A. The SIP 02973 is rated for 1 - 1.2mm wire diameter. Always match liner bore to wire — an undersized liner causes feed resistance and burn-back; an oversized bore allows the wire to coil inside and jam.
A. The SIP 02973 is a 4m liner. Ensure the liner length matches or slightly exceeds your torch lead length — a liner that is too short leaves an unlined section that causes wire feed resistance near the contact tip.
A. Replace the liner when wire feed hesitates despite clean drive rolls and correct spool tension, when you see swarf (fine metal particles) coming from the nozzle, or when the liner is kinked beyond straightening. A worn liner is the single most common hidden cause of erratic MIG performance.
A. Yes — the SIP 02973 is a steel spiral liner, the standard type for mild steel and stainless steel MIG wire. For aluminium wire, use a PTFE (Teflon) liner instead — aluminium is too soft for steel liners.
A. Remove the contact tip and gas nozzle. Disconnect the torch from the machine. Pull the old liner from the gun (nozzle) end. Feed the new SIP 02973 liner from the machine end through to the torch body. Trim at the nozzle end — leave approximately 5mm proud of the contact tip holder. Refit the contact tip and nozzle. Feed wire through to check smooth travel before welding.
A. The SIP 02973 liner is designed for SIP torch bodies in the specified diameter range. Liners are not fully universal — check the liner outer diameter matches your torch liner guide tube before ordering. Most MIG torch liners fit a standard 4mm OD liner guide, but always verify.
A. Yes — a contaminated or worn liner creates intermittent wire feed resistance that produces current spikes and arc instability. These symptoms are often mistaken for machine faults or incorrect voltage settings. Always check the liner before adjusting machine parameters.
A. Premature liner wear is caused by: using wire that is too large for the liner bore, running excess drive roll pressure that scores the wire surface and creates swarf, kinking the torch lead, or using non-matched wire types (steel liner with aluminium wire). Keep the torch lead coiled loosely and avoid tight bends.
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.
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.
