What WTL does

WTL (Shanghai WTL Welding Equipment Manufacture Co., Ltd. / 上海威特力焊接设备制造股份有限公司), founded in 1993 in Shanghai, is a Chinese manufacturer of inverter welding power sources and welding/cutting equipment. Its core technology stack is built around IGBT-based PWM inverter power electronics, augmented by proprietary features including PFC (power factor 0.99, 95V–275V input range), soft switching, a patented radiator thermal-management system, and digital microcomputer waveform control recognized by the Shanghai Science and Technology Commission. The product portfolio spans MMA/stick, TIG, MIG/MAG, plasma cutting, and specialty heavy-duty welders (ZX7, WS, MZ, NB, MAGIC, MAGIC CUT, FNL, WSM, WSME series), with select models offering 4G IoT connectivity for real-time data upload, parameter enforcement, and usage analytics. WTL also operates an ODM model, designing and producing customized welding solutions with 8+ years of custom project history, and provides after-sales service through a nationwide network.

The company serves vertically regulated end-markets where welding quality, certification, and reliability are decisive: nuclear power (where it is the sole authorized supplier of all TIG models to China's nuclear power companies and a 2025 CNNC qualified supplier), aerospace, shipbuilding, transportation (heavy trucks, rail, autos, recreational vehicles, ships), petrochemical/chemical, boilers and pressure vessels, and general manufacturing and maintenance/repair. WTL is listed on China's New Third Board (NEEQ) under stock code 873061 since November 2018, operates three wholly-owned subsidiaries (Nanjing WTL Welding Equipment, Tianjin Northern WTL Trading, Shanghai WTL Automation), and runs a 15-branch / 30+ agent domestic distribution network plus direct export sales into Europe, the United States, Australia, and Brazil. Revenue is generated primarily through hardware sales (inverter welding machines and plasma cutters) supplemented by ODM custom design work and after-sales technical service. The company completed a full factory relocation in December 2024 to a 14,283 sqm automated facility in Songjiang, Shanghai, doubling prior production footprint and supporting stated annual capacity of 250,000–300,000 welding machines.
