MIG/MAG welding wire coil

In the welding sector you can find different processes to obtain the same result. This is what someone with little knowledge of the various welding processes may think.

A more educated public knows that every welding process is designed for a specific process to obtain a different result. It is also very important to consider where the operator is going to weld.

Each of these processes MMA, TIG, MIG-MAG is better suited to a specific application than others.

The MMA process, also known as covered electrode welding, is suitable for working in the open air or in isolated places, because the equipment needed is easy to handle and does not require a gas shield to obtain satisfactory results. This process cannot be called clean, because during electrode melting there are metal spots and slag that must be removed at the end of welding. This process has a low efficiency. In fact, the operator is forced to interrupt the work process in order to replace the electrode and complete a large weld.

The TIG process is suitable to thin parts which require a great appearance, such as motorcycle or bicycle frames. This welding process is not particularly suitable for outdoor use because it requires a gas shield that may be dispersed by the wind. The TIG process is not recommended for large welds because the operating speed is not particularly great.

MIG-MAG welding is probably the most widely used process in the industrial field, and in the last decade, thanks to the appearance of multi-function welding equipment, this welding process is spreading rapidly in the hobby field as well.

MIG-MAG welding is very versatile, depending on the amperage and the type of MIG MAG welding wire used. This process is suitable for light work, but also for use in heavy carpentry. This process has the highest efficiency compared to other welding methods. It allows very long and demanding welding operations without the need for any interruption to reequip the welding machine. The higher or lower efficiency depends on the size of the wire coil for the MIG-MAG welding machine, which may vary from 700 grams to 15-16 kg.

This welding process is very versatile because it allows the operator to work on different materials with the same welding machine. Simply replace a few consumables to have an easier working process, and by changing the steel wire coil with an aluminum wire coil or by equipping a stainless-steel wire coil you can proceed with the necessary welding.

The consumables that can be replaced based on the material of the MIG-MAG welding wire coil are:

• Steel wire coil: the most common metal and therefore one of the most used, also known as mild steel. Generally, MIG-MAG welding machines are supplied with these consumables to work on this metal: wire roller, contact tips and welding liner are supplied by default for the most commonly used diameters of 0.8 mm or 0.6 mm. If you equip a MIG-MAG welding wire coil with a larger diameter, 1mm/1.2mm, you will need to replace all three consumables listed above. If you wish to replace the steel wire coil with a flux-cored wire coil, it is advisable to install a roller that can pull this very soft wire which, if not combined with a suitable roller, may slip, and create delays.
• Stainless steel wire coil: widely used in the industrial field, this particular metal alloy does not require any particular replacement of consumables. If you use a stainless-steel wire coil with a non-standard diameter, you will have to replace the wire roller, the welding liner, and the contact tips with the right diameters. The ideal gas protection when working with a stainless-steel wire coil is the ArCo2 mixture in a 98% Co2 2% Argon percentage, but a more common mixture of 82% Argon and 18% Co2 is also very suitable for gas protection.
• Aluminum wire coil: often used in body shops or in the window and door frame industry. This very soft and flexible metal requires the use of specific consumables to avoid issues. When equipping the welding machine with an aluminum wire coil, it is advisable to replace the standard wire roller with one specifically designed for aluminum wire coils; the standard metal wire welding liner must also be replaced with one made of Teflon to prevent the wire from jamming during use. The last but not least consumable that has to be replaced is the contact tip, which has to be designed for the aluminum wire coil. Unlike welding with a MIG-MAG welding wire coil, when using an aluminum wire coil, you must replace the classic mixture protection gas with pure Argon gas.

It is often recommended to equip a second torch designed for use with an aluminum wire coil to avoid frequent replacement of the welding liner and consumables, which could become damaged early due to excessive stress.

The MIG MAG welding process, besides ensuring a very high efficiency, is the ideal process for machining operations that require filling even a large gap between 2 joints.

MIG MAG welding, as mentioned above, is the welding process with the highest efficiency because the MIG MAG welding wire coil is the electrode. When the wire is pushed by the wire roller through the wire bundle, it reaches the welding torch and when it comes into contact with the base metal it melts through a series of short circuits.
