Home Improvement welding consumables that start easily and deliver consistent arcs make workshop jobs neater and faster. TEN-HIGH TIG Tungsten Electrodes WL20 suit welders who need dependable arc starting and longer tip life. Are these electrodes the right choice for routine TIG work in a busy garage or small fabrication shop?
⚡ At a Glance
- • Weld Quality: Stable, easy-to-start arc with controlled heat input for cleaner welds
- • Best for: Hobbyists and workshop professionals using TIG for light to medium fabrication
- • Not ideal for: High-overload industrial applications where electrodes face frequent excessive currents
Lanthanum-doped tungsten electrodes, 2% lanthanum composition, 2.4 mm diameter and 150 mm length. Designed for easy arc starting, low tip temperature and use with both DC and AC TIG welding.
Reliable arc starting – thanks to 2% lanthanum composition
Lanthanum acts as an active element in the tungsten, lowering the work function at the tip and stabilising electron emission. That produces predictable ignition and keeps the arc steady once struck.
Quicker, more consistent arc initiation reduces time spent re-striking and makes welding thin materials less nerve-racking. Expect fewer interruptions while setting up and running beads.
Lower tip temperature and longer life – with lanthanum-doped tungsten
The lanthanum blend reduces tip overheating and slows grain growth during use, maintaining a sharper electrode profile under normal currents. Lower tip temperature helps preserve electron emission properties.
Electrodes stay usable for longer between regrinds, cutting downtime and the need to replace tungsten as often. That matters for routine workshop workflows.
Versatile for DC and AC TIG – thanks to formulation and WL20 type
WL20 lanthanated tungsten performs well across current types because the lanthanum composition balances conductivity and stability for both polarities. The formulation sits close to 2% thoriated tungsten in conductivity.
Suitable for machines and tasks that alternate between DC and AC TIG settings, offering flexibility when switching between steel and aluminium work.
