7.

Read and understand all instructions and safety precautions as outlined in
the manufacturer’s manual for the material you will weld or cut.

6.

Always keep the Welding Hoses (7, 8) away from moving parts on the tool.
Examine the Welding Hoses for cuts, burns, or worn areas before each use. If any
damaged areas are found, replace the Welding Hoses immediately.

8.

Proper cylinder care. Secure cylinders to a cart, wall, or post, to prevent them
from falling. All cylinders should be used and stored in an upright position.
Never drop or strike a cylinder. Do not use cylinders that have been dented.
Cylinder caps should be used when moving or storing cylinders. Empty cylinders
should be kept in specified areas and clearly marked “empty”.

9.

Never use oil or grease on any inlet connector, outlet connector, or cylin-
der valves.

10.

Always use reverse-flow check valves (not included) on the torch and
regulator.
This greatly reduces the possibility of mixing gases in the regulator or
hose.

11.

Working pressure on the Acetylene Regulator should NEVER be set above
6 PSI.

12.

For the Cutting Attachment, inspect the tapered seating surfaces on the
Tip and in the Torch Head.
Have a qualified technician resurface the seat area
if it has dents, burrs, or is burned. A poor seating surface may result in

backfire

or

flashback

.

13.

Backfire and flashback. When the flame goes out with a loud “pop”, it is called
a

backfire

. Backfire can be caused by (1) operating the Torch at lower pressures

than required for the Tip used, (2) touching the Tip against the workpiece, (3)
overheating the Tip, or (4) an obstruction in the Tip. If backfire occurs, shut off
the Torch Handle Valves (oxygen first) and after remedying the cause, relight the
Torch. A

flashback

is a condition that results when the flame flashes back into

the Torch and burns inside with a shrill hissing or squealing noise. If flashback
occurs, close the Torch Handle Valves (oxygen first), IMMEDIATELY. Flashback
generally indicates a problem that should be repaired. A clogged Tip, improper
functioning of the Valves, or incorrect acetylene/oxygen pressure could lead to
flashback. Make sure to find the cause before relighting the Torch.

SPECIFIC SAFETY RULES

1. Maintain a safe working environment. Keep the work area well lit. Make sure

there is adequate surrounding workspace. Always keep the work area free of

obstructions, grease, oil, trash, and other debris. Do not use the Welder in areas

near flammable chemicals, dusts, and vapors.

2. Maintain labels and nameplates on the Welder. These carry important

information. If unreadable or missing, contact HarborFreightTools for a

replacement.

3. Prevent eye injury and burns. Wearing and using personal safety clothing and

safety devices reduce the risk of injury. Wear ANSI approved safety impact

eyeglasses with a welding helmut featuring at least a number 10 shade lens

rating. Leather leggings, rubber soled, fire resistant shoes or boots should be

worn when using this Welder. Do not wear pants with cuffs, shirts with open

pockets, or any clothing that can catch and hold molten metal or sparks. Keep

clothing free of grease, oil, solvents, or any other flammable substances. Wear

dry, insulating gloves and protective clothing. Wear an approved head covering to

protect head and neck. Use aprons, cape, sleeves and shoulder covers, and bibs

designed and approved for welding procedures. When welding overhead or in

confined spaces, wear flame resistant ear plugs or ear muffs to keep sparks out of

ears.

4. Avoid overexposure to fumes and gases. Always keep your head out of the

fumes. Do not breathe the fumes. Use enough ventilation or exhaust, or both, to

keep fumes and gases from your breathing zone and general area. Where

ventilation is questionable, have a qualified technician take an air sampling to

determine the need for corrective measures. Use mechanical ventilation to

improve air quality. If engineering controls are not feasible, use an approved

respirator. Work in a confined area only if it is well ventilated, or while wearing an

air-supplied respirator. Follow OSHA guidelines for Permissible Exposure Limits

(PEL’s) for various fumes and gases. Follow the American Conference of

Governmental Industrial Hygienists recommendations for Threshold Limit Values

(TLV’s) for fumes and gases. Have a recognized specialist in Industrial Hygiene

or Environmental Services check the operation and air quality and make

recommendations for the specific welding situation.

5. Do not perform welding or cutting operations near chlorinated hydrocarbon

vapors produced by degreasing or painting. The heat generated by arc rays

can react to form phosgene, a highly toxic gas.

6. Irritation of the eyes, nose, and throat are symptoms of inadequate

ventilation. Take immediate steps to improve ventilation. Do not continue

operations if symptoms persist.

