With the advancement of modern civilization, we can now enjoy a lot of things. If you know behind the making of different devices, welding has a vital role. There are a lot of welding techniques available to meet different requirements. Among them, the best multi process welder is famous for its multi-purpose use and simple function. Also, the mig welder is a versatile machine that can control the power and speed. Now, as a beginner, you might be thinking about how to use a mig welder. This article will lead you to step by step instructions about using a mig welder.
What is Mig Welder Welding?
A mig welder is a machine that welds through constant solid wire electrode to create an electric arc form between the electrode and workpiece metal. The heat of this machine helps to melt the metal and join them together. A mig welder can be used on ferrous and non-ferrous metal for welding. This machine has an external container that supplies the heat and shielding gas. Mig welder is the easiest welding machine for learners or new beginners.
Difference between the Flux core and mig welding:
A mig welder and A flux core welder machine are almost similar, but some of the functions are different from each other. Some advantages and disadvantages differentiate these two machines from each other. The core difference of these machines is that mig gets its shielding from the air, where the flux core gets the shielding from its flux point. The rest of the difference discussed below.
- Flux Core Welding:
A flux core is an automatic and semi-automatic welding process to create an arc form between two objects. It uses a wire, with a flux-based center, which needs a constant voltage to weld. You can use it outside in the wind area. Or in heavy drafts. As there is no extra container attached to it, it is lightweight to carry outside. Because of its high-speed capability, this welding machine is used in manufacturing, shipbuilding, or underwater.
This welding machine only uses ferrous metal to weld. Even the flux core welder produces some high noxious toxic fumes while welding. So, this machine needs enough ventilation system to clear the fumes.
- Mig Welding:
The mig welder uses solid wire for welding any metal. This machine can adjust with any ferrous and non-ferrous metal. It is easy to use, and the welding process is faster. MIG welder is flux free, so it can not catch any slag while wielding. The penetration is excellent in this machine, which delivers smooth, secure, and best service. Though the MIG machine is cheap, an extra container adds extra value to this machine.
If you want to use it inside the room, then the machine is perfect. But, outside the room, this machine is not suitable at all. Because of its extra equipment, this machine is not so much of a portable one.
Benefits of Mig Welder Welding:
People prefer mig welder for its high-quality services at a minimum cost. Most of the benefits depend on the objects that you are going to weld, and For what purposes you want to use the mig welder machine.
- Speed – The speed of the mig welder is so good that at a first learner, you will not feel any problem while welding. The fastest service of this mig welding machine keeps it different from others.
- Aesthetically Pleasing – If you start to weld with a mig welder, you will notice that the slag and chip are not spattering around the objects. The gas of the machine automatically clears the area, so that you will feel aesthetically pleasing while wielding.
- Weld Settings – The mig welder provides a controllable settings option. You can adjust the amperage power for cutting the thick and thin metal as you want. You can also increase and decrease the speed of the machine.
- Power – You can run the mig welder with various types of energy. You can use the 110 v power at home or 220 V in the garage as you want. Also, use the three-phase control in the shop if you like.
- Versatile – The mig welder can use to weld all kinds of ferrous and non-ferrous metal such as steel, copper, aluminum, nickel as well as iron, and their alloys. You can also use it for personal use as well as for business purposes or in the industry like automotive.
- Simple to learn – This machine is famous for all of the users for its simplicity. You can have basic training for about twenty minutes and can run the machine swiftly. It is so easy to learn for a beginner.
Note – Based on the benefits and functions, you can choose the mig welder as your first instrument in the welding area.
How to Use A Mig Welder?
The mig welder is the best multi-process welder in the welding machine area. Because of its versatility and faster productivity, the mig Welder machine is different from the other welding machine. To know the use of mig welder machines you can follow the step by step guidelines.
- Learn about the Mig welder:
To use a mig welder, you need to learn about the machine first. Then, acknowledge the equipment and the gas tanker and how it works. Gather all the information about how it contains. You have to know which metal you can weld through a mig welder. This learning process will help you to understand by which objects you can work.
- Safety Dress:
Before using the mig welder, wear a safety dress. This dress will save you from accidents or burning skin. Gather a fire extinguisher and a bucket of sand if any fire occurs.
- Prepare the Weld Area:
Select the object that you want to weld and prepare the area for welding. Remove all kind objects from the surface that can make fire. Check the power connection before welding.
- Installation Process:
First, select the weld material and then select the same wire. For example, if you are welding a nickel object, then select the nickel wire. If the object is thin, you can choose the thin wire and for thick objects use a thick wire. Prepare the reel by tightening the wire. Keep the wire straight to avoid the tangle and use a wire cutter to cut wire accordingly. Before putting the wire into the tube, clean it with a tidy cloth. It will prevent you from bad welding. If you have to put the wire forcefully, then you have to understand that the wire is not aligned, put the wire properly. Now press the on button to run the welder machine. Adjust the tension while welding. Keep your tension as low as possible. Otherwise, it will damage the object.
- Finish The Process:
Now, if everything is ok, go for the welding process. Check the power connection. Use the proper shielding gas for proper penetration on the objects and the proper angle for mig welders. It should not exceed 10 degrees or else your control power on the welder machine will fail.
Note – This is an effortless way to show you the guidelines for using a mig welder. As a learner, you can follow the steps and try to use the mig welder.
How to Avoid Common Mig Welder Problems?
There are indeed lots of benefits of using mig Welders for welding. But, while welding there can arise some common problems. To avoid these common problems, you need to be careful. Some of the common issues and its remedies are here-
Problem 1 (Overheating) – If the mig welding machine is overheating, then it will provide you incorrect cable size and duty cycle.
Remedy- Change the cable of the mig and read the instructions.
Problem 2 ( Shocks) – Sometimes, electric shock occurs when you touch the welder machine.
Remedy – The welder machine needs to ground correctly to prevent shock. Also, check the connection and repair short circuits.
Problem 3 (Bird Nesting) – If you are a mig welder user, you will often see the cable is tangling, which leads the wire feed to stop the work.
Remedy – To avoid this problem, keep the wire at lower ground and roll back the cable at first.
Problem 4 (Back Side Burn) – Sometimes, because of the overvoltage backside of the welding machine can be burned.
Remedy- You can use the plodding wire to avoid this problem.
