2. Safety Precautions—Read Before Using

Do not use this equipment unless

you are trained in its proper use or

are under competent supervision.

Follow the procedures described in

this booklet every time you use the

equipment. Failure to follow these

instructions may cause fire, explo-

sion, asphyxiation, property dam-

age,

personal

equipment must be used in accord-

ance with all Federal, State, and lo-

cal regulations as well as DOT

(Department of Transportation) and

CGA (Compressed Gas Associa-

tion) regulations. Contact your gas

supplier for more information on

the proper use of compressed

gases.

3. Introduction

The Gasaver is an accessory for inside bench production and assembly line gas brazing and welding applications. It is designed for use in the

oxygen and fuel gas supply lines for hand welding torches. The pilot light (Item 15) on Models WDW100, WDW101, and WDW104 is supplied

with fuel through an internal passage connecting it to the main fuel inlet. The Model WDW103 pilot light requires a separate fuel connection to a

high-pressure fuel source (minimum pressure of 4 PSI is required for adequate flow to sustain pilot light). A 3/16 in. (4.76 mm) ID fuel hose

should be used to connect the pilot light adapter (Item 17) to an appropriate fuel source. If using hydrogen as the torch fuel, propane or natural

gas is recommended for the pilot light. The Gasaver shut off valves can be individually adjusted by their seat adjustment screws and lock nuts

(Item 10 and 11). See Section 7 for parts identification that will aid in installing/using this equipment.

listed in Section 3.

Use an approved oil-free leak de-

tection fluid to locate possible

leaks. PTFE tape is an acceptable

pipe thread sealant. If other sealing

materials are preferred, those ma-

terials must be compatible with the

gas that is being used in the

system.
