Hwashi Launches High-Speed Condenser Welding Machine Series for Refrigerator and HVAC Coil Production

Hwashi Expands Its Condenser Welding Machine Range for Refrigerator and HVAC Coil Production

Guangdong Hwashi Technology Inc. (“HWASHI”), a resistance welding equipment and welding robot manufacturer established in 2001, is presenting its full range of condenser welding machines and wire tube condenser production lines to refrigerator, HVAC, and heat exchanger manufacturers worldwide. The range now covers more than fifty machine configurations, from compact single-cell welders for small batch production to twelve-head gantry systems built for continuous high volume output.

With roughly 70–80% of its output exported and more than 5,000 customers served, HWASHI has built its condenser welding program around the specific bottlenecks that coil factories face: leak-free joints, repeatable positioning, and cycle time that keeps pace with upstream tube bending and wire straightening equipment.

The Whole Condenser Line, Not Just a Single Machine

Condenser welding is rarely a standalone step. A finished refrigerator or HVAC condenser requires several matched stations, and mismatched equipment is one of the most common sources of scrap and idle time. HWASHI supplies the complete sequence:

• Wire straightening and cutting machine — high speed straightening with touch screen control
• Bundy tube straightening and cutting machine — copper, aluminium, and coated Bundy tube
• CNC Bundy tube bending machine — PLC controlled, 3–8 mm tube capacity, 380 V / 50 Hz
• Condenser wire mesh welding machine — six, eight, ten, and twelve-head configurations
• Condenser bending machine — integrated welding and bending options
• Tube end expanding and shrinking machines — 4.76 mm, 6.35 mm, and 8.00 mm tube diameters

Flagship Models and Key Specifications

Why Weld Quality Holds: MF DC Power and Servo Positioning

On the newer high-speed platforms, medium-frequency DC (MFDC) transformers replace conventional AC welding transformers. The DC output produces a tighter current waveform, which reduces spatter on thin low carbon steel wire and gives a more consistent nugget diameter from the first weld of a shift to the last. Combined with servo-driven electrode positioning and a two-station feeding fixture system, the machine keeps welding while the operator loads the next set of frames — the practical basis of the 2.5 second per mesh cycle on the WL-HS-300K.

Customization, Lead Time, and Commercial Terms

Effective welding width is the parameter most often customized, with 600–1000 mm offered as standard on the compact and high speed platforms and wider gantries available on request. Minimum order quantity is one set, supply ability runs at 40–50 sets per month depending on model, and delivery is typically 25–45 working days after deposit. Machines ship in export-grade plywood cases with anti-rust film, and payment terms are L/C or T/T.

Service Commitment

• 12-month warranty on all condenser welding machines
• ISO 9001 quality system, CCC and CE certification on applicable models
• 24-hour technical support by email, with remote commissioning assistance
• 100% test run before shipment; typical service life of 8–10 years
