Q 1. What thickness of steel can the SIP 25287 spot weld?

A. The 25287 is rated for 1+1mm (mild steel) / 6+6mm ø. Maximum welding current is 3800A. It is designed for automotive body panel repairs, general sheet metal fabrication, and light industrial production.

Q 2. What power supply does the SIP 25287 require?

A. The 25287 requires a 230V / 16A supply. If you are unsure whether your supply is adequate, consult a qualified electrician before installation.

Q 3. Is the SIP 25287 suitable for sustained welding?

A. The 25287 is fitted with thermal overload protection that cuts output automatically if the machine exceeds its rated temperature. Welding at lower amperages extends the continuous run time available before a cool-down period is needed.

Q 4. What is supplied with the SIP 25287?

A. The 25287 is supplied with the accessories needed to start welding — check the product listing for the complete included items. Additional consumables for the 25287 are available at PartsForMachines.com.

Q 5. How heavy is the SIP 25287?

A. The 25287 weighs 120kg. It is intended as a fixed workshop machine. Adequate assistance should be available for initial positioning.

Q 6. What materials can the SIP 25287 weld?

A. The 25287 is primarily suited to mild steel.

Q 7. What warranty does the SIP 25287 carry?

A. The 25287 is covered by SIP's 2-Year Standard Silver Warranty, covering manufacturing defects under normal use conditions. Register the product with SIP at time of purchase to activate the warranty.

Q 8. Can the spot welder be used on galvanised steel?

A. Spot welding galvanised steel is possible but produces zinc fumes — adequate ventilation or fume extraction is essential. Zinc coatings also accelerate electrode wear, so check electrode condition regularly when welding zinc-coated materials.

Q 9. Can the SIP 25287 weld galvanised steel?

A. Yes, but with precautions. Zinc coating produces fumes during spot welding — adequate ventilation or fume extraction is essential. Zinc also accelerates electrode tip wear, so inspect tips more frequently when welding galvanised material. Test on scrap of the same gauge first to confirm the weld schedule.
