Hi All - OK - here’s the real scoop on how to light your LT, or any
other mixed fuel arrangement: GOGO, as someone else said (sorry
Karen). Gas On Gas Off - IE., when lighting the torch, gas on
first, and when extinguishing the torch, gas off first.
Here’s the link to the LT site’s instructions for torch lighting
which gives those instructions - http://www.lacywest.com/t_little.htm
and here’s a bunch of other sites, all saying the same thing…
Purdue U -
- Slightly open the acetylene valve on the torch and then use the
striker to ignite the acetylene. … 19. When you are finished
welding, the acetylene valve at the torch should be closed first, and
then the oxygen valve should be closed secondly.
Eastern Michigan College of Technology-
Open the acetylene torch valve partially and light the torch.
Add oxygen to produce a neutral flame…
Turn off acetylene torch valve first to extinguish the flame and
then turn of the oxygen torch valve.
