What Did I Buy?

[hddennis]

Just bought this neat little torch off eBay because I couldn't resist it. It's a Marquette Aerojet GW4-1-9 with a GW4 5-1 cutting head and many attachments. I'm no welder just want to use it in my restoration work on my 1917 Maxwell. Have heard this called an aircraft or radiator torch but don't know why nor do I have a clue what all these attachments are for. Anyone have any literature or information on this?

Thanks,
Howard Dennis

You have a bunch of welding tips, and rosebud tip in addition to the cutter.

The braising tips were often used to weld the seams of radiators.
