Introduction

These instructions are intended for experienced operators and those working under the close supervision of skilled

welders. Respect of manufacturer’s instructions and safety prescriptions makes products safe for use in accor-

dance with technical documentation.

IMPORTANT SAFEGUARDS: Read all Instructions

Warning: When using welding and cutting torches, basic safety precautions should always be followed to reduce

the risk of ﬁre and personal injury, including the following:

1. Wear protective attire. Always wear welding goggles to protect eyes from sparks and light rays. Use gloves,

and protective clothing. Watch for sparks in cuffs. Do not wear oily gloves. Do not carry lighters, matches or other

ﬂammable objects in pockets when welding or cutting.

2. Handle Cylinders with care. Chain or otherwise secure cylinders to a permanent ﬁxture. Take care when moving.

To transport cylinders (except when in cylinder carts), remove regulators and replace with valve cap. Never use

any cylinder in other than an upright position.

3. Use “Good Housekeeping” in work area. Keep sparks and ﬂame away from combustibles. Prepare your work

area before welding or cutting.

4. Do not oil or grease equipment. The equipment does not require lubrication. Oil or grease is easily ignited and

burns violently in the presence of oxygen.

5. “Crack” oxygen cylinder valve before installing regulator. Open valve slightly and then close. This will clear valve

of dust or dirt which may be carried to regulator and cause damage or accident. Do not discharge ﬂow of gas at

any person or ﬂammable material.

6. Be sure all connections are tight. Don’t force connections. Never test for leaks with a ﬂame. Use a soapy water

solution and check for bubbles.

7. Purge oxygen and fuel gas passages separately before lighting torch. This will aid in preventing improper mixing

of gases.

8. Use recommended pressure settings. Improper pressures are wasteful. Extreme pressure build up in regulators

is a warning they need repair.

9. Never use oxygen or fuel gas to blow off work, equipment or clothing. Pure oxygen supports combustion and

a spark can ignite oxygen-saturated clothing.

10. Purge system after use. When shutting down, close cylinder valves, then bleed system by emptying both hoses

independently. First, open torch oxygen “OX” needle valve, drain line until pressure is zero, then close oxygen

needle valve. Repeat process with torch fuel “GAS” needle valve.

11. Do not work with damaged or leaking equipment. Use soapy water when checking for leaks. Do not use frayed

or damaged hose. Never use torch as a hammer to knock slag from work.

12. Handle equipment with care. Its continued good service and your safety depend upon it.

13. Keep work area well ventilated. Flammable materials burn violently in an oxygen atmosphere. Flames and

glowing materials (tobacco smoking) must be avoided when using oxygen.

14. When working with acetylene. Never use at pressures over 1.5 bar (Kg/cm

15. Do Not Force connectors and threads. The differences are intentional for the various Gases.

16. Never light a torch with matches or a lighter. Always use a striker

17. Always be aware of others around you when using a torch.

18. Be careful not to let welding hoses come into contact with torch ﬂame sparks from cutting or hot metal.

Set-Up Instructions

Attaching Regulators, Hoses and Torch: (WRENCH NOT INCLUDED)

1. Secure gas cylinders, if used, in upright position.

Note: Check contents of the cylinders before startup to assure an adequate supply for the intended operating cycle.

2. Open cylinder valve (Fig. 1) slightly to blow out dirt, the close. DO NOT discharge ﬂow of gas at any person or

ﬂammable material.

3. Attach regulators (Fig. 2 and 3) and tighten ﬁrmly.

4. Attach hoses to regulators (Fig. 4) and tighten.

Note: The fuel gas hose connections are left hand threads and the oxygen hose connections are right hand threads.

5. Attach fuel gas hose to torch valve (Fig. 5) marked “Gas” (left hand thread).

6. Attach oxygen hose to torch valve marked “OX” (righthand thread).

7. Install correct size tip (Figs. 6 and 7) for metal thickness to be welded or cut. make sure the tip seat is free of

nicks or burrs. Welding tips should be hand-tightened only. Cutting tips should be wrench tightened.

