The Lincoln Electric – Powertec 355C Pro MIG Welder (230/400 V, 3-Phase, 30–350 A) is part of the Powertec® PRO range, engineered for superior arc characteristics and minimal spatter with Argon mix or 100% CO₂ shielding gas.
Its rugged four-roll drive system, powered by a 90 W motor, uses large-diameter drive rolls and an electronic feedback system to maintain stable wire feed speed even with long cables. The synergic control mode simplifies setup by allowing operators to set only the voltage, with the machine automatically adjusting wire feed speed to match.
The welder offers precise voltage selection via two switches (3-step and 10-step), enabling fine-tuned control. Bright digital volt and ammeters provide clear monitoring of welding parameters. Practical design features include a lower cylinder platform for easier gas bottle loading, a push/pull bar, and lifting eyes for improved maneuverability in workshops.
With a current range of 30–350 A, rated output of 350 A at 40% duty cycle and 220 A at 100% duty cycle (at 40°C), the Powertec 355C Pro is suitable for a wide range of material thicknesses.
