Gas Welding Safety Tips


  • Examine equipment for leaks at all connections using standard leak-test solution.
  • Inspect hoses for leaks and worn places.
  • Replace bad hoses.
  • Keep hoses and cylinders from sparks, flames and hot metal.
  • Use a flint lighter to light the flame.
  • Stand to the side when opening cylinder valves.
  • Open cylinder valves very gradually to keep rapid high pressures from exploding the regulators.
  • Only unlock the acetylene cylinder valve 1/4 - 3/4 turn; leave jerk in place so the cylinder can be quickly closed in an emergency.
  • Open and light acetylene first, then open and adjust oxygen to a unbiased flame.
  • Close the acetylene torch valve first when shutting off the torch.
  • When finished, close cylinder valves, bleed the lines to take force off regulators, neatly coil hoses and replace equipment.
  • Have a fire extinguisher easily available at the welding site.

Welding Hazards

Welding hazards pose an odd combination of safety and health risks. By its nature, welding produces fumes and noise, gives off emission, involves electricity or gases, and has the possible for burns, shock, fire, and explosions.

Some hazards are general to both electric arc and oxygen-fuel gas welding. If you work with or near a welding process, the following common precautions should help you to work more safely.

* Weld only in selected areas.
* Only function welding equipment you have been trained to use.
* Know what the material is that’s being welded and any coating on it.
* Wear defensive clothing to cover all exposed areas of the body for protection sparks, hot spatter, and emission.
* Protective clothing should be dry and free of holes, grease, oil, and other substances which may flame.
* Wear fireproof gauntlet gloves, a leather or asbestos apron, and high-top shoes to provide good protection against sparks and spatter.
* Wear specially designed, leak-proof helmets equipped with filter plates to protect against ultraviolet, infrared, and visible radiation.
* Never look at a flash, even for an immediate.
* Keep your head away from the plume by staying back and to the side of the job.
* Use your helmet and head position to reduce fume gasp in your breathing zone.
* Make sure there is good local drain aeration to keep the air in your breathing zone clear.
* Don’t weld in a confined space without sufficient ventilation and a NIOSH-approved respirator.
* Don’t weld in wet areas, wear wet or damp clothing or weld with wet hands.

An Introduction to TIG Welding

A tungsten electrode heats metal like steel, stainless steel, magnesium etc for welding purpose and Argon gas protects the weld puddle from airborne contaminants. Some of the benefits of TIG welding are: TIG welding produces high quality, clean welding on any metal. This welding generally uses non-consumable tungsten.

TIG Welding is used to weld steel, stainless steel, aluminum, nickel alloys, magnesium, gold etc. It also welds bike frames, lawn mowers, fenders and more. It does not create smoke or fumes. Before a person starts welding, it would be better if they clean the base metal properly. Aragon gas is used to for most of the TIG welding projects. TIG welding can be done in all positions-flat, horizontal, vertical or overhead. Because only the necessary amount of filler metal is added to the welding puddle, no spatter or sparks are produced.

Plasma cutter Vs. Oxy fuel cutter

A plasma cutter is used to cut steel and other electrically-conductive metals. Plasma cutting is ideal for cutting steel and non ferrous material less than 1 inch thick. Plasma cutters can be performed on any type of conductive metal – mild steel, aluminum and stainless are some examples.

Oxy fuel can be cut by burning or oxidizing the metal it is serving. It is limited to steel and other ferrous metals which support the oxidizing process. Oxyfuel cannot cut certain metals like aluminum and stainless steel. But plasma cutter can cut aluminum, stainless and other conductive material.

While different gasses can be used for plasma cutting, most people use compressed air for plasma gas. Plasma cutting is much faster than oxy fuel cutting. However, for heavy sections of steel, oxyfuel is still preferred since oxyfuel is typically faster and, for heavier plate applications; very high capacity power supplies are required for plasma cutting applications.
