Used MIG welding machines for sale

Machine details (information may contain errors):

Below are the technical details I have collected for these ESAB welding packages. Please note these are conventional, very durable industrial machines commonly used in demanding professional environments.

1. ESAB LAW 400 + MEK 4S

This combination is a robust MIG/MAG power source with stepped control paired with a versatile wire-feed unit.

Power source (LAW 400):

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

• Welding current: Max. 400 A.

• Duty cycle (Intermittence): Approx. 400 A / 35% or 280 A / 100%.

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

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

Wire-feed unit (MEK 4S):

• Drive wheels: 4-wheel drive (ensures even feed with long torches and soft wires such as aluminium).

• Controls: Wire feed speed, burn-back time and often crater/start functions.

• Compatibility: Typically fitted with a Euro 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 remaining high-performance.

Power source (LAX 380):

• Type: Three-phase rectifier.

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

• Welding current: 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-feed unit (MEK 4):

• Drive wheels: 4-wheel drive.

• Functions: The basic MEK 4 provides precise wire feeding control and is built for heavy use.

Torch and earth cables are missing.

Machines may have other defects.
