What is welding

The welding is a process of joining metallic or thermoplastic materials by melting through high heat. The whole procedure is carried out by the blowtorch, electric arc, and other necessary equipment.

It is different from low-temperature metal-joining techniques like brazing or soldering, where the base metal does not melt. In welding, the metals are molten at the particular portion to join together and need to leave for cooling to make union for sculpturing or fabricating a new pattern.

The crucial thing needs to keep in mind that welding is a risky process. So, the worker must have proper training and need to wear gloves and a welding helmet as protection for atmospheric contamination.

What is MIG welding?

The elaboration of MIG welding is – Metal Inert Gas welding or Metal Active Gas (MAG) welding. It is an arc welding process where the fusion of metals occurs by heating them. The arc produces by continuous feeding of power between the filler metal electrode and the workpieces.

In the MIG welding process, a shielding gas is used to get a clean weld, which is created from the gas tank and the integrated welding gun. This gas shield acts as a protection for the atmospheric contamination. Usually, carbon dioxide is the standard shielding gas for MIG welding.

Advantages of MIG welding

It works fast through a continuous push-pull feed technology.
The process of operation is simple, needs no extra training to handle.
It results in high-quality weld for various types of metal like aluminum, steel, mild steel, stainless steel, nickel, magnesium, copper, and many other alloys.
The MIG welding offers better weld pool visibility and control as it goes through an auto-feed wire.
The shielding gas allows a little loss of alloying elements.

Disadvantages of MIG welding

The cost of MIG welding equipment is comparatively high.
It requires more accessories to weld.
A cart needs to carry the MIG welder.
It does not penetrate the thick metals.
The shielding gas takes time to replace.
The working materials need to rust or dirt-free to get a better result.

How to choose the right MIG Welder 2020

As the MIG welder produces a high level of heat to melt the metals, the cooling procedure must be considered before taking a new one. The arrangement of the welder and the feed gun that influences the cooling system is described below. You need to read this information thoroughly if you want to take the most efficient MIG welder for your next project.

Air-cooled

The air-cooled gun helps to operate the machine comfortably. Because it maintains the balance of surrounded air and the shielding gas and prevents overheat generation that hinders the welding process. The power cable contains more copper that protects the cord from melting. This gun is also cumbersome and limits flexibility. But it suits outdoor welding for its small diameter of wires ( 0.035”- 0.045”). Besides, it does not need extra gas hoses or radiator cooling system. Moreover, the air-cooled gun produces 150 to 700 amps power output that makes it suitable for a wide range of use.

Water-cooled

The water-cooled guns are compatible with the condition where water and hose are available. Helium-mix gas is more suitable to run this type of welder. Though it works as an air-cooled gun, the lightweight offers more flexibility than the air-cooled one. Besides, the water-cooled gun is more durable, delivers 300 to 600 amps, and save more energy.

Push-pull

The push-pull gun helps to weld far from the power source and can work 50 ft away. This gun is designed with a gooseneck and pistol-style grip that helps to accomplish this particular requirement for welding.

Spool Gun

Spool gun reduces the difficulty of pushing on soft wires like small diameter aluminum, stainless steel, silicon bronze. It is suitable for sporadic welding and at low amperage situation.

Fume Extraction Gun

This type of gun is available on the welder with 400 amps or more. It runs by capturing the fume produce at the source, over, and around the weld pool. The extraction regulating system, better shielding on gas flow, and effortless handling features make the fume extraction gun popular among the users.

High Amperage = High Power

The welding gun size depends on the welding dimension, and it maybe 100-150 amps, 200-300 amps, 400-500 amps, or 600 amps. The 600 amps can handle all kinds of welding, but it is highly-priced.

Since the welder with an average power able to consume the stress of any range of welding, you don’t need to spend more money on it. We know the price increases with the power of the welding machine.

So if you have to weld a thick metal frequently, then you can take a welder with a high power capacity. Except for this, you have to check the required power to finish your welding tasks before buying your MIG welder.

