About this item

The Dekuch 140A MIG Welder is a versatile 4-in-1 multi-process welding machine supporting MIG (gas/gasless), Lift TIG, and Stick ARC welding. With dual voltage 110V/220V, it is perfect for home workshops, DIY projects, and light fabrication. Features synergic control for easy amperage and wire speed adjustment, overload protection, and the ability to weld mild steel up to 4mm thick.

Key Selling Points

  • Multi-Functional Welding: 4 modes – MMA, Lift TIG, flux MIG, gas MIG.
  • User-Friendly Synergic Control: Automatically adjusts voltage and wire feed speed.
  • Gas or Gasless: Use flux core wire (gasless) or solid wire with gas.
  • Lift TIG and ARC: Lift TIG for thin workpieces (1-4mm), ARC with E6013 rods.
  • Powerful and Safe: 140A capacity, overload and overheating protection.
  • Dual Voltage: Works on 110V and 220V outlets.

Specifications

  • Input Voltage: 110V/230V
  • Rated Input Capacity: 4.5KVA
  • No-load Voltage: 65V
  • Output Current Range: MIG 30-140A, MMA 20-120A, TIG 20-160A
  • Duty Cycle: 30% at 40°C
  • Wire Diameter: 0.6/0.8/0.9/1.0mm
  • Electrode Diameter: 1.6-4.0mm
  • Protection: IP21S
  • Insulation Class: H

Package Includes

  • 10' MIG gun
  • 10' electrode holder
  • 10' earth clamp
  • Additional .030" & .035" contact tips
  • 110V/220V adapter
  • Hammer & brush
  • Gas hose
  • 1kg 0.8mm flux cored wire
  • User manual

How to Use

1. Select welding mode (MIG, TIG, Stick). 2. Set amperage using synergic control. 3. For MIG, connect gas if using solid wire, or use flux core wire for gasless. 4. Adjust wire feed speed if needed. 5. Weld with appropriate technique. 6. After use, turn off and disconnect power.

Suitable For

Mild steel, stainless steel, alloy steel, carbon steel up to 4mm thick. Suitable for thin workpieces with Lift TIG.

Caution Notes

Always wear proper welding helmet and protective gear. Ensure adequate ventilation. Do not exceed duty cycle. Use correct wire and gas for material. Keep away from flammable materials.
