MT603 - Miller Smith MT603 Medium Duty 6-Flame Acetylene Heating Tip

Miller Smith MT603 Medium Duty Acetylene Heating Tip

The Miller Smith MT603 is a premium medium-duty heating tip designed for professional oxy-acetylene applications requiring substantial heat input. Part of the renowned MT Series, this multi-flame tip is engineered to deliver a high volume of concentrated heat, making it an essential component for industrial metalworking, fabrication, and maintenance operations. The tip features a six-flame configuration that produces an average heat output of 40,125 BTU per hour, significantly reducing the time required to reach critical temperatures compared to single-flame welding tips.

Manufactured from solid copper, the MT603 is built to withstand the rigorous thermal cycles associated with heavy heating tasks. Copper's superior thermal conductivity aids in keeping the tip cool during operation, prolonging the service life of the equipment and maintaining consistent flame characteristics. This specific model is designed for use with Acetylene or Hydrogen fuel gases and is not suitable for alternate fuels like Propane or Propylene. It is precisely machined with a drill size of 64 to ensure optimal gas flow and flame stability.

Compatibility is a key feature of the MT603. It is designed to fit Smith Equipment's popular medium-duty torch handles, including the WH100, MW5A, and CW5A models. With an overall length of 10 inches, it provides the operator with adequate reach and distance from the radiant heat of the workpiece. Safety is paramount when using high-output heating tips; operators must ensure that their acetylene cylinder capacity is sufficient to support the withdrawal rate (following the 1/7th rule) and that high-flow flashback arrestors are installed to prevent flow restrictions and ensure safe operation.

This tip is an excellent choice for a variety of thermal processes. Whether the task involves pre-heating weldments to prevent cracking, bending steel bars, straightening distorted structural members, or applying hard-facing materials, the MT603 delivers the reliable performance professionals expect from Miller and Smith Equipment products.
