• Do not touch any wet surface when operating the plasma cutter equipment
• Don’t use plasma cutters without any proper protection
• Wear ear muff when operating plasma cutting system, since it generates high noise levels
• Do not touch the body or object when the system is operating
• Don’t remove the ground cable which is attached with the work object
• Ensure that there is proper earth, since it connects with high electric circuit
• Wear proper protective clothing’s such as welding helmet and gloves
• Make sure that you are working in a well ventilated area
• If you are a heart patient and having pace maker, then consult your physician before you going for work
• Do not make any body contact with plasma arc cutting system
Plasma arc cutting is an easy process if you follow these safety precautions

MIG welding wire types
Monday, June 28th, 2010In metal fabrication and production, the MIG welder is commonly used owing to its versatility and efficiency. To control the amount of filler metal added to the weld puddle, the MIG welder uses welding wire fed from a spool. Diameter, alloy and type are used to categorize the MIG wire.
It is necessary that the alloy of the MIG wire must match the base metal being used. This would ensure that a strong weld would not crack or weaken when cooled. As a wide variety of alloys are available for MIG welders, welder would have the option to weld carbon steel, stainless steel and aluminum. A MIG welding wore would have the name of the alloy, diameter and type of the wire marked on a label. The label would be visible while attached to the welding machine as it is located on the side of the wire spool. Even though the wire type would be marked on the label, each manufacturer has a different way of making wire type. The two distinct type of MIG welding wire are the solid core and the flux core. Solid core MIG wire is a solid strand of the chosen alloy while the flux core MIG welding wire has a flux paste inner core would be surrounded by the filler metal.
Where are stick welding used for?
Friday, June 25th, 2010Welding makes the work easy and many people relay on this for welding. The process of using covered electrode is known as stick welding. It is other wise known as Shielded Metal Arc Welding (SMAW). This is more commonly used by the people than other arc welding. That’s because these are flexible and also versatile. These are known as versatile because they can weld metals together very fast. These are easy for welding once you practice for it. These are generally used for small repair work around the house of individuals.
The merit of this welding equipment is that these are inexpensive than other welders. These are very smooth and comfortable to use and are also portable for welding. The flux in most of the welding equipment needs regular regulating. But these don’t need regulating because here the electrode does this work. These are very less susceptible from any kind of wind and drafts. These can be welded from any angle or position for welding metals.
Wire feed welding for the beginners
Thursday, March 11th, 2010Are you a novice welding operator who is in constant dilemma to select the best welding machine for your task? Well, your confusions can be easily cleared if you get to know about the benefits of using a wire feed welder. Usually the beginners would tend to start their welding process with either stick welder or wire feed welder. However, the wire feed welders have some benefits over stick welders.
In wire feed welders, the wire is fed in a continuous process and this initiates higher productivity. But in stick welders, you need to change electrodes during welding. Secondly, the wire welding requires only lower skill levels and can be learnt quickly while in stick welding, the coordination of hand movements is essential. These reasons make the wire welding most appropriate for the first timers.
Once you select the wire welding process, next you have to go for the type of wire welding that you need. There are two types generally; the MIG welders and flux core welders. MIG welder is capable of welding a variety of metals including thinner ones. And flux core welder would be the best if you want to weld thick materials. In addition, portability and convenience would be more in flux core welders.
What are the fundamentals of a Stick Welder?
Thursday, February 5th, 2009There are various forms of welding processes, however here we discuss the Shielded metal arc welding or stick welding procedure and machinery. The stick welding process uses an electrode that is considered consumable one that can be destroyed or wasted while it is used. An electric current flows from the power supply causing an electric arc between both the metal and the electrode holder. The electric arc is when a surge of electrons are caused to flow amongst two points and then it is divided by gas. The electrode coating or flux coat will melt away, releasing vapors creating a shielding gas and forming a slag, all designed to protect the weld area from the damage the air can cause. The air will damage the strength and quality of the weld area if not protected. The weld area is usually the material the being welded by the operator and usually the manufactured good or goods.
This stick welding procedure generally begins when the welding torch is swept across the source material in a sweeping motion or back and forth. Next, the welding torch will be pulled away by the welder, some describes these actions as similar to striking a match. Once you have the arc, they will began melting the material, causing the waste from the disintegrating electrode to drop small liquid drops. After the shielding gas has been initiated and the vapors start protecting the meld, the slag will rise and solidify. This hardened waste material will have to be chipped away to reveal the finished product. That is the basics of the stick welding procedure, one that is more detailed in steps compared to others and not considered, highly efficient.
The equipment needed to complete a stick welding project would include the welding power supply, electrode holder, a work clamp, and typically welding cables. The power supply used by a stick welder usually has a constant current output. It is with the stick welding process or while using a stick welder machine, the worker will hold the electrode torch, unlike other types of welding procedures.
There is a variety in types of electrodes that the worker would choose and it depends on the kind of weld material, position, and other needs for the project. There are three groups that most electrodes fall under and they are: fast-fill, fast-freeze, or fill-freeze. The fast-fill electrode group are meant to melt away very fast so that they can help to maximize the speed of the welding process. The fast-freeze electrode group is meant to supply filler metal that will coagulate quickly. The fill-freeze electrode group is called the intermediate group of stick welder electrodes.
Using these materials along with the stick welder, you can work in the Construction industry or Industrial and Repair industries. The popularity of the shielding metal arc welding machine and processes are said to be the most popular around the world. Having the ability to be able to be used in numerous positions I am sure has been a factor that has lead to its popularity overall.
