Frequently asked questions

What are these Light Weight welding tips used for?

They are nozzles for welding mild steel using the oxyacetylene process with lightweight torch equipment. The specs list the application as brazing and heating.

What gas do these tips run on?

They are designed for acetylene, as listed in the specifications.

What sizes are available?

This range covers No. 1, 2, 3, 5, 7, 10, 12, 18 and 25. Choose the size to suit the thickness of the work and the required flame.

Will these fit my torch?

They are the Light Weight (LW) type, intended for lightweight oxyacetylene torch equipment. Check that your torch takes LW-style tips before ordering.

How do I choose the right tip number?

Larger numbers give a bigger flame for heavier work, and smaller numbers suit thinner material. Match the tip to your job and torch capacity.
