ich would leak out or be forced out if the cylinder was laid in a flat position. Also, welding guns and other cables should not be hung on or near cylinders. A gun could cause an arc against the
cylinder wall or valve assembly, possibly resulting in a weakened cylinder or even a rupture.
Q: How can I tell if my regulator is faulty?
A: The following symptoms indicate a faulty regulator:
z
s - if gas leaks externally. Excessive сreep - if delivery pressure continues to rise with the downstream valve closed. Faulty gauge - if gauge pointer does not move off the stop pin when
pressurized, nor returns to the stop pin after pressure release. Do not attempt to repair a faulty regulator. It should be sent to your designated repair center, where special techniques and tools are used by trained personnel.
Q: How should an operator dress for optimum safety?
A: Gloves and clothing should be flame-resistant. Clothing made from a dark-colored, tightly woven material is best suited for welding. Gauntlet-type leather gloves should be worn to protect the hands and wrists. Shirt collars and shirt cuffs should be buttoned, and open front pockets are not advisable as they may catch sparks. Also, operators should never store matches or lighters in their pockets. Pants cuffs are not recommended, as they will also catch sparks. Tennis shoes do not qualify as adequate foot protection. Hightop leather shoes or boots are absolutely necessary.
Preparation to the total test.
