Buying Guide for Best TIG Welder for Aluminum 2021

Is your TIG machine the reason for lower quality works?

Good question!

Tungsten inert gas (TIG) welding is the primary method used to weld aluminum. Because the aluminum workpiece requires a lot of heat to get up to temperature but can hold that heat for a long time.

Current Control

A welding machine with current control is beneficial for keeping the aluminum workpiece from overheating, causing a burn through.

TIG welding may be applied to both thin aluminum sheeting and thicker aluminum plate. Because TIG welding requires a separate filler rod, the welder must choose a welding rod with an alloy as close to that of the workpieces as possible.

That’s the way to go!

Clean Sheets

No matter what type of welder is employed to fabricate aluminum, the workpieces have to be extremely clean before welding begins.

Aluminum oxide incorporates a much higher melting point than the base aluminum. Therefore any oxides that remain on the surface of the workpiece can result in oxide inclusions in the weld, reducing the overall strength and appearance of the weld.

Picking the good TIG welder for aluminum may be an incitement for you. It would be best if you did some analysis to discover the most efficient machine that money can buy. Certainly, for the best TIG welder on the market for your home or commercial use, this guide will help you to find your desire aluminum TIG welder.
