\u26a1\ufe0f Tungsten electrodes are welding electrodes used for argon (TIG) welding. There are several types, which can be identified as follows:
\n\ud83d\udd34 Red (WT20)
\nUsed for welding general metals. Do not use with aluminum or magnesium.
\nThe tip must be sharpened before every use.
\nSuitable for Direct Current (DC) only.
\n\ud83d\udd35 Blue (WL20)
\nCan be used with Direct Current (DC) and Alternating Current (AC).
\nThe electrode tip should be sharpened before use.
\nSuitable for welding a wide range of metals such as stainless steel, silver, nickel alloys, titanium, and brass.
\n\u26aa\ufe0f Gray (WC20)
\nUsed with Direct Current (DC) and requires sharpening before use.
\nIdeal for low-current welding, thin materials, and automatic welding.
\nSuitable for metals such as steel, stainless steel, nickel alloys, and titanium.
\n\ud83d\udc9a Green (WP)
\nBest suited for aluminum welding.
\nMade of pure tungsten and should not be sharpened to a pointed tip when used for aluminum welding.
\n\ud83d\udc9b Gold (WL15)
\nUsed with Direct Current (DC).
\nThe key advantage of gold-tipped tungsten is that it is environmentally friendly and can replace red (WT20) tungsten electrodes.
\nHighly versatile\u2014suitable for welding steel, stainless steel, aluminum, and titanium.<\/p>\n
