Model-O Type No.1/2/3/5 Welding Tip Range

Frequently asked questions

What are Model-O welding tips for?

They are for very fine welding and brazing, including fusion welding of thin gauge sheet metal up to 1.5mm (1/16in) and delicate lead welding.

What gas do these tips use?

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

What sizes can I get?

The Model-O range covers No. 1, 2, 3 and 5. Pick the size to suit the thickness of your material.

Why choose a Model-O tip?

It produces a small, focused flame that is easy to handle, keeping the heat-affected zone to a minimum on precise, heat-sensitive work.

Which tip number should I choose?

Smaller numbers give a finer flame for thinner or more delicate work, while larger numbers suit slightly heavier jobs. Match the tip to the task.
