Question: this is 50 or 60 or 50/60 Hz???, and whar DC only means, it is not AC/DC right?
Document: Ordered the unit on ebay. Just needed a little Mig for the garage. I am a welder by trade. So far this little welder has proven itself. I have welded 3/8 with .030 ER70S and it has no problem penetrating. Tried it with some .035 stainless wire and it ran just fine. I compared thos to a Millermatic 210 that we have at work and it runs right with it. Although I believe the duty cycle on the Miller is higher.
every item i have received from amazon has been damaged a smidge due to shipping practices!!! my welder had a couple of broken items on it when i received it!! other than that the welder has been great!! the drive motor used to feed the wire has now went bad!!! ive only had the welder 1 mnth!!! the lack of care that UPS uses when shipping our products is rediculous!! !exspecially for the rates they charge!!!
Well I havent had a chance to use this welder yet but one thing I wanted to rant about is the specs. The manual shows the operating voltage/amps 240V 22amps the Hot Max Torches website shows the amps at 35 but the box that the mig welder was packed in says 44amps.Makes me wonder at what kind of product I just bought.....we will see......update to follow.
The unit showed up in a timely manner but when we got it out there was internal damage to the unit. There were no options to get replacement parts or exchange for another unit so we were out of a welder.we did return for a refund.
The machining on the cart left a little to be desired. I had to grind down the top shelf to fit it against the back properly. screw holes don't always line up. Best to put it together completely loose then tighten everything once all the screws are in place.
Shopped around for several months until I saw this welder on Amazon, after reading several reviews I was sold.Prime shipping made it very affordable, better yet after I purchased the welder I went back to Amazon and noticed that the price jumped another hundred bucks.I haven't had a chance to use the welder yet because I've got to pick up an Argon/CO2 bottle and some solid wire, hopefully soon I'll get to use it.
My husband and daughter in law love it, thank you so much it's awesome, it works great, and it was a great price
It wasn't moving at all. After fooling around with it for a few minutes I decided to unscrew the cover and have a look. I found that a negative lead running from the main capacitor was disconnected from the main board. It was cut too short so I couldn't just plug it back in. I had to add a section of wire to jump the gap. Weird problem but it worked and I haven't had any more problems with it.
Investigated the problem and found the common lead from the speed control pot was not inserted fully in the mother board plug.
I ordered a used - Like new version of this welder for $330 which was a great price. It arrived well packed and nothing was missing. After I put together the welding cart I took a good look at the welder. 2 of the screws that connect the yellow frame to the chassis were loose. It looked like all the screws had been loosened and tightened a few times.I plugged it in and it powered on fine.
Answer: no
