My bernzomatic trigger-start torch ignites, but then the flame goes
out within 2 seconds even though gas is obviously still flowing. I
use the torch to sweat copper pipes, but very infrequently. Is there
something I need to clean or maintain? Do I have to buy a new one
every year or so??
What happens if you try to relight it with a flame - like a match?
That wil tell you if the gas flow is sufficient. Maybe the gas is
coming out so fast it blows the flame out somehow. Buying a new one
each year is a stupid way to do things when the spark still works o
your present unit.
My ancient bernzomatic torch came with instructions to temporarily
reverse the orifice so the gas runs counter to the normal flow. This
can free any blockage in the very small diameter holes. Then put it
back to the proper orientation and it should work. However, I don't
know if this fix is applicable to newer models.
If the orifice is clogged, the flame will be smaller, and probably
wouldn't light in the first place. The OP has not said what happens
if he tries to light it using a match, the first step in diagnosing
his problem.. But if the air supply that goes aound the orifice has
dirt or debris in it, like maybe spider webs,, insufficient air will
flow and that will cause flame-out also.
It again likely is partially obstructed somewhere...all I was really
commenting on is the toolset for probing orifii is available and works
much better than the suggested wire for the purpose.
The other suggestions of some compressed air, etc., are still worth doing...
