ING-MMA1305 Inverter MMA welding machine

The INGCO ING-MMA1305 is a compact inverter stick (MMA) welder for home repairs, DIY projects and light maintenance work. It delivers 10–130 A and runs 1.6–3.2 mm electrodes.

What it is good for

• Home and DIY repairs: gates, doors, window protection bars, shelves and small frames
• Repairs to garden and farm equipment and light steel structures
• Learning to weld and occasional use

Electrodes and materials

• Takes 1.6–3.2 mm electrodes. 3.2 mm electrodes run near the top of its 130 A range, so expect shorter welding time per duty cycle with them.
• Typical current for general-purpose E6013 electrodes: 2.5 mm ≈ 60–90 A · 3.2 mm ≈ 90–130 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: 10–130 A
• Duty cycle: 130A@40%
• No-load voltage: 85 V
• Electrode diameter: 1.6–3.2 mm

Duty cycle in practice

Duty cycle 130A@40%: measured over a 10-minute period, this means about 4 minutes of welding at 130 A, followed by about 6 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.
