With a powerful 4000A peak current, this machine is capable of welding steel sheets up to 2 + 2 mm thickness, making it ideal for body panel repair, reinforcement work, and structural spot welding. Its microprocessor-controlled fuzzy logic system automatically adjusts welding parameters based on material thickness, delivering consistent results with minimal setup. The T4000 supports both pulse and continuous welding modes, allowing flexibility for high-strength materials and stress-sensitive applications. An adjustable arm pressure system (40–120 kg range) ensures proper electrode contact, while the insulated handle and housing enhance operator safety. Designed for professional use, the unit operates on 220V single-phase power, features IP21 protection, and includes automatic thermal shutdown to prevent overheating. Compact yet powerful, this portable spot welder is built for workshops, garages, and industrial job sites where reliability and accuracy matter.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e4000A High Peak Welding Power: Delivers up to 4000A peak current, designed for strong and consistent spot welds on steel sheets up to 2 + 2 mm thickness (14–16 gauge).
