This is cheaper than their Black Friday prices for 2017, 2016 , 2015, 2014

I don't recall ever seeing a coupon that makes it lower either.

How does this compare to the Flux 125 Welder for $8 more?

Dunno how good this is, i got the "MIG 130 Flux Core Welder" on eBay and It's been great. Read reviews on Amazon where it's $100 and get it from eBay where it's $80. Free shipping no tax of course.

I believe these are AC not DC. Garbage.

Interesting. I was curious and looked it up:
Welding Output = 60 ~ 120 A, AC

Didn't realize they made AC welders.

One specific industry for AC stick welding is in shipbuilding, particularly when welding into a corner and arc blow becomes a problem. Another area is maintenance and repair.

"Those are the guys that will use AC stick welding more than anyone as a primary option," Beardsley says. "Maintenance and repair welding requires work on machines that are magnetized. Also, maintenance and repair work can involve a lot of rusty weld areas, where you don't want high penetration."

A switch to AC polarity requires a power supply and electrode both designed to run AC. Again, because any production type of process is probably going to be DC, "if you want an AC capability, you have to specify that," Beardsley says. AC/DC power supplies are available but on the higher end models.

How well do you think this would work for a a flex pipe on a car? Would rather gift this to my friend than pay meineke a $100+ for a 10 minute job

Is there a good harbor freight welder that you do recommend? I don't want to have to use gas. I just want to do it as a hobby and make random things.

I've had one for about 4 years. I use it for all kinds of automotive stuff, and is perfect for exhaust work. Seat brackets, general fabrication, etc. Works great as long as your not expecting a beautiful weld. Im also still learning, but it gets the job done.

I'm not sure about these being garbage, I have one of these and for the times I've used, it worked great.

won't make pretty welds, but perfectly functional welds.

Do a Google search and there are tons of videos on how to mod these to DC. It will work fine for thin metals but you will get very pitted, ugly welds.
