WELD-PAK 90i MIG

The WELD-PAK® 90i MIG is a compact, lightweight inverter‑based wire feed welder designed for 120 V input. Ideal for DIY, hobbyist and light‑to‑medium welding projects, it supports both MIG (GMAW) and flux‑cored (FCAW) processes.

Key Features

• Plug‑and‑play 120 V operation – weld anywhere power is available
• Supports flux‑cored up to 1/4 in. and MIG up to 3/16 in. material thickness
• Metal case protects against the elements
• Portable design with shoulder strap and lightweight inverter chassis
• Simple two‑knob control for wire speed and voltage
• Infinite voltage adjustment for fine‑tuning weld characteristics
• Smooth inverter operation for consistent weld quality
