Following the closure of TheWeldersWarehouse.com and TheWeldersWarehouse.co.uk the Pro-Jet nozzle is not currently available. We have an alternative to the Pro-Jet Model O tip which has been designed to work with propane but gives you a single flame point. A direct fit into the Model O torch neck.

Propane Model "O" Lead Welding Tips

Our Model O Propane tips have been sized to match the numbering of the acetylene version so if you normally use a #2 acetylene, buy a #2 propane.

The roofers and lead burners torch of choice is the Model O. For all Model O torches our tips will fit. The propane tips have been designed specifically by Noz-Alls with the correctly sized flame retention cup to ensure that the flame doesn't 'pop off' the end of the nozzle tip. These Model "O" tips have a minute and stable flame which is easy to work with.

For other applications and as with any of the smaller torches there is an overlap in nozzle sizes. As such, when you find that the size 1 Light Weight or Type 5 swaged welding nozzle for the FN or the Type 3 / Type 5 torches are too big then switching to the Model O torch may well be just what you need.
A size 1 standard welding nozzle is between a size 3 and a size 4 Model O tip.
