Welding itself can be an attractive hobby, or it can be a useful skill for DIYers, auto mechanics, home engineers, craftsmen, and artists. Unfortunately, no one type of welding is suitable for all tasks. The different types of welders can cause confusion for those who are just getting started and those who want to improve their skills or upgrade their equipment.

If you want to know what are the different types of welding and the uses of welding types, please read on. In this article, we will introduce each of the four different types of welding that may appeal to DIY users, discuss their advantages, and look at some of the best machines in each category.

MIG welding is undoubtedly the most popular welding type for DIY users, and it is also popular among professionals. The welding wire is fed into the welding gun from the spool. The feed rate is variable, providing excellent control, and the welder can focus on the welding itself. It is the easiest welding technique to learn. Beginners can quickly make strong welds with almost no cleaning work.

The only real disadvantage of MIG welding is the need to supply bottled gas to form a protective "shield" around the weld and prevent contamination. It is not difficult to set up, but the portability of MIG welding is not as good as some alternatives.

Best for: general workshop welding of steel or aluminum.

Our recommendation: Lincoln Electric Weld Pak 140 Amp-buy at The Home Depot for $649.00. Lincoln Electric is one of the leading brands of DIY and professional welding equipment. This high-quality device combines the ease of use for beginners with the functionality and precision required by more experienced users. It can produce two kinds of welds. In addition to efficient MIG welding, it also provides a flux core function (see flux core welding below).

The main difference between MIG and TIG welding is the power spool without welding wire. The weld is formed by tungsten electrodes and is gas shielded in the same way as MIG. Filler wire is usually used, but "self-generating" welding simply fuses two pieces of metal together.

TIG welding provides greater versatility. It can be used for steel, stainless steel and aluminum, so-called "soft" metals such as brass and copper, and more specialized materials such as magnesium and titanium. Some TIG welders have a foot control device that allows precise adjustment of thermal control. Skilled users can use these steel welders to produce clean, high-quality welds on thick or thin materials.

However, the simultaneous use of welding torches, filler rods, welding torches, and possible foot control make TIG welding more difficult to master than MIG. This is also a much slower process. Not recommended for beginners.

Most suitable: precision welding of various metals.

Our suggestion: Primeweld TIG225X 225 Amp welder-buy TIG machines under $825.00 on Amazon, less than $500, but we recommend DIY welders with a moderate budget to invest in MIG. This powerful Primeweld machine uses inverter technology to provide consistent and controllable power, so users can take full advantage of the versatility of TIG. The comprehensive welding kit is equipped with high-quality welding torch, foot pedal, gas regulator and basic mask.

Bar welding has existed since the late 19th century. Before MIG became affordable, it was the favorite soldering method of many DIY users. Basically it will melt a metal rod (rod) into the joint. The rod contains the components required for shielding, so there is no need for a separate gas supply, and it works well outdoors. It is usually the type of welding machine recommended for welding cast iron, suitable for steel. It will weld dirty, rusty or painted surfaces. Although it can be used for other metals, the high power generated makes it difficult to weld thin materials.

Starting the arc (starting welding) can be challenging. Using rods instead of continuous spools means that this is a stop/start process. It also generates a lot of spatter (molten metal spatter), and if a neat finish is required, it will cause the weld to be untidy and require a lot of work. In essence, this is fast and dirty "agricultural" welding.

Best for: Dirty or rusty metal, where neat welding is not particularly important.

Our recommendation: LOTOS LTPDC2000D Rod Welding Machine, TIG Welding Machine and Plasma Cutting Machine-Buy it on Amazon for $489.00. Lotos is a brand known for its competitively priced high-performance welding equipment. This model provides great flexibility because it provides rod and TIG functions, and can be used as a plasma torch for metal cutting (compressed air supply is required). The focus is on arc ignition, which helps overcome one of the shortcomings of bar welding.

Flux core welding is much like MIG welding, using a spool to feed the welding wire into the weld. In fact, many machines, such as Lincoln Electric above, provide MIG and flux core functions.

The difference lies in the wire itself, which has flux on the outside. This is a solid that is heated until it comes into contact with the weld, at which time it will release inert gas and produce a protective layer similar to MIG welding. However, it does not require bottled gas, hoses and regulators. This makes it a more portable solution. The protective cover is less affected by wind and is an ideal choice for outdoor welding. Like bar welding, it will weld metals that are in poor condition, so almost no preparation is required.

The disadvantage is that the wires are more expensive and the spatter is difficult to clean up. In addition, the rapid penetration provided by flux-cored welding is very suitable for thick materials, but inexperienced users may directly burn through thin plates.

Best for: outdoor maintenance and construction.

Our recommendation: Goplus MIG 130 Welder-Buy the budget-friendly Goplus MIG 130 on Amazon for $149.99. It provides beginners with everything they need to get started, including an airless welder, basic mask, brush/chisel hammer And spools. It is a lightweight and versatile introduction to flux core welding, but more experienced users may require more power.
