These collets are compatible with Weldcraft WP9 and WP20 series TIG torch models, making it a reliable replacement part or spare for fabrication workshops and trade professionals. Accurate electrode alignment is critical for arc stability, weld consistency and overall weld quality - making high-quality collets essential for professional welding performance.
BetterWeld offers five popular collet sizes, allowing welders to select the correct diameter to match their tungsten electrode and application requirements. Each size is suitable for different material thicknesses, amperage ranges and weld precision needs.
Sold in convenient packs of 5 - ideal for regular use or stocking up.
Available Sizes & Typical Applications
.020″ (0.5mm):
Ultra-fine tungsten size for micro TIG welding, thin sheet metals, precision electronics, jewellery work and delicate fabrication where very low amperage control is required.
.040″ (1.0mm):
Ideal for thin stainless steel, aluminium sheet, light fabrication and detailed TIG work requiring excellent arc control and low heat input.
1/16″ (1.6mm):
A versatile all-round size suitable for light-to-medium fabrication, automotive repairs, stainless steel work and general workshop TIG welding.
5/64″ (2.0mm):
Commonly used for medium-thickness materials, structural components and higher amperage applications where increased heat input and penetration are required.
3/32″ (2.4mm):
Best suited for heavier sections, fabrication work, thicker plate materials and sustained higher amperage welding.
