Smith Equipment Heavy Duty - Oxygen. Acetylene Heating Tip. Model # ST605. Heating tips used in welding handles. Smith's multi-flame and single flame heating tips are designed to provide large volumes of heat for applications such as: heat treating, bending, straightening, pre-heating, brazing, shrinking, forming and many others. Smaller sizes are often used for braze welding or for applying hard facing metal to large areas. Heating tips provide significant cost savings in many applications. By providing great amounts of quick, concentrated heat, heating tips do the job faster and cut labor time to a minimum. For proper performance, use the recommended pressures for each tip and with an adequate gas supply. Manifolding of cylinders is essential for safe and efficient operation of large size heating tips. Warning: MANIFOLDING CYLINDERS: When required flows (cubic feet per hour- SCFH) exceed the recommended withdrawal rate from one cylinder then additional cylinders must be manifolded to provide safe and efficient operation. Acetylene must not be withdrawn at more than 1/7 of the cylinder capacity )50 SCFH for a 350 cubic foot cylinder. Consult you gas supplier for manifolding instructions for the gases and cylinders supplied to you. Refer to Technical Data on smith Equipment website. Used In: Torch handles: WH200, SW1B and SW1A.
