It is obvious that Arc welding is considered as the major and an essential part of all the industries involved in designing and infrastructure. But what arc welding is? It is a process of fusing two metals by applying intense heat. This welding type used welding power supply in order to create an electric arc between base material and electrode. And, the final product that develops contain all the properties, just as in metals. The term arc welding is named because the heat that is used during the process of melting the metal at the juncture of joining is caused by an electric arc. With the help of a mechanically guided electrode, carrying the current between tip and the joint leads to cause of electric arc. Listed here are some of the arc welding tips and techniques for the beginners.
So let’s assume that your machine is using a 10 minute time cycle. This means that you can weld for two minutes at full power (20%). Now for the rest of the time which is eight minutes you cannot weld at all, you have to let the machine cool down. This is definitely one thing to look out for when you go to buy a mig Welding Machine China.
First off you will want to spend some time preparing the surfaces. You can use an angle grinder to clean up the edges and remove any rust, old weld or dirt. Using the angle grinder it’s also helpful to make a 45 degree chamfer along the edges you plan to weld. This will help to achieve a strong, deep weld.
One of the important decisions one has to make is whether to buy new equipment or going for used welding equipment. There are many manufacturers of these equipments – Miller, Lincoln, Esab, Hobart – so which one is the most suitable for your needs. You might also have the question whether to go for all in one machine that can be used for multiple processes, or buy a separate machine for each process? You need to decide between Oxyfuel cutting outfit and plasma cutter; air compressor or electric grinders etc.
Make sure the machine is equipped to run in extreme conditions. The machine should not give up and stop working when it is either too hot or too cold. This would be a feature that should be given very close consideration. This can be a very big fall out if your machine pulls you down when the temperature is not suitable for it, because work doesn’t stop then.
This is rated in a percentage, so for example 20%, 30% and 40%. What this tells you is that how long you can weld for in either a five minute block or ten minute block of time. So if your machine is rated at 20% duty cycle you could only weld at full power for 20% of either 5 minutes or 10 minutes. The trick here is to know what time frame your duty cycle is rated at.
Anything worth having requires focused work. What do you think a heart surgeon concentrated on learning while in school? That’s right, heart surgery. Focus on the one thing that will make you money and burn it up like a laser beam! OTS! “Own The Skill!” Be careful NOT to waste time, money and effort on things which will not ever make you money, or which will make you very little money! DO what others are unwilling to put out the effort to master.
A wire feed welding machine will also use consumables. The main consumables that you will need to keep buying will be your contact tips, nozzles and shrouds and gas diffuser. There are other consumables that do need replacing but not so frequently. They are your liner, contact tip holder and maybe a few O-rings depending on what model welding torch you use.
