SUNGOLDPOWER MIG 150A Flux Core Weldersungoldpower flux core welder

SUNGOLDPOWER 150A Flux Core welder comes with everything that can turn your every welding session into sunshines and rainbows. Wondering how? Affordable price point alone attracts novice welders and DIY fanatics like moths to a flame. However, it also brings durability and reliability to the table. This provides such a lethal combination that resisting it becomes really hard.

Like above mentioned models, this one also features flux core wiring but what gives it an edge over such rivals is the wide amperage range (80-150 amp) that it offers. This enables the machine to shoot the amount of current output adequate for finely welding non-ferrous metals, iron and mild steel.

What really allows welders to hold it in high esteem, regardless of being a low-end model, is the peace of mind that this brings to each welding session. Thanks to heat adjustment settings and built-in thermal protection, welders complete projects without any unpleasant interruption and accident.

Finally, 110V input allows it to run on standard household power which is a blessing for DIYers and handymen but a curse for workshop owners.


  • Pocket-friendly.
  • Durable and lightweight structure.
  • Adjustable amperage output allows for efficient welding of iron, mild steel and metals.
  • Safe to use.
  • Ideal for home use.


  • Single power input (110V) limits its functionality.
  • Incapable of MIG aluminum welding.
  • Cannot uphold itself against demanding welding.

This small multi-talented beast is the solution to all your welding problems because it is housing 4-in-1 welding techniques.

Whether its gasless MIG by use of flux-cored wire, MIG gas, Arc function or Lift Tig, the machine will not shy away from undertaking the challenge. However, you’ll have to insert argon gas and purchase a separate torch for using the TIG function.

It’s a 220V DC welder that also features IGBT inverter technology so you can be assured of its high efficiency while welding stainless steel and iron materials. When seeing so much potential and versatility one naturally expects the machine to be giant like both in strength and size.

It’s pretty lightweight and compact which if on one hand is quite surprising then on other hand is a source of joy. I said joy because the lighter weight will enable you to carry it to any work location without flexing muscles.

However, there are a few complaints regarding the truthfulness of this claim so it will be better to not stretch the unit to its limit and restrict it to 3/16” or thinner sheets. While some think of it to be a put off, we think it’s a blessing in disguise for beginners. Amateurs will practice lighter welds first to polish their craft.

The machine can hold 2 and 10 pound spools and can run like a gazelle on a 0.03” wire. Not only this but by dialing in the right setting it will deliver some really neat small welds. Speaking of small, the machine is small in size and lighter in weight which makes it a reliable companion for light-duty outdoor jobs or home projects. 120V input makes things convenient because finding a standard power source isn’t much of a challenge.
