Category Sourcing Overview
ArcFort Weld organizes TIG torch parts and consumables by component role, company-catalog torch-series reference and the fit evidence needed for repeat purchasing. Ceramic cups, collets, collet bodies, gas lenses, back caps, tungsten electrodes and torch-control parts should be reviewed as part of a complete TIG torch assembly. Buyers can build a structured RFQ for WP-9/WP-20, WP-17/WP-18/WP-26 or WP-27 series references, while final compatibility remains subject to the exact label, drawing, approved sample or complete component stack.
Parts & Selection
Similar-looking parts can use different dimensions, threads or assembly relationships. Use the product family as a sourcing reference, then confirm the exact item from evidence.
Directs shielding gas around the tungsten and weld area.
Buyer check: Record cup number, connection style, torch family and whether a standard body or gas lens is used.
Grips and centers the tungsten electrode inside the torch head.
Buyer check: Confirm tungsten diameter, collet length, torch series and matching collet body or gas lens.
Supports the collet and forms part of the shielding-gas path.
Buyer check: Confirm torch series, thread, tungsten size and the ceramic cup used with the assembly.
Uses an internal mesh arrangement to distribute shielding gas before it exits the cup.
Buyer check: Confirm gas-lens family, torch series, thread, tungsten bore and compatible cup arrangement.
Secures the rear torch-head assembly and accommodates the tungsten length.
Buyer check: Confirm rear thread, cap length, torch series and available working clearance.
Carries the TIG welding arc and must match the documented welding procedure.
Buyer check: State confirmed diameter, length, type or color reference and application requirement.
Provides a torch-mounted control input where the torch and machine configuration supports it.
Buyer check: Send the torch model, switch shape, connector or wiring reference and photos of both sides.
These company-catalog family names help organize an inquiry. They are not universal-fit claims; confirm the torch label, part reference, sample, drawing or approved component stack.
Torch body, Back caps, Collets, Collet bodies, Gas lenses, Ceramic cups, Handle or switch, Cable assembly
Confirm whether the torch is a 9 or 20 series reference, then send the complete torch label, cooling or cable arrangement, front-end stack and machine-side connection. Shared catalog component families do not prove interchangeability between every configuration.
Torch body, Back caps, Collets, Collet bodies, Gas lenses, Ceramic cups, Handle or switch, Cable or hose assembly
State the exact 17, 18 or 26 series reference and provide the complete torch view, front-end arrangement, tungsten reference, cable or hose termination and any visible part number. The catalog groups consumable families, but final fit still requires evidence from the requested torch.
Torch body, Collets, Gas lenses, Ceramic cups, Cable or hose assembly, Torch terminations
Send the complete 27 series torch label, cooling-line and termination photos, tungsten reference, cup or gas-lens arrangement and requested cable length. Approve the complete assembly or matched parts list before repeat ordering.
Buyer Guide
Use these checks to prepare a sourcing request. Confirmed drawings, samples and approved references remain the basis for final product matching.
Check torch series and cup size before selecting ceramic cups or gas lens parts.
Confirm collet and collet body dimensions for the required tungsten size.
Provide packaging and labeling requirements when preparing distributor programs.
Use the TIG parts identification guide to name each component and keep the removed front-end stack in assembly order.
TIG torch parts should be checked by torch series, cup number, tungsten size, model number or drawing. Compatibility can be confirmed by sample, drawing or model number before final quotation.
Small trial orders are accepted for standard TIG torch parts. Customized packing, private labels and mixed item cartons are reviewed according to quantity, product type and export packing requirements.
OEM packaging is available for TIG ceramic cups, collets, collet bodies, gas lenses and related TIG accessories when buyers provide packaging style, label artwork and order quantity.

Common TIG torch components include a ceramic cup, collet, collet body or gas lens, tungsten electrode, back cap, torch head, handle, switch and cable or hose assembly. The exact arrangement depends on the documented torch system.
Please send the exact torch series, complete-torch and label photos, front-end parts in removal order, documented tungsten diameter, cup number or visible reference, connection views and quantity so ArcFort Weld can review the requested item.
OEM packaging can be discussed after product details, quantity and artwork requirements are confirmed.
Buyers should confirm torch series, cup number, tungsten size, gas lens requirement and package quantity before sending an RFQ.
