The Top Things to Take Care of When Using a Welding Machine

Welding is done to join two pieces of metal together through heat or pressure or both. After the metal pieces have been joined, the joint is sometimes even stronger than the metal involved in it. Welding techniques are still commonly used in factories these days. But a lot of care must be taken while welding as, if not taken proper care of; it may result in various hazards like electric shock, fire, or even explosions.

Commonly used Welding Techniques

Following are the popularly used welding techniques in the factory and the hazards associated with them.

Arc Welding:

You have the metals joined by passing an electric arc between a metal electrode and the joining metals.

The heat produced by the arc helps in joining the two metals together by mixing the molten deposits of the electrode on them. The equipment needed while arc welding includes a power supply, electrode holder, protective shield, clothing, and ground clamp. The hazards involved in arc welding are an electric shock, UV burns, and burns.

Gas welding:

A gas flame is directed over the metals so that they melt and form a puddle. The metals are then brought together and joined on their closest surfaces. Gas welding is most commonly used for general maintenance and soldering as it is easier to control. The hazards involved in the gas welding are burns and fire.

3.    Oxygen and arc cutting: Cutting is the phenomenon to remove the welded metal with the help of flame or arc. The metal can be melted by a gas flame and then cut off by an oxygen jet. Another method is to generate a lot of heat with the help of an electric arc and then melt away the joint.

Precautions To Take When Using the Welding Machine

Welding machines are high-risk machinery, which works fast and is difficult to control. To avoid any hazards like fire, UV burns, or electric shocks, here are the top precautions you must take:

1.    Always wear a face shield:

A welding shield must be worn during the process so that the heat or the light doesn’t affect the face. The spark from the welding machine can enter your eyes and damage it. If going for an arc welding, the UV rays used to make the metal are brighter than the rays produced by the sun.

As a result, it must not be looked at endless wearing a welding shield with the filter plate of shade 10 or higher. If you are just observing the welding, you should still wear a cardboard mask with shade ten filter plate.

2. Always wear close-toed shoes:

Make sure that you’re wearing close-toed shoes during welding so that your feet are protected from UV rays or fire. Closed toed shoes also help in protection in case of any electrocution that might happen. Covered feet also help in protecting you from any harmful rays while you are observing the welding process.

3. Always wear non-flammable clothes:

Gas welding especially can cause fires as it is fueled by oxygen. Therefore, always make sure that your clothes haven’t been around any flammable materials before you go for welding. Make sure that you wear full-sleeved clothes so that any part of your body isn’t exposed to heat to cause any burns. If you are around an area where welding is taking place, make sure the curtains are drawn around the welder to not expose your skin to UV rays. Also be sure of wearing full-sleeved clothes to protect you.

4. Always wear earplugs:

Welding areas usually produce a lot of noise and earmuffs or earplugs must be worn to avoid that noise. When using arc for welding, it is possible that a spark might enter your ear canal and damage your eardrum. A damage caused to the eardrum seldom heals. Therefore, to protect your ears, you must wear earplugs.

5. Always wear wielding gloves:

Both gas and arc welding can cause damage to your hands if left exposed. The heat produced during welding is enough to cause harmful burns that may damage your hands for a very long time. Special care must be taken while working with an arc as it makes use of UV rays. The metal also remains quite hot even after the process is completed. The heat travels throughout the metal in case of strong conductors like copper and Aluminum. Therefore, gloves must be worn to protect you from any kind of burns.

6. Don’t clean on surface with chlorinated hydrocarbon:

Chlorinated hydrocarbons like brake cleaners can react with UV light to produce phosgene gas. This gas can poison you or cause serious damage to your body. Even ventilation does not provide enough protection from this gas. It is, therefore, of utmost importance to never weld near or on a surface that has been cleaned using a material consisting of chlorinated hydrocarbons.

7. Make sure your bench is dry:

A Puddle of water on the floor or near the area of welding can result in electrocution. Therefore, always make sure that your bench is dry and so is the nearby area before welding. Same care needs to be taken with the welding machine, the torch, the plug, and the pedal.

8. Store gases carefully:

The gas welding involves a torch that is fuelled by oxygen or air for welding. For that, you would need gas cylinders in the welding areas. Carbon dioxide and argon are part of the atmosphere but can cause asphyxiation and death, if exposed in an enclosed area. Thus, one must always keep the gas cylinder in an upright position and make sure that the cylinder is covered with the non-flammable material.


Always worried about whether you would be able to work with a welding machine? Don’t be. It’s all about how you handle it. Using your welding machine is a lot easier than you would think. Just follow these five simple tips, and you are golden! Read also the tool belts review
