The Edon TB400 is a DC inverter MMA/ARC welding machine designed for medium to heavy welding applications. It operates from a 220–240 V single-phase supply, making it suitable for workshops, garages, construction sites, metal shops, and maintenance setups where mains power is available.

With a welding current range up to ~180 A, the TB400 can handle thicker metals and larger electrode sizes than lower-rated models like TB250 and TB300. Its IGBT inverter technology provides a stable arc, better energy efficiency, and lighter, more portable construction than traditional transformer welders — giving welders more control and less fatigue during extended work sessions.

It is ideal for welding structural steel, heavy gauge sheet and plate, farm equipment repairs, fabrication projects, and industrial maintenance. The added arc-force, anti-stick, and hot start features improve arc striking and reduce sticking, even under challenging welding conditions.

Common Applications

✔ Structural steel welding

✔ Heavy-gauge fabrication

✔ Farm and machinery repair

✔ Workshop metalwork

✔ Construction site welding

✔ Maintenance and industrial repairs

Edon Welding Machine — TB400 (Inverter MMA/ARC Welder)

General Features

  • Model: Edon TB400

  • Welding Process: MMA / ARC (Manual Metal Arc) welding — stick welding with coated electrodes

  • Technology: DC Inverter with IGBT — efficient, stable arc, lighter weight, and better energy conversion than transformer units

  • Input Voltage: ~220–240 V AC, Single-Phase (standard mains supply)

  • Protection: IP21S (protection against light water drip and dust under normal use)

  • Cooling: Built-in forced air fan for effective heat dissipation

  • Portable: Carry handle and compact size for on-site work

Electrical & Welding Performance

SpecificationTB400 Typical Value
Input Power Capacity~6.5–7.5 kVA (approx.)
Input Current~28–35 A
No-Load Voltage~60–70 V
Welding Current Range20 A – 180 A
Maximum Output Current~400 A peak capability
Duty Cycle~60 % @ 40 °C (recommended operating duty)
Efficiency~85 %+
Power Factor~0.7–0.75

⚙️ Duty Cycle ~60 % @ 40 °C means the machine can run ~6 minutes out of every 10 at rated current without overheating.

Electrode & Welding Info

  • Electrode Diameter: Typically 2.5 mm – 4.0 mm

  • Suitable Electrode Types: Standard MMA/DC stick electrodes for mild steel, structural steels, stainless steel (with appropriate electrodes)

  • Materials Welded: Carbon steel, structural steel, cast steel, some stainless steels (use correct electrode chemistry)

Built-In Functions & Advantages

✔ IGBT Inverter Technology

Delivers a stable welding arc, improved energy efficiency, and reduced slag/spatter.

✔ Adjustable Welding Current

Smooth control across the output range lets you tailor heat and penetration for different thicknesses.

✔ Hot Start / Anti-Stick / Arc Force

Common inverter-welder functions that help strike the arc easier, prevent electrode sticking, and stabilize the arc.

✔ Thermal & Overload Protection

Built-in protections reduce the risk of damage from overheating or unsafe load conditions.

✔ Fan-Cooled Design

Ensures continuous operation up to the rated duty cycle by keeping internal components cool.

Mechanical & Build

  • Dimensions: ~350 × 180 × 240 mm (approx; varies by market)

  • Weight: ~6–8 kg (approx)

  • Housing: Durable metal/plastic combo with ventilation ports

  • Handle: Carry handle for easy movement between jobs
