- 1). Put on your protective goggles and gloves. Remove any potentially flammable materials from the vicinity before you begin.
- 2). Turn both the oxygen regulator knob and the acetylene knob on the cutting torch to neutral.
- 3). Hold the concave side of the striker approximately 1 to 2 inches away from the stream of acetylene and oxygen. Squeeze the metal bands of the striker together to light the flame.
- 4). Turn down the oxygen level until your flame is small, white and almost translucent. At this point, your flame should extend no more than 3 or 4 inches from the end of the torch. This is the preheating flame.
- 5). Pass the preheating flame quickly across the part of the lock you intend to cut. This initiates the oxidation process--making cutting easier--and also provides you with a line to follow when cutting. Do not press the trigger on your cutting torch when preheating the lock.
- 6). Place the preheating flame against the lock. Press the trigger and move the flame slowly across the metal, following the mark made by your preheating flame, until the lock breaks.
