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 metal items. Not suitable for welding cast iron or thick cast copper parts. Step 1: Clean the joint thoroughly before welding, removing all dirt and oil. Step 2: Heat the base metal (welding area) to 350400C, then apply the welding wire to the joint. Do not overheat the base metal until it turns red. Note: If the welding wire does not adhere after melting, the base metal has not been heated sufficiently. This torch can reach a maximum temperature of 1300C.
