The flame torch is convenient to use and suitable for metal welding, pipe thawing, outdoor barbecue, cake baking, air conditioner and refrigerator copper pipe processing, singeing, and household maintenance. Welding Instructions: Use universal copper-aluminum flux-cored welding wire (not tin welding wire) for welding and repairing copper, aluminum, iron, stainless steel, and other common household metal products. Not suitable for welding cast iron, cast copper, or other hard and thick castings. Step 1: Clean the welding joint thoroughly before starting. Ensure it is free from dirt and oil. Step 2: Heat the base metal (welding parts) to 350–400°C, then place the welding wire at the joint for welding. Avoid overheating the base metal to the point of redness. Note: If the welding wire does not adhere after melting, the base metal has not been heated sufficiently. The maximum temperature of this welding torch reaches 1300°C.
