IGBT Inverter Technology

The intelligent IGBT inverter is one of the most beneficial features for you. It reduces energy loss and improves efficiency, which results in smoother arcs, less power waste, and more consistent welds. For your projects, that means more reliable startup behavior and better performance when you change settings.

IGBTs also contribute to a smaller, lighter design, so the portability claim isn’t just marketing—this technology helps make it possible.

Why this matters to your welding

You’ll notice fewer fluctuations in arc stability and a generally more responsive machine when you change wire feed speed or amps. If you’re working on thinner sheet metal or patchwork, that responsiveness helps prevent burn-through and makes it easier to control bead appearance.

3-in-1 Welding Modes: MIG, Lift TIG, Stick

Having multiple processes in one unit gives you flexibility. You can use:

• MIG (flux core) for quick, no-gas welding on mild steel—ideal for outdoor jobs or when you need portability.
• Lift TIG for cleaner, more precise welds, especially useful if you buy a torch and want to work thin stainless or steel with better aesthetics.
• Stick for outdoor repair, thicker steel, or rusty surfaces where flux-core or TIG might struggle.

Practical considerations

Remember that Lift TIG requires a separate torch purchase. If most of your work will be MIG flux core and stick, the included accessories will probably be sufficient. If you plan to TIG frequently, budget for a compatible lift TIG torch.

Portability and Build Quality

At 12.8 pounds, you can carry this welder without a dolly or cart. The handle is integrated and comfortable for short moves. The housing feels durable for hobby and light professional use, though it’s not built like a heavy industrial weld plant.

How you’ll use it

Because it’s compact, you can take it to a friend’s place, a remote job site, or simply move it around your garage. If your work frequently requires heavy duty continuous duty cycle performance (long, uninterrupted welds on very thick plates), you’ll need to watch for thermal cutoff and duty cycle limitations typical of compact inverter welders.

Safety Features and Protections

Safety is an important part of working confidently. This unit includes automatic voltage fluctuation compensation and protections against overcurrent and overload. That means if your input supply fluctuates, the machine compensates to keep the arc stable and protect internal components.

What this protects you from

The protections help prevent damage to the welder and reduce the chance of electrical faults that may create unsafe situations. Still, you must follow basic welding safety practices—proper PPE, ventilation, and secure grounding remain essential.

Ease of Use and Controls

The advanced digital display increases visibility and helps you quickly set parameters like wire feed speed and voltage. The synergistic control means the machine can help match wire feed speed to the selected voltage range, which is particularly useful if you’re getting started and still learning ideal settings.

Why beginners will appreciate it

You won’t have to guess as much about starting points for settings, and the clear display makes fine adjustments easier. Small welders often struggle with stable wire feeding; this model’s adjustable feed speed and digital feedback reduce that concern.

Performance in Real-World Welding

Here’s a practical look at how this machine performs across its three modes in everyday scenarios.

MIG Flux Core Performance

You’ll find flux-core MIG convenient for repairs, car panels, and structural touches where external gas isn’t an option. The built-in wire feed motor is adjustable and can produce reasonable bead appearance when tuned properly. For best results, use clean edges, correct wire diameter, and appropriate speed/voltage settings.

You’ll also want to pay attention to travel angle and speed: with flux core, a slightly faster travel speed and a slight push angle can minimize slag and produce more uniform beads.

Lift TIG Performance

If you add a lift TIG torch, you can expect decent TIG performance for thin material and finish work. Lift TIG won’t be as elegant as a dedicated AC/DC TIG unit, but for DC TIG tasks on mild steel, it’s competent.

Because Lift TIG uses a touch-start method rather than high-frequency start, you’ll need to touch the tungsten briefly and lift to initiate the arc — practice will quickly improve your technique.

Stick Welding Performance

Stick mode provides strong penetration and is forgiving on rusty or dirty material. You’ll appreciate the stick mode for farm repairs, structural maintenance, or when working in environments with wind or contaminants that make MIG impractical.

Stick setup is straightforward: select current and stick electrode size appropriate for material thickness, maintain consistent arc length, and keep a stable stance for even beads.

Thickness & Materials Capability

This machine is best for thin to medium-thickness mild steel applications—think sheet metal repair, light structural work, hobby fabrication, and maintenance. You can weld thicker sections in short passes, but heavy plate and industrial fabrication may push the limits of a 135A unit.

It handles mild steel well with both flux core and stick rods. If you plan to weld stainless or aluminum frequently, remember that TIG capability is limited to DC lift TIG and you’ll need a separate TIG torch; aluminum TIG typically requires AC capability, which this machine does not offer unless specified otherwise.

Setup and Getting Started

Setting up your new DEKO involves a few clear steps.

• Place the unit on a stable surface with good ventilation. Avoid confined spaces that trap heat.
• Connect to a proper 220V outlet with adequate amperage and a dedicated circuit to avoid voltage drops.
• Install the wire spool and feed it through the guide to the welding gun according to the manual.
• Tension the drive roller appropriately—too loose and the wire will slip; too tight and the wire may deform.
• Start with conservative settings on the digital display and increase wire feed speed and voltage gradually until you achieve a stable arc and desired penetration.

Recommended starter settings (approximate)

These are guideline starting points. Exact settings depend on wire diameter, feed quality, and joint geometry.

Material & Thickness	Process	Wire Diameter	Approx Wire Feed Speed	Voltage / Amperage
Mild steel, 18 ga (0.8 mm)	Flux-core MIG	0.030″	Low	Low voltage
Mild steel, 16–14 ga (1.2 mm)	Flux-core MIG	0.035″	Medium-low	Medium voltage
Mild steel, 1/8″ (3 mm)	Flux-core MIG	0.035″	Medium	Medium-high voltage
Mild steel, 1/4″ (6 mm)	Stick (6013/7018)	N/A	N/A	Higher amperage near max
Thin sheet stainless (TIG)	Lift TIG (with torch)	N/A	N/A	Lower amps for thin sections

Always test on scrap before committing to your workpiece and adjust gradually.

Maintenance and Care

You’ll prolong the life of your welder by following a few maintenance steps:

• Keep vents and fan areas clear of dust and metal particles to prevent overheating.
• Check consumables (contact tips, nozzles, drive rollers) and replace as they wear.
• Inspect cables and connectors for damage or loose connections before each use.
• Store in a dry, temperature-stable environment to prevent humidity-related corrosion.
• Clean the wire feed path periodically to avoid jams or inconsistent feeding.

When to seek repair

If you notice inconsistent arc behavior not corrected by settings, burning smells, or erratic display errors, stop using the unit and troubleshoot. Overcurrent or overload protections will sometimes trip—allow the unit to cool and reset, and check for blocked airflow or excessive duty cycle usage. If issues persist, contact customer support or a qualified technician.
