⚠️ Usage Notes

Power Safety: Use the matching plug according to local power standards; ensure stable power input to avoid equipment damage.

Welding Material: Confirm the welding material type (aluminum pole/nickel sheet) and switch the corresponding mode in advance.

Welding Pen Care: The S-75B welding pen is for special use only; avoid non-professional modification. Replace the welding needle regularly to ensure welding quality.

Operation Environment: Work in a dry and ventilated place; keep away from flammable and explosive materials to prevent safety hazards.

Parameter Adjustment: Adjust preloading delay and pulse time based on the thickness of the welded material for optimal results.
