Used MIG welding machines for sale

Machine data (There may be errors in the information):

Here are the technical details I have gathered for these ESAB welding machine packages. Please note these are traditional, very robust industrial machines commonly used in demanding professional work.

1. ESAB LAW 400 + MEK 4S

This combination is a heavy-duty, step-adjustable MIG/MAG power source paired with a versatile wire feeder.

Power source (LAW 400):

• Type: Three-phase, transformer-based MIG/MAG power source.

• Welding output: Max. 400 A.

• Duty cycle (intermittent): Approximately 400 A / 35% or 280 A / 100%.

• Voltage steps: Stepped adjustment (typically 20–40 steps depending on year).

• Features: A reliable workhorse well suited for heavy workshop use.

Wire feeder (MEK 4S):

• Feed rolls: 4-roll drive (ensures steady feed with long torches and soft wires such as aluminium).

• Controls: Wire feed speed, burn-back time and often a start/creep function.

• Compatibility: Usually fitted with a Euro-style connector.

2. ESAB LAX 380 + MEK 4

The LAX series is known for excellent welding characteristics and is slightly more compact than the LAW series while still offering strong performance.

Power source (LAX 380):

• Type: Three-phase rectifier.

• Mains connection: 230/400 V (selectable).

• Welding output: Max. 380 A.

• Duty cycle: * 380 A / 35% load.

  • 280 A / 60% load.

  • 195 A / 100% continuous use.

• Voltage steps: 30 steps (3 control switches: 1 coarse, 10 fine adjustments).

• Weight: Approx. 143 kg (water-cooled model LAX 380W approx. 157 kg).

• Protection class: IP 23 (suitable for outdoor use).

Wire feeder (MEK 4):

• Feed rolls: 4-roll drive.

• Functions: The basic MEK 4 offers precise wire feeding control and is built to withstand heavy use.

Torch cables and earth/ground cables are missing.

The machines may have other defects.
