1-10. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS (CONT).
1.
ARGON HOSE REEL. Holds 50 feet of 3/8 in. ID hose, used to supply MIG welder with argon gas.
2.
OXYGEN-PROPYLENE HOSE REEL. Holds 50 feet of 1/4 in. ID twin hoses, used to supply a welding
torch or a cutting torch with oxygen and propylene gas.
3.
PROPYLENE GAS REGULATOR. The propylene regulator is a two stage regulator. The high pressure
gage, the inlet side, shows the pressure from the cylinder and is graduated from 0 to 400 psi. The low
pressure gage, the outlet side, shows the working pressure and is graduated from 0 to 30 psi.
4.
OXYGEN GAS REGULATOR. The oxygen regulator is a two stage regulator. The high pressure gage,
the inlet side, shows the pressure from the cylinder and is graduated from 0 to 4000 psi. The low pressure
gage, the outlet side, shows the working pressure and is graduated from 0 to 200 psi.
5.
ARGON GAS REGULATOR. The low pressure flowmeter, the outlet side, provides 0–4000 psi and it
provides better gas flow control for working pressure than a regulator. The flowmeter is calibrated in
cubic feet per hour (cfh). The correct flow of argon to the torch is set by turning the adjusting screw on
the regulator. The rate of flow depends on the kind and thickness of the metal to be welded.
