When the temperature is below 30¡ãC(86¡ãF), a stable flame could be obtained easily by preheating the cutting tip when lighting the torch for the first time.
Way of cutting tip preheating:
Reduce the length of the flame core so that the blue flame core burns in the cutting tip for 3-5minutes in a warm environment and about 5-8minutes in a cold environment. The flame should be blue during the preheating. If it turns red, increase the oxygen supply or reduce the gasoline supply.
