Electrodes, Wire, Rods and Gas

These charts identify and size what you weld with. Decode a stick electrode classification, find the filler rod for a base metal, identify a tungsten by tip color, and check wire, cup and gas cylinder sizes.

Tools in this group

• MIG Gas Flow Rate Chart and Calculator — Pick the metal and transfer mode to see the shielding gas flow in CFH and L/min, and how long an argon cylinder lasts at that flow.
• MIG Wire Size Chart and Calculator — See every MIG wire diameter in inches and mm, and work out how much wire is on a spool and how long it lasts at your wire feed speed.
• TIG Cup Size Chart — Convert TIG cup numbers to inside diameters and see how fast the shielding gas leaves the cup at your flow rate.
• TIG Filler Rod Chart — Pick a base metal to see the usual TIG filler rod, decode a rod classification, or count rods per pound for your rod size.
• Tungsten Electrode Chart — Identify a TIG tungsten by its tip color, or find the current range for a tungsten diameter and the size for your amperage.
• Welding Gas Bottle Size Chart — Look up argon, CO2, oxygen and acetylene cylinder sizes and see how long a bottle lasts at your flow rate.
• Welding Rod Chart (Electrode Decoder) — Type a stick electrode classification such as E7018 to read its tensile strength, welding positions, coating and current, or browse the chart.