Power Pin

As welding is relatively tricky and dangerous for the worker, you have to check the strength of the power pin. A weak power pin may damage if you try to work with a high voltage. On the other hand, a well-built power pin never twists and will enhance the power flow through the gun.

Plug – Multiple Plug Option

The welding work moves with the electric energy and maybe on the house or construction site. So, we do not know the status of the plug on which we have to connect our machine. Therefore, the multiple plug option can solve the problem of adjustability with the power source. The numerous plug option also improves the flexibility of the welder.

Power Cable

It is quite natural to check the strength and length of the power cable before taking a power tool. Depending on the distance of the working area from the power source and the required power for welding, you have to decide which one suits your needs. If you purchase a short and comparatively low-capacity cable, then it will affect the result of welding. Besides, the too-long cable may also be hazardous for the welding area.

Liner

The liner is a simple but essential part of the MIG gun. It regulates the welding wires from the feeder to the contact tips through the cable. It also keeps the gas safe inside the container. So a low-quality liner can cause a leak of gas. The right sized and well-built liner should be chosen for better performance. Not only this, the liner should be cleared out with compressed air sporadically.

Neck

The neck of the MIG welding gun has a significant effect on specific applications of the machine. It also a matter of selecting other components for the weapon to get better performance. The appropriate neck design enhances the access to the weld point, ensures comforts, and also lessens the cost for the welding.

The neck of a gun is crafted with various designs, including rotatable, flex, curved angles and lengths, neck couplers, and conventional neck. Everyone has a distinct effect on a particular application. So you have to choose the right neck for a specific use to get the best welding performance for your MIG welder.

Trigger

The trigger of a MIG gun helps the welder to run electrically. Generally, triggers are available in dual-schedule or lock-out system. Between them, the lock-out system has more control over the welding. It also assists in focusing on the operation, notably during longtime welding. Therefore, the trigger should be strong enough and replaceable to get safe and comfortable welding.

Handle

The small, lightweight, and comfortable handle of a MIG gun will be great for a capable welding machine. It should also have the ability to manage the amps or duty cycle rating of the welder. If it has a ventilation system, then it will help to reduce the heat and thus the productivity will be improved. So you have to choose the perfect one for a better weld.

How to arc weld?

The arc welding is a process of welding where the flux-cored electrode is used to join the metal workpieces. The electrode melts in an electric arc and combines with the welded metals. A fillet helps to complete the entire procedure. In this process, a slag produces that covers the molten metals and also reduces the oxidation. After welding, it cools and becomes a unique part of the new structure.

While welding, the arc moves with a back and forth way to create a bead on the weld path. After every pass, the melted electrode flux elements should remove to get a clean molten metal for the next passes.

Before starting, the rust, dirt, paints, grease, or any other contaminants should be removed from the workpieces because the arc welding is sensitive to the rusty metals. The rod should be positioned at the right angle, and it needs time to finish the whole process. Therefore some technical knowledge and patience required for the arc welding.

How to MIG weld steel?

MIG welding is another form of arc welding where an arc of electricity produces a short circuit between the wire (+ anode)and the metal (- cathode). The arc of electricity generates heat to melt the metals at the weld pool. When the heat generation stops, the melted metal cools down and turns into a new shape.

In this process, an inert gas is used as a protection from the atmospheric contamination and also helps the melting process.

MIG Welding Tips and Tricks

Maintain a ¼” to 3/8” distance between the electrode and the tip of the contact tube for safe welding.
Follow the recommended diameter chart for the thickness of metals to get the best result.
Choose the wires to suit the base metal.

For example, on steel welding, ER70S-3, gives economical welding, whereas ER70S-3 delivers better results for dirty or rusty steel with more deoxidizers.

Choice the shield gas according to the quality of welding metals.

For example, argon for aluminum, CO2, or 75% Ar/25% CO2 for carbon steel, trimix (helium/argon/CO2) for stainless steel.

Always try to place the base metal at the horizontal position.
To get the best results, keep the gun as straight as possible whatever the position is.
Keep all parts clean and tidy, even not in use.
Select high-quality accessories and also as the wire size.
Wear gloves and helmet while welding.
