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 with universal copper-aluminum flux-cored welding wire (not tin welding wire) for welding and repairing copper, aluminum, iron, stainless steel, and other common household metals. Not suitable for welding cast iron, cast copper, or other hard and thick castings. Step 1: Clean the welding joint thoroughly to remove dirt and oil before starting. 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 torch can reach a maximum temperature of 1300°C.
