Tips / Nozzles

The Torch tip sizes are numbered from gauge #16 (largest diameter) to a # 33 (smallest diameter) gauge. Tips are sold by package of 12 (dozen) identical sizes. Lower tip numbers mean larger tip orifice diameters.

The tips are made from precision stainless steel capillary tubing.

Within the usual gas pressures ranges the gas flow in the needle and at exit will be in a laminar mode. The tip end does not heat up or glow.

A damaged tip end creates a turbulent gas flow at exit. The tip end might start to glow and finally be destroyed by the flame now sitting direct on the orifice material. Tip must be replaced. Damage to tip ends is usually caused by operating the tip at a too low gas pressure.

To avoid tip damage always:

  • Extinguish flame according instructions
  • Extinguish flame before tip change
  • Extinguish flame before power-down of the Spirflame«
  • Operate always above the 40 mBar minimum gas pressure
  • Use always with the BOOSTER and correct BOOSTER fluid level
  • Do not use tip end as a "tool" for scratching, ..
  • Do not touch tip to a hot surface or do not dip tip in molten solder
