MIG/MAG welding power source BÖHLER TERRA NX 400 SMC 400 A + WU 430

MIG/MAG welding power source BÖHLER TERRA NX 400 SMC 400 A + WU 430 – USED

In addition to MIG/MAG, the power source also enables MMA welding with coated electrodes and TIG DC Lift. It is suitable for welding carbon steel, stainless steel and aluminium when using the appropriate welding wire, accessories and shielding gas.

The offered set is equipped with a BÖHLER WU 430 external water cooling unit with coolant and a transport trolley, creating a professional mobile workstation ready for the addition of a suitable water-cooled MIG/MAG torch.

Condition: used / second-hand product. The device may show normal signs of use consistent with previous operation. The visual condition of the specific unit corresponds to the product photographs.

Technical parameters of the welding power source

• Model: TERRA NX 400 SMC
• Type: professional inverter welding power source
• Welding methods: MIG/MAG, MMA, TIG DC Lift
• MIG/MAG: conventional welding
• Welding current range: 3–400 A
• Maximum welding current: 400 A
• Power supply: 3×400 V, 50/60 Hz
• Supply voltage according to manufacturer: 3×400 V ±15 %
• Max. input current I₁max: 30.1 A
• Effective input current I₁eff: 19 A
• Max. power input: approx. 20.9 kVA
• Recommended slow-blow fuse: 25 A
• Open-circuit voltage U₀: 61 V DC
• Efficiency: approx. 89 %
• Protection rating: IP23S
• Insulation class: H
• Power source dimensions: approx. 690 × 290 × 510 mm
• Weight of the power source alone: approx. 34 kg

MIG/MAG duty cycle at 40 °C

• 400 A – 40 %
• 360 A – 60 %
• 330 A – 100 %

At an ambient temperature of 25 °C, the manufacturer states that 400 A at a 100% duty cycle can be achieved.

The high duty cycle of 330 A at 100% / 40 °C makes this device a suitable power source for longer work cycles in professional production.

Integrated welding wire feeder

The TERRA NX 400 SMC has a welding wire feeder integrated directly into the welding power source.

• Feeding system: 4-roller
• Wire feed speed: approx. 0.5–22 m/min
• Solid welding wire: standard Ø 1.0–1.2 mm
• Optional solid wire range: Ø 0.6–1.6 mm
• Flux-cored wire: Ø 0.9–1.6 mm
• Aluminium wire: Ø 0.8–1.6 mm
• Spool diameter: Ø 200 / 300 mm

The 4-roller drive helps ensure smooth and stable welding wire feed, which is essential for professional MIG/MAG welding and when working with softer materials.

Welding methods and functions

• MIG/MAG
• MMA
• TIG DC Lift
• digital control of welding parameters
• graphic control panel
• digital display of welding parameters
• 4-roller wire feeder
• compatibility with Ø 200 / 300 mm spools
• compatibility with remote control
