TIG Welders – Lightweight Welding Power

tig weldersTIG welders are commonly available as a Tig AC/DC power source that allows manual electrode welding as well as TIG welding. Modern machines contain microprocessors that give full digital control that results in perfect tig welds. TIG welders of this nature are rated from around 170 A to 300A, they are lightweight, portable and excellent welding machines suited for construction and maintenance work.

Larger TIG welders will run from 400 to 500A output. Machines of this nature also fully digital controlled. Applications include plant construction, aerospace and shipbuilding, pipeline construction and installations

When TIG welding, the operator has more control over the whole process of welding. Unlike other welding types Tig welders use tungsten electrodes that are non consumable. Tungsten is used as the melting point is extremely high, allowing the operator to introduce a filler rod to the weld. Many in the welding industry use tig welders to weld non ferrous metals such as magnesium, copper, and aluminum as well as stainless steel.

The Advantages of TIG Welders

The electrodes used with TIG welding are non-consumable, while other types of welding, like tig welderarc and mig welding use electrodes that are consumable. There are advantages with both methods but with TIG welders there is no need to stop in the middle of a project and replace the rod that has been used up. As one might expect, stopping at a critical point can cause an imperfection in the quality of the finished product. With the undisturbed work that can be done with the TIG system, the overall quality is much better.

TIG welders are a good choice when working with non-ferrous metals like copper, magnesium, and aluminum.

Minor disadvantages of TIG Welders

If you have ever wondered why there are so many different welding techniques as well as equipment, the answer is simply that there are different situations that require welding of a different kind using an array of different equipment. For this reason tig welding is a somewhat specialized feild.

For one thing, TIG welding is more complicated and requires more skill and better training in order to carry it off right. The welder using a TIG welding machine must have much greater accuracy and control in directing the tig torch and using the filler rods. Maintaining the arc in the correct position and the right distance from the piece they are working on is critical.

Welding with a tig machine is more time consuming than most of the other methods, but you must remember that this time means the finished work will be much higher quality, making it worth the time it takes to complete. Wearing a quality welding helmet is essential as the arc created from tig welders is much brighter than conventional welders.
