Last fall I exchanged an acetylene tank for a refilled one. The
flame burned orange and didn’t seem to be as hot as the blue flame in
Finally got around to exchanging this tank in April 2016. It also
burned orange, cooler flame.
My closest Goss torch supplier worked patiently with me over the
phone to double check every component of my Goss torch equipment -
even sent me replacement filters and one replacement orifice for my
most-used torch tip. All seems to be in order with my equipment and
the torch flame was still orange.
I took this tank back to my local welding shop yesterday. The shop
tested my tank with their torch (orange flame). Then the shop tested
every single available refilled tank in their shop with their torch
equipment. All tanks burned orange.
My local shop then tested two of their own older tanks, which they
keep on hand to make minor repairs for customers. Both of these tanks
burned with a blue flame.
My question to the Ganoksin team - has some standard for acetylene
gas changed? Do you think the shop’s gas supplier might have changed
some aspect of generating their gas, or might inadvertently have
introduced a contaminant into their current gas supply?
Thanks in advance,
