In fact, if your welding equipment is more than a years old and still running as good as new, it is likely costing you money and if not then it is more dangerous, and may be making it more difficult for your welders.

Today’s welding power sources provide many benefits that can help  reducing in time, increase Easy to trained, deposition rates, and/or reduce weld defects and rework time, today’s power sources. Offer increased power efficiency, which alone may justify their cost.

Electric Shock Can Kill. If Welding Equipment is not proper condition or it has become more old.  Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.

Many welding and cutting operations require the use of compressed gases. To understand these hazards, we must understand that compressed gases are stores of potential energy. It takes energy to compress and confine the gas. That energy is stored until purposely released to perform useful work or until accidentally released by container failure or other causes.

Some compressed gases, acetylene for example, have high flammability characteristics. Flammable compressed gases, therefore, have additional stored energy besides simple compression-release energy. Other compressed gases, such as nitrogen, have simple asphyxiating properties. Some compressed gases, such as oxygen, can augment or compound fire hazards.

Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Before starting check and be sure the area is safe before doing any welding. welding  can cause fire or explosion.

Flying Metal can injure eyes. welding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they can throw off slag.

There are possible hazards such as ARC Rays can burn eyes and skin, Welding can cause fire or explosion, Hot Parts can cause severe burns, Magnetic Fields can affect pacemakers, Noise can damage hearing, Cylinders can explode if damaged.

Considerations about Welding welding automation and the effects of Low Frequency Electric and Magnetic Fields Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to power frequency electric and magnetic fields is a human-health hazard.” However, studies are still going forth and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting.

To reduce magnetic fields in the workplace, use the following Step. Keep cables close together by twisting or taping them,  Arrange cables to one side and away from the operator, Do not coil or drape cables around your body,  Keep welding power source and cables as far away from operator as practical,  Connect work clamp to work piece as close to the weld as possible.

www.weldingtipsandtricks.com Welding Clamps and Welding Magnets can really help in Fabrication and Welding. At first I thought this thing was silly …but it turned out to be one of the handiest tools I have used in a long time. StrongHand Tools are made to work. I would recommend this as an addition to any fabricators tool box

2 of 5 from “Welding” on Modern Marvels from The History Channel. Half science and half art, the ancient technology of welding is integral to modern life. It is the process of bonding, as simple as banging two metals together or as sophisticated as interlinking molecules with sound waves, and without it, the modern world around us – from cars to buildings to pipes that deliver clean water – would not exist.
