I am posting again about my LPG torch - it is the same problem I
posted about a short while ago. The problem was that I’d had a
contaminated gas supply which caused the flame to get very weak and
eventually die. I figured out that it must have been a
contamination in the gas supply when I removed the hose from the
bottle and a large quantity of liquid spilled out and had to be
mopped off the floor rather than vaporizing.
First of all, I mentioned in my original post that I now had a new
supply of gas but the gas still didn’t seem to be getting through.
I had figured that the contaminant had caused a blockage in the hose
and/or handpiece. I posted here and on another forum and received
some suggestions on how to flush the blockage out - the suggestions
were varied and some of them didn’t really sound right or safe to
me. In the end I put the problem on the backburner while I took up
several different office work temp jobs and was not in my studio
This brings me to today - I am back in my studio this week and now
back to the problem of my torch. Unfortunately all of the posts
from this forum and the other I posted to that I had saved to my
computer were lost when my computer crashed recently. I just tried
doing a search of the archive but the search engine seemed to not be
working properly - it kept coming up with no results… or perhaps I
was just putting the wrong words in - so, please forgive me for
repetition and not being able to recall properly the suggestions
that people made.
Of the suggestions I had that were of how to flush the hose and
handpiece out I was told by different people to use compressed air,
alcohol, water and water and soap - there may have been others, or
variations on these but I’m sorry - I can’t remember. As far as I
know compressed air is very dirty, however my father said that if I
used a filter and blew compressed air through it would be fine. I
think compressed air would move hard blockages fairly well, but what
if it is some kind of greasy buildup? Would it still do a good job?
Water sounds a little strange to me - I had thought that gas and
water could be explosive - or am I thinking of something else?
Alcohol sounded more strange than water as if any residue remained
it would be a fire hazard - or would it not? I think it was
suggested to clean with soap and water and then follow with alcohol
to make sure that no water droplets remained. In any case -
mightn’t alcohol dry out the hose and make it more prone to
I’d had a thought - back in high school when I played clarinet - my
teacher taught me to clean it by taking a soft cloth and attaching a
length of string longer than the clarinet with a weight on the end
to it, then dropping the weight down the clarinet and grabbing it at
the other end to pull the cloth through. Maybe a similar method
with a much smaller cloth could be used for my torch? However, what
if remnants of the cloth became attached to the inside of the hose?
This could cause more blockages - right? If not blockages, would it
become a safety hazard?
I have emailed my supplier asking for advice who (very predictably)
told me that the problem couldn’t be fixed and that I’d need to
purchase a new torch.
A bit of discussion on the safety and effectiveness of various
methods of flushing the hose and handpiece out would be very useful
to me. I am one of those people who took YEARS to get comfortable
with using a torch as it was so difficult for me to shake the
feeling that it was dangerous… and now, I am nervous about
fiddling with my torch in case I really do make it dangerous.
Thanks everyone for your continual help, support and understanding!
