Welding is a process of joining two materials, mostly metals. It is essentially keeping the world around us together as we see it today. welding is fundamental process of most of the industries including automotive, ship building, aviation, construction and aero-space. welding is very challenging and demanding job, if you are one of those who are fascinated by the welding and are willing to buy yourself a welder your are at the right place, following are the top ten tips that you must consider while buying a welder
- TYPE OF MATERIAL TO BE WELDED
First question that you should ask yourself, what am I going to weld as the choice of welder is primarily based on the type of material to be welded. Although there are welding processes that support welding of more than one metals, but the decision should be taken based on metal that is mostly needs to be welded. A table showing metals (commonly used) Vs welding process that it can weld it is given below

- SKILL LEVEL YOU HAVE
To produce good quality weld, choice of suitable welding process and requisite skill level both are equally important. As some welding processes require more time to master other are easy to learn. A table of skill level Vs Welding process is given below

- ELECTRICITY/ POWER AVAILABILITY
Like any other machine welder are also required to be connected to the electricity/ power source. Depending upon the area/ region different electricity supply voltages/ frequencies are delivered to customer. One should be aware of what is available at the power outlet and the decision of the welder should be made accordingly. Following choices are available
Power Available |
Availability |
Type/ Capacity of Welder |
110/120 V |
Utility Customers in Europe |
Entry level welding machines |
220/240 V |
Utility Customers in Asia |
Up to 30A welding machines |
440 V/ Three Phase |
Industrial Connection |
Industrial applications |
- WEIGHT OF THE MACHINE/ INDOOR / OUTDOOR APPLCIATION
Although weight of the machine does not have to do anything with the performance of the welder, but it becomes critically important when application/ usage of the welder demands that machine to be moved around or it has to be carried from one place to another place. For the application where placing the welder is one time job and it is not required to shifted around, physical dimensions are of most importance than the weight of the machine. so consider the machine weight and dimensions before buying.
- MACHINE PARAMETERS
Like any other machine, welding machine do have specifications, maximum and minimum range for certain parameters. A table of typical welding machine parameters is given below for reference only, select the machine that best match your requirements

Current rating defines how thin or thick metal a welder can weld, so choose carefully |
- FUTURE SCOPE OF WORK
There are several different types of welding machines heaving single and multiple process capabilities. Single process machines provides better control over the welding process and less adjustments on the console. while purchasing single process welding machine you should be very sure that it will meet your requirements, else you have to invest on another machine. Once you are in the welding business your interest and skills are expected to be improved, thus heaving a welding machine with multiple process capabilities is a good idea. And the good thing is multi process machines are very common these days. These machines can switch between various welding processes via knob/ settings on the console.
- COST OF ACCESSORIES/ CONSUMABLE
Each welding process has associated list of accessories and consumables. some process require shielding gas, other require flux to protect weld from environmental process during the welding process. If you are welding using MIG, then you have to bear the cost of gas cylinder as an accessory other than gas. However, in case of stick welding cost of empty gas cylinder is not there. Carefully estimate the cost of accessories and consumable to keep the welder running economically.
- MAKE/ COUNTRY OF ORIGIN OF THE MACHINE
There are number of welder manufactures with very tough competition on the price and quality which makes it very difficult to choose from various brands. Famous brands for quality and reliability are EASB, Lincoln and Miller are given as reference only. Your choice on selection of particular brand should be based on availability and cost of replacement/ spare parts in your local market.
- WARRANTY
when buying a new product, everybody want to be sure that it will work for a reasonable period of time. Usually warranty is provided by the seller as repair/ replacement of the faulty product. Do study the warranty terms of the machine. generally one year warranty is provided with the welding machines which are usually not applicable to the damage due to electric shock or if a repair attempt is made by anyone other than authorized dealer/ distributor. Do consider the location of authorized dealer in case a warranty claim may arise.
We have described above the factors you need to consider when buying your first welder, and we will summarize the following:

-
Consider the size and weight of the welder: If you'll be moving your welder around or taking it with you on the go, it's important to consider the size and weight of the unit. A lighter and more compact welder may be easier to transport and use.
-
Look for a welder with adjustable settings: A welder with adjustable settings will give you more control over the welding process and allow you to adapt to different materials and thicknesses.
-
Consider the type of power source: Welders can be powered by electricity, gas or both. Consider the type of power source that will be most convenient and cost-effective for your needs.
-
Invest in safety gear: Welding can be a dangerous activity, so it's important to invest in safety gear like a welding helmet, gloves and protective clothing. This will help protect you from burns, sparks and other hazards.
-
Consider the warranty and return policy: Before buying a welder, make sure to read the warranty and return policy carefully. This will ensure that you're covered in case of any issues or defects with your welder.
Prior to purchasing a welder, it’s crucial to consider the kinds of welding jobs you’ll be working on and the materials you’ll be using. My dad’s an independent contractor who mainly works for friends and family which we all love. For his birthday, I and my sisters want to buy him a welder he can use on projects he takes on so thanks for the guide. I’ll make sure that the Kemppi Welding Machines we buy him are perfect for all the work he’ll do in the future.
