How to Choose a Good MIG Welder?

Whether you are a professional or a DIY enthusiast, the MIG welder is the accessory you need in your personal workshop. In addition to being effective, this machine is quite easy to use. Among other things, it is the ideal gadget that will help you perfect your metallic creations.

This buying guide section is intended to help you get the best MIG welder for the price on the market. Before finalizing a purchase, try to learn a little more about the following things:

The operating process

The MIG welding machine has a semi-automatic welding process using a neutral gas that does not react with the molten metal. With a very simple but attractive design, it is very practical and also easy to use.

The wire feed is controlled by the trigger of a welding torch, and the closing of an electrical circuit allows the passage of current through the filler metal. This product also allows great flexibility of implementation, which can be used on different types of metals.

The MIG welder can be used for continuous welding with high productivity, but compared to other machines, it gives off slightly smoke. If you want to vary your DIY work, this machine is recommended.

Use of equipment

If you need to know how to buy a MIG welder with a better price-quality ratio, it is essential to wonder about the type of metal that it is able to work. Well before the purchase, it is necessary to clarify whether the machine can cut steel, stainless steel, copper or aluminum.

It is true that this material exists in different models, but each has its specificity. As this accessory is very robust, it has a wide range of uses. Being very sophisticated and very efficient, the MIG welder is the device of choice for professional scrap dealers.

If you are an uninitiated user, try to adjust the power correctly, otherwise the device may be damaged and you may be injured.

The security rule

Whether in workshops or on construction sites, the risks inherent in welding work are always present. Precautions must be taken to avoid breakdowns and welding faults.

First, take time to cool down before any maintenance procedure and keep the device clean from the inside. Dust and foreign matter that have settled on the transformer or diode must therefore be removed periodically. Very important, you must prevent the torch from being knocked or dropped.

Heating power

The heating power is expressed in amperes. But unless you are a professional and want to work on large parts, a 40 to 130 amp welding machine will allow you to carry out all of your metal smelting work. To know how a welding machine works, you have to understand the duty factor. It works inversely proportional to the intensity you choose.

For example, a 60% duty cycle means that the welding machine will allow 6 minutes of welding for 4 minutes of cooling. The walk factor is expressed in amperes against a percentage (60% for 100Ah, to use the example). If it displays 100%, it means that the welding machine does not need rest time, it can operate continuously, without overheating the device.

Thicknesses & type of assembly

Thick metal or thin sheets cannot be welded in the same way. You could do worse than better. As we said, the MIG welding machine specializes in precision work, for the automotive sector, but also for certain artistic works or for quality work.

MIG makes it possible to work on iron, but it is not its primary vocation. It is more suitable for working on metals such as aluminum, stainless steel, etc. The other ways of welding are to be reserved for repair work for domestic use, but also for agricultural machines, etc.

The right price

Our buying guide can only end with an analysis of the costs to be incurred to buy a MIG welder. By comparing the prices, you will notice how the shopping range is rather variable since you can find cheaper models as well as others rather expensive.

Mig welders are for those who make welding their profession or in any case operation to be performed several times a week.

Among these, the automatic MIG models stand out, in which the advancement of the wire and the electrode along the welding line is completely managed by the computer. The low cost models are aimed at hobbyists or whoever thinks of making the appliance a sporadic use.

Frequently Asked Question

MIG or TIG welding machine – what’s the difference?

Regarding TIG, welding is carried out with an electric arc coming from the infusible tungsten electrode with a diameter between 1.0 and 8.0 mm as well as the workpiece. In use, it is possible to manually or automatically bring the filler metal inside the weld pool.

On the other hand, MIG is done from an electric arc which is formed between the filler wire with a diameter between 0.6 and 2.4 mm at a speed of 2 to 20 m / min thus than the workpiece. The notable differences relate to the control of the deposition precision, the welding speed and the type of feed of the filler wire.

How to adjust a MIG welding machine?

In general, there are two types of settings for this kind of station namely 140 amps and 180 amps. With the former, you will have the possibility to weld sheets up to a thickness of 2 mm. It will therefore suffice to make the rule of 3 according to the given amperage.

Regarding the 180-ampere substations, they can be used on sheets with a maximum thickness of 4 mm. You just have to proceed to the rules of 3 in order to know the adjustments of intensity.

MIG welding machine with or without gas?

These two categories of devices are equally powerful. However, your choice should mainly be based on the materials you plan to weld. Note that the use of a gas device is particularly advantageous. This is because you will benefit from more employment opportunities.

Also, many users affirm that this category of station brings a great comfort of use. Be aware that it will take a significant investment to get a gas-powered station.

 What power for a MIG welding machine?

The power of the welding current of this type of device expressed in Amperes or A is variable depending on the device you buy. In general, there are two main categories of trade positions. You therefore have the choice between models from 140 to 180 Amps depending on your welding needs.

Note that the adjustment of this type of device is essential for the success of the work.
