S7 TIG & ARC Welder – Gas TIG with Argon and Stick Welding, 200A, Dual Voltage

3‑in‑1 welding versatility

The S7 TIG & ARC Welder packs gas TIG with argon shielding, MMA stick welding, and a pulse TIG mode into one portable machine. This combination supports a broad range of projects from fabricating frames and brackets to on‑site auto repairs. The Pulse TIG option adds refined heat control for thinner metals or delicate joints, helping you shape beads with confidence. Note that aluminum welding isn’t supported, so you can plan your projects around the metals this machine is optimized for.

Crystal clear control at a glance

A large LED display keeps essential settings visible from across a busy shop. The interface is designed for straightforward operation, helping you dial in current, arc force, and gas flow without guesswork. Hot Start assists ignition for smoother starts, and Auto Memory recalls your last setup after power cycles, letting you resume work quickly on repeat tasks.

• Up to 200 amps of output for a wide material range
• Auto sensing dual voltage automatically adapts to 110 V or 220 V outlets
• HF non touch start enables reliable arc ignition with minimal contamination
• Three welding modes plus a reserved foot pedal interface for enhanced control

Built for comfort and consistency

Engineered for longer welding sessions, the TIG & ARC Welder maintains stable current and effective cooling, supporting steadier beads and less fatigue. At about 4.6 kg, the unit is surprisingly portable, making it easier to move between projects or store in a compact workshop. The compact footprint does not compromise its capability, so you can tackle both small craft pieces and more substantial repairs with one versatile tool.

• Gas TIG mode delivers cleaner seams with argon shielding
• MMA arc welding handles thicker sections for repairs and fabrication
• Pulse TIG provides controlled heat input for thin or non ferrous metals

Important usage note

This TIG-200 3‑in‑1 Welder is not designed for aluminum welding. Gas is required for TIG mode; ARC welding does not use shielding gas. Please confirm your project requirements before purchasing.
