Q 1. What is the SIP 15071 ceramic cup used for?

A. The ceramic gas cup directs shielding gas around the tungsten and weld pool during TIG welding, protecting both from atmospheric contamination. The cup size and profile affect gas coverage area and torch access to tight joints.

Q 2. What size is the SIP 15071 ceramic cup?

A. The cup bore is 16mm, fitting TIG torch collet bodies of the same size. Always match ceramic cup bore to your tungsten diameter — oversized cups reduce gas velocity and coverage quality.

Q 3. Which TIG torches does this ceramic cup fit?

A. The SIP 15071 fits SIP TIG torch bodies using the corresponding collet body size. Check the torch series (SR9, SR17, SR26) and tungsten diameter against the cup specification before ordering.

Q 4. When should I replace a TIG ceramic cup?

A. Replace immediately if cracked — even hairline cracks cause gas turbulence and porosity in the weld. Also replace when the cup is heavily spattered (restricting gas flow) or chipped at the exit. Ceramic is brittle — handle with care during changeovers.

Q 5. Can a cracked ceramic cup cause weld defects?

A. Yes — a cracked cup disrupts the laminar gas flow around the weld pool, allowing atmospheric oxygen and nitrogen to contaminate the weld. This causes porosity and weld discolouration, particularly visible on stainless steel and titanium.

Q 6. What is a gas lens and should I use one?

A. A gas lens is a collet body with a fine mesh screen that creates more uniform, laminar gas flow from the cup. Gas lens setups provide better gas coverage, allowing longer tungsten extension and improved access to joints. They are particularly beneficial for stainless, aluminium, and exotic alloys.

Q 7. What sizes of ceramic cups are available?

A. Ceramic cups are sized by bore diameter to match tungsten and collet body sizes — 1.0mm, 1.6mm, 2.4mm, and 3.2mm are the standard TIG sizes. Additional cup lengths (short, standard, long) are available for different access requirements. The full range is in the TIG Consumables section.

Q 8. Can I use a Pyrex (glass) cup instead of ceramic?

A. Yes — Pyrex/glass gas cups provide full visibility of the weld zone and are useful for precise positioning work. They are more fragile than ceramic and are most commonly used for TIG welding of visible stainless or aluminium work where weld placement accuracy is critical.

Q 9. What safety equipment do I need for welding?

A. At minimum you need a welding helmet or headshield (auto-darkening recommended), leather welding gauntlets, a fire-resistant apron or jacket, and steel-toe boots. For enclosed spaces, a fume extractor or respirator is essential. A welding curtain or screen protects bystanders from UV flash. Keep a fire extinguisher accessible.

Q 10. Is the SIP 15071 in stock for fast delivery?

A. Yes — UK stocked for fast despatch. Check availability at PartsForMachines.com. Orders placed before the daily cut-off are dispatched same or next working day. Check the product page for current delivery estimates.
