MICROFLAME TORCH

also known as a Hand Torch, Brazing Torch, Hand Welder, Miniature Welder

The prop used in the movie appears to be a un-altered Microflame Torch.

As seen in Star Wars: A New Hope 1977

  • Used to weld the Restraining Bolt onto R2-D2 by a Jawa just before R2 is sucked up into the Sandcrawler.

  • Used by Luke Skywalker in Obi-Wans hutt when making repairs on C3-P0- after the Tusken Raider fiasco

  • Micro gas cylinder used as part of Han Solos belt

This web page is a culmination of my research regarding the screen-used hand torch in Star Wars: A New Hope. Be advised the content here-in is based on my own research and is not guaranteed to be 100% accurate.

This research adventure started because I 3-D printed a torch I found online for my Jawa prop/costume and wanted to make accurate text for it because I didn’t like the way it looked without it. I really didn’t think it looked like a Model-B torch as I saw identified in other places so identifying the model led me into a rabbit-hole and I eventually just did as much research as I could on it. Don’t judge me lol

MODEL IDENTIFICATION COMPARISON

Gold metal Microflame Torch. Without “Model B” markings, narrows it down to 2 models. The timeline is also off for Model B torches from my research, as it’s first appearance is in the 1983 RadioShack catalog.
