Welding is the most economical and reliable way to join the two metal pieces permanently using the application of heat. It is quite quick and easy to learn process for any beginner, but it involves many considerations from safety precautions to the selection of welding machine.
Importance of Buying Welder for Beginners
Whether you are a do-it-yourself kind of person or a hobby welder with little welding experience, it is important to purchase the welder that suits your project. It is one of the important long-term decisions that can save you repair costs, add extra income to your bottom line and make it possible to fulfil a wide array of DIY projects.
From many welder options available, it becomes difficult to choose the best one that matches your requirements and project specifications. To make it easy for you, we have put together this guide which covers the overview of welders and factors to help you buy the perfect welder. Let’s take a look!
Different Types of Welders and Where They Can Be Used
Each kind of welder has its own benefits and limitations. Here are the most commonly used welders to help you initiate your next project or fulfil your desire to weld in a significant way.
1. MIG welder (Metal Inert Gas)
MIG welding machine is also known as Gas Metal Arc Welding (GMAW). It is one of the easiest types of welding for beginners to learn. In this welding process, wire is used to join two metal pieces that is attached to an electrode current. Also, along with the wire electrode the shielding gas is utilised, which will produce heat to join the two metals.
Apply constant voltage and direct current power source while using a MIG welder for your project. Generally, this welder is suitable for fusing stainless-steel, mild steel as well as aluminium. You can purchase this welding machine when you don’t want to spend money on expensive equipment.
2. TIG welder (Tungsten Inert Gas)
TIG welding i.e. Gas Tungsten Arc Welding (GTAW) is extremely versatile, but difficult technique to learn, so it requires expertise to execute the welding process. In this process, a non-consumable tungsten electrode is used which is responsible for heating the base metal. As a result, it will create a molten weld.
By using lower amperage in the TIG welding process, you can easily work with thinner pieces of metal, which is less susceptible to the damage. It is most commonly used to join thin sections of stainless steel, alloy steel and nonferrous metals including copper alloys, magnesium and aluminium. If you want to have control over the welding process, providing the high-quality welds, then TIG welder is best for you.

3. Stick Welder or Arc Welder
Stick welding is also referred to as shielded metal arc welding which is most popular method for home-shop welding requirements. This process utilises an electric current to form an electric arc between the stick and the metals to be joined. It is one of the effective methods for welding most alloys and joints. Also, it is often used in the construction of steel structures. You can use stick welder indoors and outdoors or in drafty areas.
Being the most economical welding process, a stick welder offers you the capacity to create an efficient bond on rusty metals. These welders are available in AC, DC, or AC/DC, in which AC is the most economical. But, you can use this welder to weld the metals which are no thinner than 18-gauge and thicker metals of 1/16 inch or greater. Stick welders are the best choice for the farmers, hobbyists or any DIY user.
Choose a Welding Machine That Suit Your Needs
In order to choose the best welder, it is important to identify the type of your project and materials that you will require most of the time. The projects might be some fabrication work need to be done on your old motorcycle or some basic repair work on metal equipment.
Not every welding process is suitable to weld all types of metals. So, take time to identify the type of project as it will help you determine the precise thickness of metal and its type. As a result, you are able to select the most suitable welder that matches your project requirements.
Factors to Consider While Choosing the Effective Welding machine
As a DIY welder, it is great to know various aspects of choosing the suitable welding machine. Below-mentioned are some of the important factors to keep in mind while selecting the best welder:
When you are planning to purchase your first welding machine, always keep in mind your budget. This will able to buy the exact type you always wanted and prevent you from the unplanned purchase of the different types.
This is one of the important considerations as it will enable you to have the expected output. Welders have varied power output. So, you have to be specific on the specifications of welder that you need for your project. Choose the welder with more amps as it will have more power to perform heavy-duty projects.
While choosing any particular type of welder, know the exact time the welder will work before it is off. A welder with a small duty cycle requires less time to run.However, considering the welder duty cycle will help you determine the cost of a welder, as there are welders that are expensive but they can run continuously.Choose the welder with long duty cycle when working with thicker metals.
After the selection of welder, when you begin your first welding project, include the welding accessories from helmet, gloves, welding apron to safety shoes. Take safety precautions to complete your project successfully.
