computer Weld's main DC bus capacitor bank degrades over 8-10 years in high-temperature foundry and fabrication shops, or thyristor gate drive circuit fails due to solder joint cracks in vibration-prone environments. Arc voltage feedback sensor may also drift out of calibration.
- ✓Inconsistent wire feed or hunting — Computer Weld synergic controllers use analog feedback loops to match wire speed to arc conditions. Potentiometer drift on speed reference, stepper motor driver IC failure, or loose PWM timing adjustment causes oscillating feed rates and poor bead profile consistency in production runs.
- ✓Thyristor or IGBT short circuit — Computer Weld power boards operate at high switching frequencies (10-20 kHz) in welding current regulation. Gate degradation from voltage spikes, moisture ingress in conformal coating, or undersized snubber networks cause catastrophic gate-source shorts and complete loss of welding output.
- ✓Arc voltage jumps or instability — Computer Weld's feedback loop relies on analog arc voltage sensing. Burned-out feedback amplifier, high-frequency noise coupling into the sensor signal, or corroded cable connector at the welding torch contact cause arc voltage regulation to oscillate, resulting in spatter and weak joints.
- ✓Fault code display or LED errors — Computer Weld control boards include onboard diagnostics that flag over-current, over-temperature, or phase loss. Sensor failures (thermistor open-circuit, phase-loss relay chatter), analog-to-digital converter noise, or firmware calibration drift trigger false alarms and machine lockouts.
- ✓Burned resistors or capacitors — High-current welding operations in Indian automotive and shipbuilding plants subject Computer Weld boards to extreme thermal stress. Undersized current-limiting resistors, dried-out electrolytic capacitors, or inadequate heatsinking cause repeated burn-out cycles, especially in un-cooled welding booths above 40°C ambient.

Frequently Asked Questions — COMPUTER WELD Repairs
Do you repair Computer Weld equipment anywhere in India?+
Yes. Synchronics is the authorized independent service partner for Computer Weld welding electronics across India. We pick up failed units from your manufacturing facility in Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, Ludhiana, and all metros and tier-2 cities. All repairs are done at our 10,000 sq ft facility in Vadodara, Gujarat, with 48-72 hour turnaround for most faults.
What Computer Weld products does Synchronics repair?+
We repair the complete Computer Weld industrial electronics range: synergic MIG/MAG controllers, pulse arc management systems, arc voltage regulation boards, wire feed speed controllers, and power supply rectifier modules. We also repair Computer Weld torch contact tips, cable assemblies, and sensor harnesses. If your Computer Weld welding source isn't welding reliably, Synchronics can diagnose and fix it.
How do you handle Computer Weld arc voltage calibration after repair?+
Computer Weld synergic systems require precise arc voltage and wire speed calibration to maintain weld pool consistency. After replacing failed feedback components or amplifiers, Synchronics uses precision multimeters and a calibrated shielded test load to confirm arc voltage output is within ±2% of setpoint across the entire range. We provide calibration certificates and setup guides so your operators can verify performance in-house.
Why does my Computer Weld welding source keep losing voltage during long production runs?+
Computer Weld's power bus capacitor banks are the first casualty in high-ambient-temperature welding shops. When foundries or fabrication yards exceed 40-45°C, capacitor life drops dramatically. Synchronics measures capacitor ESR and leakage current; if values exceed spec, we replace the entire bank with industrial-rated units rated to 85°C. We also check the main rectifier diodes and thyristors for forward voltage rise, which indicates imminent failure and reduces voltage under full welding current.
Can Synchronics repair Computer Weld boards that show fault codes on the digital display?+
Absolutely. Computer Weld control boards emit fault codes for over-current, over-temperature, phase loss, and sensor failures. Synchronics isolates the root cause—burnt thermistor, failed phase-relay, noisy sensor signal, or defective analog-to-digital converter—and replaces or repairs the offending component. We then clear the fault memory and run a full functional test under simulated welding load to confirm the code does not re-appear.
How do I send my COMPUTER WELD 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 COMPUTER WELD 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 COMPUTER WELD 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 COMPUTER WELD 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.
