In this article, we will be looking at information concerning tig welders. From what is a tig welder, what task it performs, and what types of tig welders, we will finally look at the factors one must consider when selecting a tig welder to buy. The information contained in this article is relevant and can be used when one needs the machine.
Tig welder is a machine that is used in welding steel and other metallic substances. This type of machine uses gas in the welding of metals and alloys. It also uses a non-consumable tungsten electrode when welding. It welds. Materials made up of copper, zinc, aluminum, and even bronze.
There are two types of tig welders’ machines, and they are cold fire and fire welding machines. The main difference between these two machines is that the cold fire welders use a normal filler fire, whereas the fire heats fire before.
The materials to be welded
Tig welder works under different circumstances. The machine is designed for welding specific types of materials. It can weld some while others cannot based on the formation background. The machine is designed for welding soft metals made of soft metals.
For example, the machine is designed for welding aluminum, copper, bronze, zinc, and more. The machine cannot weld materials such as diamonds. Diamonds are very hard. It is the hardest metal on the planet; therefore, we cannot use the tig welder machine in that case.
The type of current to be used
There are two types of current: direct current (DC) and alternating current (AC).
The type of current to be used determines whether the metal being welded will be successful. For example, when welding soft metals, you are supposed to use alternating current, but when welding hard metals, one is supposed to use direct current. Direct current melts substances like aluminum, copper, and bronze.
What is the difference between the lift tag and the high-frequency tag?
While operating the machine, one is supposed to know the difference between the two parts of the machine; failure to which one can cause accidents while performing the duty. The lift tag of the tungsten electrode should touch the metal, and the current should be low so that the electrode and the work-piece do not touch each other.
The tungsten electrode should touch the metal slightly at a high frequency and apply a high current. This helps the machine user minimize the chances of an accident using the machine.
How to use the tig pedal with the tig welder
Before buying the machine, one is supposed to know how to use the tig pedal of the tig welder. The reason behind this is that it minimizes the chances of the occurrence of any accident while performing the task of welding. The tig pedal is part of the machine that you keep rotating using your toes for the machine to keep working. It accelerates the rate of executing your duties and is helpful in terms of speed.
In conclusion, the above factors are some of the factors one has to consider when one needs to buy a tig welder machine.
