8 customers mention "Heat transfer"4 positive4 negative

Customers have mixed opinions about the heat transfer. Some say it burns on 110 and 220V nicely, and melts 3/8th plates without issue. Others report that the rod gets cherry red and melted way too fast at 78 amps on the display, keeping going into thermal shutdown. They spark but don't weld, cuts out after 1-2 seconds, and still produce terrible welds.

"...At those amperages, overheating has not been an issue yet (no overheats so far)...." Read more

"The rod sticks to metal and that's all....I hardly get a strike of arc weld also the entire rod gets cherry red and melted way too fast at 78amps on..." Read more

Little, lightweight, affordable and customizable welder
The welder is very nice. It comes with a hand strap (not indicated in the product description, but it is included, see pictures attached). Everything seem sturdy and well build.The menu is very simple to understand and use. The basic setting (current setting) is easy to change, also it provide direct indication of the indicated rod diameter to use with the current setting which is handy. So far, I changed no other settings than the current, but it is always nice to know you can change them as needed.I do not understand what the metal piece that is provided is supposed to be used for. There is no screw on the welder to fix it, and the manual explains nothing about this part... It is a mystery.5 stars, very recommended!PS: Despite the display not being very visible in the pictures due to some reflection, the display is actually very readable.

    Bought it to try welding for fun. For the $110 CAD price tag, I figured I couldn't really go too wrong. Although I have a lot to learn, and my welding looks like leprosy, the actual machine works pretty well so far. I only used it on 110v under between 30 and 75 amps, since I only welded very thin metals, and burn through is an issue. At those amperages, overheating has not been an issue yet (no overheats so far).

    One minus I discovered, is that the white number display is pretty hard to read in bright environments, since the off color for the segmented display is also white. This means that segments that are turned off are hard to distinguish from segments that are turned on. I would think that a red, green, or blue segmented display would be easier to read.

    The welder actually has a few features, including arc force (0-100 also commonly called dig), shock protection (on or off), current (main setting), and hot start (on or off).

    When plugging it on a multimeter (sadly I don't have a meter that can read over 10 amps), the voltage read 80 volts. When enabling shock protection, the voltage dropped to 19 volts.

    Overall, nice little machine for the price. Time will tell if it lasts, but it already allowed me to fix a garden tool, and work on some small machine projects I have. Plus, it's very small and portable.

    Works surprisingly better than expected on 110v. but is really impressive on 220/30 or more amps, similar penatration to a conventional 600v machine. Worked so well at work, I bought another for home. Only problem with the one at work was the spring in the electrode clamp stopped springing, but no problem as I work in a spring factory.

    Wow this thing actually works very well, I had to just try it because a welder for under 100 bucks really. 110 volt 2 inch long bead on a 15 amp breaker on 220 full 3/32 rod. This is nearly as good as Millers 110/220 in fuction but not sure the longevity will be, but half box of rods it’s actually paid for itself already. Good purchase for the low cost

    For the price paid the welder works very well. I used it to weld my hitch that I custom built on 240v and it did very nice welds. I find that using 7018 rods it's a bit harder to start the arc (tends to stick) but once it starts the welds are awesome. I checked the output amperage and I was within 4 amps from what the panel was saying. Great welder for the price. I'm a happy customer.
