Purchasing A TIG Welder
TIG welding may be the slowest type of welding out there. But, it is also most precise and easily controlled. The most difficult problem that consumers face when buying this type of equipment is finding a setup that meets their needs and their budget at the same time. Typically, TIG welders are divided into two categoriesâ€”rectifier and inverter. Rectifier welders have been the most widely used for TIG work for a long time. These machines use a transformer or coils to generate the current used for welding. Inverters on the other hand have only been around for about the last fifteen years. But, they are growing in popularity and demand. A circuit board is used to generate the welding current in the case of inverters. One advantage of purchasing an inverter TIG welder is that they use less power than their counterpart, the rectifier. Consider the features of the following types of TIG welders before making a decision about which one to purchase. Small Inverter TIG Welders (110-230v) Most of these TIG welder systems come with the option to operate on 110v or 230v. However, the 230-volt option produces better results with a stronger and more controlled weld bead. Below you will find some options for available Small Inverter TIG Welders.
Thermal Arc 85: This is a very basic 110-volt welder that is a scratch start, meaning no remote start and a hand or foot option can be added. This welder is only DC and will only weld steel and stainless steel when in TIG mode, but can be used for some other
applications in stick mode. Because of the price range and portability of this model, it is an ideal option for around the house and emergency welding situations.
The Miller Maxstar 140 series: Available in 5 different packages, so there are many more options to choose from. Again this is DC only so no aluminum TIG welding. A perfect choice for around the house or where a small portable welder would be useful as in HVAC and restaurant repair and, auto body sheet metal repair; the Maxstar can operate on 110v or 230v. Larger Inverter TIG Welders (110-460v) The difference here is that a larger welder offers a higher voltage for more intense welding jobs and a high volume of welding.
Miller Dynasty 200DX: This option operates using 110-575v 50/60HZ 1/3 phase. Yes it is compatible with any power, anywhere in the world. Lincoln Invertec 205T: This option operates using 110V-230V 50/60 hz single pz. Rectifier TIG Welders Because of the excessive use of power that rectifier welders require, they are being quickly replaced by inverters. However, they are still a very solid and reliable option. For someone on a budget, purchasing a used one of these that has been replaced by an inverter may be the best decision.
Miller Econotig: This is a very reliable and useful entry level TIG and stick welder. The Miller Econotig has been available for many years. It is AC/DC so it can do all metals. Source: http://everlastgenerators.com/wordpress/welders/purchasing-a-tigwelder/
