ING-MMA18028 Inverter MMA welding machine

The INGCO ING-MMA18028 is an inverter stick (MMA) welder for home, farm and workshop use — light-to-medium steelwork. It delivers 15–180 A and runs 1.6–4.0 mm electrodes.

What it is good for

• Steel doors, gates, window protection bars, railings and stairs
• Light steel frames, sheds, canopies and steel furniture
• Maintenance and repair work in workshops and on farms

Electrodes and materials

• Takes 1.6–4.0 mm electrodes.
• Typical current for general-purpose E6013 electrodes: 2.5 mm ≈ 60–90 A · 3.2 mm ≈ 90–130 A · 4.0 mm ≈ 120–170 A. Exact ranges vary by brand and type — always use the range printed on the electrode packet.
• Mild and low-alloy steel — with general-purpose rutile electrodes (E6013) or low-hydrogen electrodes (E7018) for structural and load-bearing joints
• Stainless steel — with stainless electrodes (e.g. E308L)
• Cast iron repairs — with nickel cast-iron electrodes
• Aluminium and very thin sheet (below about 1.5 mm) are better done with TIG or MIG welding

Key specifications

• Output current: 15–180 A
• Duty cycle: 180A@45%
• No-load voltage: 89 V
• Electrode diameter: 1.6–4.0 mm

Duty cycle in practice

Duty cycle 180A@45%: measured over a 10-minute period, this means about 4.5 minutes of welding at 180 A, followed by about 5.5 minutes of cooling. At lower currents the machine can weld for longer. Staying within the duty cycle protects the machine and extends its life.

Power supply

Single-phase 220–240 V, 50/60 Hz — runs on a normal household supply. Avoid long, thin extension leads. Low or unstable mains voltage reduces the welding current available. If you use a generator, choose one with enough capacity and automatic voltage regulation (AVR).

Features

• IGBT inverter technology — lighter and more energy-efficient than a traditional transformer welder, with a stable DC arc
• Hot Start — a short current boost when the arc strikes, for easier starting
• Arc Force — raises the current when the arc gets too short, so the arc does not die out
• Anti-Stick — cuts the current if the electrode sticks, so it can be freed without damaging it

In the box (per INGCO)

• Electrode holder with cable
• Earth clamp with cable
• Wire brush
• Welding helmet

You will also need

• Welding electrodes
• Welding gloves and protective clothing

Always weld with a proper welding helmet, gloves and protective clothing, in a well-ventilated area.
