The Orgo Head repair oxy/fuel torch height is how high above the rail surface?

The correct height for the Orgo Head repair oxy/fuel torch above the rail surface is established at 3 inches. This specific height is crucial for ensuring that the flame produced by the torch is effective in reaching optimal temperatures for the thermite process. A height of 3 inches allows for proper heat transfer and uniform molten metal flow during the welding process. If the torch is positioned too high, it may not heat the materials adequately or evenly, leading to incomplete bonding or potential defects in the weld. Conversely, if it is too low, it could cause excessive heat concentration, risking damage to the rail and surrounding materials. Thus, the 3-inch height is a balance that promotes efficiency and safety during the thermite welding operation.
