WELDERNEED Factory Tour — PCB assembly, welding machine production, quality testing, and container loading
Product Showroom
Our on-site showroom displays the complete WELDERNEED product range — MMA, MIG, TIG welders and plasma cutters, ready for distributor inspection and OEM customization review.
Our Manufacturing Process
PCB Design & SMT Assembly
Our in-house engineers design PCBs optimized for welding performance. Surface Mount Technology (SMT) lines ensure precise component placement and consistent soldering quality. Every board is optically inspected before moving to assembly.
SMT workshop corridor — ESD-safe PCB storage and component staging area
Component Assembly
Trained technicians assemble IGBT modules, transformers, capacitors, and control boards into rugged housings. Each connection is torque-checked and strain-relieved to withstand vibration and transport.
Assembly line — technicians building welding machines at dedicated workstations
100% Aging Test
Every single machine undergoes a minimum 4-hour aging test at full rated current. We test at 40°C ambient to ensure real-world duty cycle performance. No machine leaves the factory without passing this test.
Quality Inspection & Packing
Final inspection checks output current, insulation resistance, and all safety features. Machines are packed with foam protection, accessories, and user manuals. Custom OEM packaging available.
Testing station — final quality checks before packaging and shipping
Warehouse & Container Loading
Finished products are stored in our warehouse and loaded into containers at Qingdao Port. We handle all export documentation, customs clearance, and shipping arrangements.

Quality Control
Incoming Inspection
All components (IGBT modules, transformers, capacitors, PCBs) inspected before entering production. Reject rate below 0.5%.
Raw material warehouse — organized component storage with zone-based inventory management
Assembly Inspection
Torque checks on all electrical connections. Visual inspection of soldering quality. Component placement verification at each assembly stage.
Load Testing
Every machine tested at rated current under load. Output current, voltage, and arc stability verified against specifications.
Burn-In Testing
Minimum 4-hour continuous operation at full rated current in 40°C ambient. No machine leaves without passing this test.
Final Inspection
Complete function test, insulation resistance check, safety features verification, and cosmetic inspection before packaging.
R&D and Testing Laboratory
Our dedicated R&D lab drives continuous innovation in welding technology. From component-level failure analysis to full-machine performance validation, our engineers test every design iteration under real-world load conditions — ensuring reliability before a single unit reaches the production line.

Factory FAQ
We are a factory (manufacturer), not a trading company. Qingdao Welderneed Machinery Co., Ltd. has been manufacturing welding machines since 2005 in Qingdao, China. You buy direct from the factory.
Yes. We welcome distributors and partners to visit our factory in Qingdao. Contact us to schedule a tour, or request a video call to see the factory remotely.
Yes. We provide full OEM service including custom branding, colors, packaging, and manuals. OEM MOQ is 50 units per model.
We use a 6-Sigma quality control system with 5 inspection stages: incoming inspection, assembly inspection, load testing, burn-in testing (4+ hours at full current), and final inspection. Every unit is tested — not batch sampling.
