Synchronics Electronics repairs AIRCO welding power sources, cutting control modules, and thermal management systems across all industrial categories. Our 180+ engineers have extensive field experience with AIRCO legacy equipment still operating in Indian steel mills, shipyards, and fabrication shops. We handle component-level diagnostics, capacitor replacement, thyristor stack repair, and logic board restoration — keeping aging AIRCO assets operational and cost-effective.
Expert AIRCO welding equipment and thermal system repairs across India since 1994.
AIRCO Product Lines We Repair
Our engineers are trained on the full AIRCO product range. Below are the major product families we service.
AIRCO AC/DC Welding Power Sources
Heavy-duty transformer-based and inverter welding units for stick, MIG, and TIG applications. Common failures include primary transformer core saturation, secondary rectifier stack breakdown, and output regulation circuit drift — all field-repairable at component level.
AIRCO Plasma and Oxy-Fuel Cutting Systems
Precision cutting control modules with arc initiation and gas regulation circuits. Typical faults: high-frequency oscillator failure, torch cable insulation breakdown, solenoid coil burnout, and CNC interface board damage from moisture ingress.
AIRCO Gas Regulation and Distribution Control
Flow control boards, pressure transducers, and solenoid-based valve modules for shielding gas and coolant delivery. Failures often stem from internal regulator diaphragm rupture, pressure sensor drift, or solenoid windings corroded by humid Indian industrial environments.
AIRCO Legacy Thyristor Control Boards
Vintage phase-control and trigger boards used in older AIRCO welding equipment. Prone to thyristor junction degradation, gate drive circuit failure, and snubber capacitor leakage after 15-20 years of industrial duty in hot Indian fabrication shops.
AIRCO Thermal Spray Gun Controllers
Arc and flame spray system controllers managing wire feed, gas flow, and arc voltage. Repair needs include arc voltage feedback instability, motor drive failures, and relay chatter due to vibration and thermal cycling in continuous operation.
Why Choose Synchronics for AIRCO Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on AIRCO equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AIRCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AIRCO equipment arriving at our workshop.
- ✓AIRCO welding output unstable or drifts — Voltage regulator op-amp degradation or feedback potentiometer contact corrosion in humid Indian factories. Secondary rectifier diodes showing soft failure characteristics.
- ✓AIRCO torch ignition fails or arcs erratically — High-frequency oscillator coupling capacitor dried out or cracked; torch cable insulation degraded allowing leakage current. Trigger transformer saturation from repeated moisture exposure.
- ✓AIRCO gas solenoid remains open or won't close — Coil winding burned due to continuous energization or voltage spike; plunger seized by mineral deposits from impure shielding gas; driver transistor failed in control board.
- ✓AIRCO control board shows no display or frozen display — Microcontroller memory corruption from power surges; LCD backlight inverter capacitor leakage; RS-232 interface isolation optocoupler failure in networked installations.
- ✓AIRCO thyristor stack shorts or firing angle won't adjust — Gate oxide degradation under thermal stress; snubber network component failure (capacitor or resistor open); trigger pulse transformer core saturation from age and heat exposure.
- ✓AIRCO primary transformer overheats excessively — Core lamination corrosion and iron loss increase; winding insulation breakdown allowing turn-to-turn shorts; cooling fan motor bearing wear reducing airflow. Moisture and dust accumulation common in Indian steel mills.

Frequently Asked Questions — AIRCO Repairs
Do you repair AIRCO equipment anywhere in India?+
Yes. Synchronics repairs all AIRCO welding, cutting, and thermal spray equipment across India. We offer door-to-door pickup and delivery from major cities: Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. All repairs performed at our Vadodara, Gujarat facility with 180+ specialized engineers. Turnaround is typically 7-14 days depending on fault complexity.
What is the typical repair cost for an AIRCO welding power source?+
AIRCO repair costs range from Rs 3,000 (simple board-level component replacement) to Rs 35,000 (transformer rewinding or thyristor stack rebuild). We provide free diagnostic assessment and written quotation within 48 hours of receipt. No repair is undertaken without your approval. Many customers find repair 40-50% cheaper than new equipment — especially valuable for legacy AIRCO units still performing reliably.
Do you repair older AIRCO thyristor-based welding sets or only modern inverter units?+
We repair both legacy thyristor and phase-control AIRCO sets as well as modern IGBT inverter models. Many Indian fabrication shops still operate 1980s-1990s AIRCO equipment due to robust build quality and spare parts availability. Our engineers have deep expertise in vintage phase-control circuits, transformer design, and gate drive electronics. We stock hard-to-find thyristors and custom-rewind transformers to restore these workhorse machines.
Can you fix AIRCO cutting system torch ignition or plasma flow problems?+
Absolutely. AIRCO plasma and oxy-fuel cutting systems are common in Indian shipyards and structural steel shops. We repair torch ignition circuits, pressure control boards, solenoid drivers, and gas distribution modules. If your AIRCO cutter has weak arc strike, erratic flow, or display errors, send it to Synchronics. We test all cutting parameters under load and provide detailed repair reports.
Do you offer warranty on AIRCO repairs and what if the same fault returns?+
All Synchronics repairs include a 12-month comprehensive warranty against manufacturing defects. If the same fault recurs within warranty period, we repair free of charge (excluding new parts). We also provide optional extended service plans for critical production equipment. Our quality assurance includes 100-hour burn-in testing for welding units and full parameter validation before dispatch.
How do I send my AIRCO 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 AIRCO 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 AIRCO 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 AIRCO 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.
