The flame torch is convenient for use in 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 cast iron, cast copper, or other hard and thick castings. Step 1: Clean the welding joint thoroughly to remove dirt and oil. Step 2: Heat the base metal (welding parts) to 350400C, then apply the welding wire at the joint. Do not overheat the base metal until it turns red or melt the wire without proper base heating. Note: If the welding wire does not adhere after melting, the base metal has not reached sufficient temperature. The torch can reach a maximum temperature of 1300C.