8. Close both valves on torch (Fig. 6) (clockwise) before opening cylinders.

Adjusting Pressure

To identify equal pressure or universal pressure torches, set 2 bar on oxygen supply, disconnect fuel gas hose and

check valve with mixer or cutting attachment on torch. Open all gas valves and check fuel gas inlet. If pressure

is found, equipment is equal pressure type. If suction is noted, equipment is universal pressure type. Reconnect

check valve and hose and purge thoroughly before lighting.

Note: 1. For Equal Pressure Torches (sometimes called “medium pressure”). This equipment requires fuel gas

pressures above 0,1 bar. Positive pressure is used to mix fuel gas with oxygen.

2. For Universal Pressure Torches (sometimes called “low pressure”). This equipment operates with less than 0,1

bar fuel gas pressure. Oxygen, at pressure, creates suction that pulls the fuel gas into the mixer.

1. Be sure both regulator adjusting keys (Fig. 8) are free, by turning counter-clockwise until loose.

2. Slowly open fuel gas cylinder valve (Fig. 9) not over one (1) turn and set regulator key for required operating

pressure. Keep handle or valve wrench on cylinder valve to allow rapid shutdown.

3. To prevent a sudden increase in pressure, slowly open fully the oxygen cylinder valve (Fig. 10). and set regulator

to required operating pressure.

Note: The oxygen cylinder valve should always be wide open when operating.

4. Test connections and regulators for leaks by brushing with a soapy water solution while observing for presence

of any bubbles. If bubbles are observed, tighten ﬁttings and wipe off soap solution. Refer to Regulator Test in the

Maintenance instructions.

Operating Instructions: Lighting Torch for Acetylene and Mapp® Fuel Gas

1. Purge system. Refer to Maintenance Instructions.

2. Open torch fuel “GAS” valve (Fig. 11) approximately one half turn and ignite fuel gas.

3. Keep opening torch fuel “GAS” valve (Fig. 12) until ﬂame stops excessive smoking and leaves the end of tip about

3 mm, then reduce slightly to bring ﬂame back to tip.

4. Open torch oxygen “OX” valve (Fig. 12) until a bright inner cone appears on the ﬂame.

Note: The point at which feathery edges of ﬂame disappear and a sharp inner cone is visible is called the “Neutral

Flame.” ® Airco, Inc.

Lighting Torch for Other Fuel Gases: (Propane, Propylene & Natural Gas)

1. Purge System. Refer to Maintenance Instructions.

2. Open torch fuel “GAS” valve approximately one quarter turn and ignite fuel gas. Close valve slightly if ﬂame

blows off tip.

3. Crack oxygen “OX” valve and open until feathery, secondary cone disappears.

4. Alternately open each valve to bring ﬂame intensity up to the desired point.

Note: A neutral ﬂame has a shortened, sharply deﬁned inner cone, blue in color. Intensity of the color depends on

fuel gas used, but all gases will show lighter blue as oxygen is added past the neutral point.

Shutting Down Equipment

1. First close torch oxygen “OX” valve, then close torch fuel “GAS” valve (Fig. 12). This sequence will prevent ﬂame

from popping out at shut down.

2. Close supply valves for both gases (FIgs. 9 and 10).

3. Bleed off all oxygen at torch “OX” valve, (Fig. 12) then close the valve.

4. Bleed off all fuel gas at torch “GAS” valve, (Fig. 12) then close the valve.

5. All pressure gauges should read 0. Turn both pressure regulator adjusting keys (Fig. 8) counterclockwise until

loose.

Gas Welding and Steel Flame Cutting: Basic Gas Welding Procedures

Gas Welding. Gas welding is a method of joining similar metals by heating the adjacent surfaces to the melting

point with an oxy-acetylene ﬂame, and allowing the two parts to fuse together, with a ﬁller metal being required

on materials 5 mm thick or more. The resulting weld is as strong as the parent metal.
