Condenser & Evaporator Flame Brazing Welding Machine Line
Frequency control and stable working.
Flame auto-ignition, gas leak alarm system and synchronous lock function.
The equipment has air cooling and water cooling, and two cooling methods.
The multi-row welding torch can be electrically lifted and lowered.
The welding machine is a linear structure consisting of frame, drive, transmission line and fire exhaust combustion mechanism. It is suitable for continuous heating of two copper tubes, copper elbows and welding rings, so that the welding rings can melt and evenly fill the gap between the copper tubes and the copper tubes, thus realizing automatic welding of the two devices. Gas, oxygen and nitrogen can be accurately controlled by FLOTRON DF11K / MFC, which ensures stable welding temperature and reliable welding quality.

Features
A 10-meter automated production line for high-volume brazing of copper tubes, elbows, and welding rings in HVAC/R systems. Combines precision gas-flow control (FLOTRON DF11K/MFC), 300–1600mm height adaptability, and 1–4-row processing to create oxidation-free joints using LPG-oxygen flames + nitrogen shielding, achieving ≤0.1mm capillary gaps under 4–6kg/cm² compressed air cooling.
Precision Flame & Atmosphere Management
FLOTRON controllers regulate LPG (1.5kg/cm²), oxygen, and nitrogen flows within ±2% tolerances, while pre-brazing nitrogen purging eliminates oxide formation—critical for copper-aluminum evaporator joints requiring Class A leak-tightness.
Multi-Row Synchronized Processing
Modular torch arrays (64 burners per row, vertical/horizontal fire orientation) with electric lift/lower + manual XYZ-axis fine-tuning enable simultaneous 4-row brazing at 0–3000mm/min conveyor speeds (frequency-controlled), slashing cycle times by 70% vs manual setups.
Fail-Safe Thermal Governance
Dual water/air cooling loops maintain tip temperatures <150°C during continuous operation, integrated with gas-leak sensors, flame-out auto reignition, and explosion-proof housings compliant with ANSI B175.1 safety standards.
Scalable Line Architecture
Expandable 10M stainless steel conveyor (190mm width, 450mm base height) supports jigs for Ø6–25mm tubes. IoT-ready PLC logs brazing metrics (temp/pressure/dwell time) for ASME Section IX weld procedure qualification.
Application
Filter Dryer Line
Mesabi Tube Line
Pancake Coil Line
