Its a great starter machine and i use it still as my primary machine when doing fab work for customers. I also have some welding tutorials on the channel.If you want to check them out. And On behalf of the "buddy"(s) who usually gets asked for stuff , thank you😂

My brother got one of these with flux core wire. I borrowed it to fix 6 metal folding chairs which had broken supports. This was especially impressive as the metal on these chairs is paper thin. I think I only burned through once, and even then I was able to tap weld and fill in that hole fairly easily. These chairs with cushions cost about $45 in Walmart. So I saved almost 300 with this one repair job, that took maybe 30 minutes. Next time I have a project I'll just buy this welder as it will nearly pay for itself by then.

I have the titanium unlimited 200 and I love it. Great little inverter box for the money. I think mine was around $600 when i bought mine a few years ago.

I bought the titanium 200 about 3 years ago. Never had a problem yet. The only problem is that the LED display is hard to see in bright sun light when I'm welding outside.

Good review. I Just picked up the Titanium unlimited 200 at Harbor Freight about a month ago for $559. I waited almost a year and a half for the sale price I wanted, 30% off the regular $799 price. I've only tried it on 120v flux core and 3/32" 6013 stick @70amps. I use 6013's with an old buzz box so that is what I had on hand. Welder was working pretty hard to maintain arc after first inch or so. I think it started out ok because of the hot start setting.

I haven't had issues on 115v when I need to use it. I definitely prefer 240v just for the extera power and single pass abilities but if your running flux core and DCEN its no slouch on 115v! Ive welded 3/16 diamond plate with no problems. And once you finally do get a 240v plug its like a hole new machine

I have run it off my Predator Inverter geni with no issues. I am told you need to run an inverter geni to get clean power. A non inverter geni will fry the boards. Thats what I am told anyway. Thanks for watching.

You used two contact tips in 2 years. You obviously don’t use that welder much. Theres days were I can burn threw 2 in an hour and I dip my nozzle in gears every other pass

I have a 170 and I just upgraded to a 200 myself and I love em! I use it for everything! Even building my demolition derby cars! I do agree, the knobs sensitivity is frustrating but we work around it

I like my titanium unlimited 200 only down side is MiG wire stick out we found has to be much further than half a inch needs to be more like a couple inches for it to not get porosity build up plugging up the tip. It would’ve been nice to have the pedal control for tig maybe that’s the trade off getting that versus the Vulcan multiprocessor you can get the pedal tig bought separately

I hate this welding machine

The 170 is definitely sick. Mine happened to have issues. Idk if it was the motor or something on the circuit board butnit would always stop. Sometimes it would run good for a while but it would always stop at some point even after letting it rest for a good while. Sometimes I’d leave it alone for days and it stop 2 mins after firing it up. I always have bad luck with stuff like this. But I’m thinking of buying another hopefully it goes well this time
