Inverter welder Sherman MIG 351M/4R

The MIG 351M welder is a second‑generation unit built with IGBT inverter technology. It is designed for manual welding of steel and non‑ferrous metals in shielding gases (MIG/MAG) and with a covered electrode (MMA). It can also weld without gas using flux‑cored wire. With a Spoolgun torch, it supports wires wound on 100 mm reels.

The machine operates from a three‑phase 3x400 V power supply and features a professional four‑roll wire feeder with smoothly adjustable feed rate (3–18 m/min). For MIG/MAG, the welding voltage is continuously adjustable (16.5–31.5 V), while for MMA the welding current is adjustable up to 350 A. Inductance control helps when welding thin sheets, and the unit includes adjustable post‑flow gas delay and a 2T/4T trigger mode. Thermal protection safeguards against overload. It works with K‑200 (5 kg, ø200 mm) and K‑300 (15 kg, ø300 mm) wire spools. Open‑circuit voltage: 59 V. Duty cycle: 60% (MIG/MAG and MMA). Approximate weight: 75.75 kg.

Included equipment: 4 m TW‑36 MIG torch, electrode cable, work return cable with clamp, and a chipping hammer with wire brush.
