tig welding

The TIG welders of LONGEVITY were created for both professional welders and people who do welding as a hobby. LONGEVITY company provides a full line of TIG welders that have AC and DC welding capabilities and thus the welders are allowed to weld various exotic metals, including aluminum. Thanks to the TIGWELD and MICROTIG series by LONGEVITY, the commercial welders can control the welds with different welding options including pulse welding. The TIG welders of LONGEVITY feature 110v and 220v capabilities and have various models including AUTO-VOLTAGE for global usage.

LONGEVITY TIG Welders

Why choose a TIG welder over other welding methods?

We offer a full of line of TIG Welding equipment for the Do-it-Yourself, Professional, and Industrial industries. LONGEVITY features two main line of TIG welding machines, the MICROTIG and the TIGWELD series models. The MICROTIG model is a small version of the a portable ACDC TIG Welder, while the TIGWELD series is a more professional line of TIG welding equipment. In the TIGWELD line, we feature the DX models which are analog with Pulse and AC/DC capability. In the EX models, we feature full digital TIG controls with Pulse and AC/DC capability. The TIGWELD line ranges from 160amps to 700amps for heavy industrial applications.

How do I select the right TIG Welder?

Selecting the right TIG welder can be a challenge. Here are some helpful tips we recommend when deciding on the right welder.

1. Will you weld aluminum? If yes, you will need to get a TIG welder with AC capability.

2. Do you need a welder with 110v capability? If yes, we have several models included in our TIGWELD SX line that will suite your needs.

3. How thick do you need to weld? Are you doing sheet metal or thicker materials?

4. What type of welding will you be doing? Fabrication? Production? Hobby? Industrial? LONGEVITY offers solutions for each of these categories!
