  1. Hayden

    This machine is awesome, especially for the price you pay. The main selling point to me of this machine was that it didn’t have tapped controls.

    My only complaint is that the torch is very short, and I don’t think it’s going to hold up to the abuse that I will put it through. Sometimes I smell plastic cooking from the torch.

    All in all, with the extras this machine comes with, it makes up for the short torch.

    Nice little welder for home use. Set up was easy and I was welding in no time.

    Excellent starter machine hope that I could buy or upgrade soon

    Great product. Right out of the box it comes with everything you need to start welding. Even some flux cores wire. I purchased a 2 pound roll of .035 and used that for some heavier duty welding. Puts out great beads. My only wish was that I should have bought the next product up to add the TIG process as well.

    Couldn’t be more happy with the delivery especially during the covid 19 situation. The machine welds nicely, and I’m impressed with the accessories it came with.

    Purchased the mig 155Gsv to replace my old century 120 mig. So far so good it seems to burn hot & has no problem welding thicker steel. Controls are easy to use & the extra voltage control is a plus makes dialing it in a breeze. Also their customer service is speedy & very knowledgeable. Would recommend to a friend.

    I ordered this unit to be a small portable unit that I can use when I have to do things away from the shop. It is a great size and has good features especially for the price. The only things that I would say could be improved upon are the torch lead is too short and The unit does not appear to be able to accept large 10lb wire spools. I would recommend this to anyone who wants a small unit that can do multiple processes!

    This is my first welder. The quality is great and the company did everything they said they would. Thanks WeldPro

  9. Garrett Harmon

    This is an amazing little welder , it works well , great for teaching my son. I wish I would have found this sooner!

  10. Cody J.

    Pretty neat little welder for the money. It’s does everything I need to around my shop. My only complaint if I had to make one is the Mig gun cable being a little short but with a good extension cord and cart it solves the issue.

  11. Raymond M.

    So far product performs as well as or better than advertised…after order was completed it arrived in 9 days,in good condition and will rate whole process 95%…100% if a tracking # was available.

    Mig torch cable could be a little longer. All in all, the welder seems excellent. Love the dual polarity and the convenience of the pigtail. Great little welder.

    I just ordered my weldor , no said what welding rods can be used for this machine, 6013,6010,6012, 1/8 or 3/16 0r is it the little rods, not sure you can burn 7018 because it a reverse a reverse polarity.

  16. Arthur Taft

    have not opened the box yet.

  17. Andrew

    Hey ken, I’ve used 7018 1/8th rods and it burns amazing, 1/4 inch vertical groove welds on 3/8th steel, great welder for the price, duty cycle is high also

    Best customer service I have received during Covid-19 situation. very quick to respond. Have any questions they will answer them very promptly. Welder is great. I’m not a newbie nor an expert when it comes to welding this machine makes it really simple and has all the juice i need for my personal garage. Only con i have is the mig gun is not detachable. If damaged will have to purchase replacement specifically for this unit. If stick welding the gun and its cable have to be coiled up and stored by the machine. This for me is not a big deal because i will be using the mig gun on most if not all my jobs. Thank you guys for the great product and service.

    After owning a harbor freight flux core welder, this is a vast improvement over that turd. I am by no means a pro welder but after a few minutes I can get decent looking welds with good penetration.

    Great price

  23. micheal keefe


    replaced a flux core only welder with this to get away from the splatter.
    super happy with everything except the- seems- extra short wire lead. please weld pro offer a longer replacement and make me and I’m sure many others happy happy happy

  24. Ricardo R.

    Easy to setup and weld out of the box.

  25. Carl Howell

    I didn’t purchase this welder for myself. I purchased it for my son who lives in Texas. He received it, rounded up all the things needed to do the first side job that he had, went to work and after 9.5 hours of fabricating and welding he completed the job. the welder did exactly what he needed done and it ran well. Lots of power and now he had another side job lined up for this coming weekend. I say all went well. Thank you for your quick delivery of this fine piece of equipment.

    Best customer service ever.
    I had a few issues with my machine. I called Tech support Nick Campbell and he was prompt, responsive , & extremely helpful to my issues. Not only are these great little machines ( I also own the 200 ACDC TIG) , when buying a machine – tech support and customer service can tip the scale. It’s an intangible that is hard to factor into the decision of what to buy. The company stands behind its machines and will make things right if you have any problems.
