Need parts for victor 272654 oxy reg

sounds like diaphram is faulty ?

take it to the nearest weld shop, its defective, gages, do one thing, keep pressure where you put it, there is a spring inside and it can get weak by leaving it turned in,
please, take it to a shop, before it fails.

bad o2 reg.

The only part of the gauge that adjust is the tee handle in the middle. the gauge on the left tells you the line pressure to the torch, the gauge on the right tells how much oxygen is in the bottle, usually on a K bottle it is 1800 to 2000 lbs. if you turn the tee handle and the left gauge that tells line pressure does not respond you probably have a bad diaphragm in the gauge. Seek qualified repair man. Thanks

send it in for repair at any welding supply, most of them will ck' it out for free before they repair it, probably is grain of dirt / sand will cause that effect.

Sounds true. The oxygen sensor regulates the fuel air (oxygen) mix for optimum performance with the least amount of fuel. If the oxy sensor malfunctions you'll get the incorrect fuel/air mix and waste fuel. Some vehicles see a 10% increase in fuel use with a bad O2 sensor.

replace it the and check your regulator valve your leaking, may be a seal is out in side your gage. i would replace it fri-st, if that doen't work have your regulator check. good luck

Diaphragm needs replacing. Take it to the shop...this needs to be done correctly.

call ESAB they bought Victor 843-664-4405

One gage is fixed for tank volume the other is variable for you to set for process. if the variable gage dose not work you may have a bad diofram. You could purchase replacement repair parts at your welding supply store.