SKU 91149 For technical questions, please call 1-800-444-3353. PAGE 6


7. When welding or cutting in small areas, the operator should be externally

accompanied by another person (standing near the enclosed work area) to

observe accident prevention procedures.

8. When welding or cutting, be aware that high frequency radiation may be

produced which can interfere with radio navigation, safety devices,

computers, and communications equipment. Before operating, have a

qualified technician check out that possibility.

9. Keep high frequency source doors and panels tightly shut. Keep spark

gaps at the correct settings. Use proper grounding and shielding to minimize the

possibility of interference. Keep all cables close together and close to the

ground. Locate the welding or cutting operation as far as possible from sensitive

electronic equipment, or have the electronic equipment shut down temporarily.

10. Prevent accidental fires. Remove any combustible material from the work

area. When possible, move the work to a location well away from combustible

materials. If relocation is not possible, protect the combustibles with a cover

made of fire resistant material. Remove or make safe all combustible materials

for a radius of 35 feet (10 meters) around the work area. Use a fire resistant

material to cover or block all open doorways, windows, cracks, and other

openings. Enclose the work area with portable fire resistant screens. Protect

combustible walls, ceilings, floors, etc., from sparks and heat with fire resistant

covers. If working on a metal wall, floor, ceiling, etc., prevent ignition of

combustibles on the other side by moving the combustibles to a safe location. If

relocation of the combustibles is not possible, designate someone to serve as a

fire watch, equipped with a fire extinguisher, during the welding process and at

least one half hour after the welding is completed. Do not place the torch on any

material other than bare concrete until the torch is completely cooled. Do not

weld on materials having a combustible coating or combustible internal structure

such as walls or ceilings, without an approved method for eliminating the hazard.

Do not dispose of hot slag in containers holding combustible materials. Keep a

fire extinguisher nearby, and know how to use it. After welding, make a thorough

examination for evidence of fire. Be aware that easily visible smoke or flame

may not be present for some time after the fire has started. Do not weld in

atmospheres containing dangerously reactive or flammable gasses, vapors,

liquids, and dust. Provide adequate ventilation in work areas to prevent

accumulation of flammable gases, vapors, or dust. Do not apply heat to a

container that has held an unknown substance or a combustible material whose

contents, when heated, can produce flammable or explosive vapors. Clean and

purge containers before applying heat. Vent closed containers, including

castings, before preheating or welding.

11. Read and understand all instructions and safety precautions as outlined in

the manufacturer’s manual for the material you will weld.

SKU 91149 For technical questions, please call 1-800-444-3353. PAGE 7


12. Industrial applications must follow OSHA requirements.

13. Connect the earth ground as near as possible to the operating area. Earth

connections to structural parts of the building or other places distant to the

operating area will reduce their effectiveness and increase the danger of electric

shock.

14. In addition to grounding the workpiece with the Welder Grounding Clamp, an

earth grounding of the workpiece is recommended. Ground it directly to an

earth pipe or grounding rod with a separate cable of appropriate size.

IMPORTANT: Only a qualified, certified electrician should perform this

procedure.

15. Do not touch the welding wire if you are in contact with the workpiece,

ground, or another welding wire from a different machine.

Seller:brw_technologies✉️(5,011)98.8%, Location:Greenwood, South Carolina, Ships to: US, Item:202458490442Argon Fitting Harbor Freight MIG welder 4mm hose to argon BRW-4mm-OXY. Harbor Freight MIG welder 4mm hose to argon adapter,wire welding, BRW-4mm-OXY Do you have a foreign made welding machine that uses a 4mm plastic hose, like those machines made for Harbor Freight and others? Do you need an adaptor to a US standard argon fitting? We have a solution! This fitting adapts 4mm tubing to a standard B-size RH Oxygen Fitting that is used on some imported welding machines and regulators. Designed to thread onto a regulator that uses this type of fitting. Keep in mind that even Victor brand regulators can use an oxgyen fitting as shown by removing the adapter nut. See our other listing for special victor regulator fittings.This fitting will fit regulators that have a standard RH oxygen fitting that has a 9/16-18 thread pitch. Some imported regulators have a non-standard metric thread. Check the thread pitch of your regulator before ordering. To make sure that this will fit your machine, accurately measure the gas hose inside the machine. A 4mm hose can appear close to 1/8", but 4mm will measure .160" and a 1/8" hose will measure .125". The fittings are not interchangeable. Most of the foreign made machines use metric components. Includes: 1- PN BRW-4mm-OXY Does not include any gas hoses, bottles or regulators.
