Choosing the Correct Tig Welder:
1). Match the metal type you need to weld to the tig welder's electrical input. For example, if you require a welder able of welding "hard" metals like steel or cast iron or bronze, an alternating current (AC) welder will work. AC welders function using electrical energy that "alternates" direction back and forth. If you require welding soft metals like aluminum, you need a direct current (DC) welder. DC electrical energy creates a stable arc for the welder and comes from battery cells.
2). Choose how thick of metal you want to weld. If you want to weld broad metals, you want a welder able of producing high amperages (amps). Low-amp tig welders create 165 to 200 amps. High-amp welders create 310 to 700 amps.
3). Decide if your work place be able to accommodate your welder. Tig welders weigh among 40 and 200 pounds. They calculate from 13 to 36 cubic inches. Different tig welders too need different plug-ins. A few want a standard 120-volt plug-in. Others need a 220-volt plug-in.
4). Compare responsibility sequences. A welder's responsibility cycle indicates how long the welder can work during a 10-minute gap with no overheating. For example, a tig welder that is able to weld for weld minutes but wants seven minutes downtime to cool off has a duty sequence of 30 percent. Duty sequences range from 15 percent to 60 percent.
5). Make sure the tig welder fits your financial plan. Tig welders price from $500 to $2,500, depending on their power.
6). Compare features of welder models. Tig welders come with a diversity of features that include automatic fans and high-frequency arcs. High-frequency arcs assist stay the welder's electrical power stable, which gives an accuracy weld. Choose a welder with as a lot of features as you be able to afford.
7). Compare warranties of welder. Many manufacturers give a two- to three-year warranty. Some sellers also tender a 90-day return policy. In-store return policies are able to make much less hassle.
