Test the duty cycle and maximum output amperage and you’ll find it’s just a thin-walled welder. Shame on you Tim for not checking on the REAL criteria that defines a welder (bought two of your subscriptions because I thought you were a reputable influencer). Truth be told, this welder CANNOT DELIVER! I have since relighted my 170 as a thin-walled tubing (Only) welder. Tim! Please don’t sell-out.

The only issue is the amount of time you can weld continuously. Then it will overheat. Pay attention to the length of time. On the inside of the cover you will find the time limits. I bought mine and it runs very well. Made a canopy out of pipe. Made a metal pipe rack out of spare pipe in a few hours. Tools I used. A cordless grinder with cutoff wheels and flap wheel pads. Tape measure. Soap stone. 1 1/4 pipe . Welding hood. Ear muffs to cut the cutting metal apart and clear grinding hood. Leather apron. Leather shoes. I ran out of my big spool of wire and bought a new roll. The new roll welds better. Coped the pipe ends to join each pipe to make the joints.

you can push or pull with mig depending on your preference or welding instructions. more penetration when you pull. I have this same machine and it is awesome

I own the titanium 170 and I was trained at 18 and now I'm 60 I was a welder for that long and this is a great welding machine is awesome working with them

Great video I commented on the 205 when you did the review on that Because I have one and think it’s great I also have the titanium 170 And I think for the money it’s the ideal mig welder For the price Yes red white or blue welder guys with scoff at them both Until they try them Then they always admit how good they weld and it’s pretty much the same with as you mentioned most of the new inverter welders There are a lot of good machines out there for great prices Are they going to be in a pro weld shop and hold up all day everyday ? Probobly not the first choice But for a welder at home or on the road It’s just tuff to beat these two brands Thanks for the Video Dave

I have the titanium 170 and I've used one 5 lb spool of aluminum before my machine broke I've had it for a couple years inside my apartment it's like new but it doesn't work I had the same problem with the wire continuing to run now when I pull the trigger there's not enough power to turn my spool gun and if I put the other torch on for the flux wire it does the same thing so logic would say it's the relay on the PCB board I'm going to contact the manufacturer or I suppose I should say Titanium because they don't actually manufacture this it's made in China with what I believe is just another case of planned obsolescence I will do a follow-up on my experience I'm possibly going to make a video about my experience and if I am forced to repair it I will make a video on that repair

@chadrides914i love it! i used it for 110 flux recently and was actually kinda impressed even tho i HATE flux

DecosGarageFeb 13, 2026 Positive

yes it still works! i dont use it daily anymore but it still works great

yes... until it over loads and trips it. some breakers are slower to go then others. and the longer the cord you use the sooner it trips it, but in a pinch it will run it. at reduced amperage it will run on a 15amp breaker drop down to .030 wire and it will run a good duty cycle under 15 amp breaker (in my experience) but start bumping up the out put you will find it trip the 15

super good have run many hundred pounds of hardwire .035 hardwire thru it mostly under co2 some mix gas

@Stogie1984titanium is really solid man. I had mine for 2 years before something on it started acting up. But I’m upset cause people say they’ve had theirs longer. I’m convinced I had a lemon cause it started being weird like a week after purchase, just never bothered me enough til it truly gave up. I still love it tho. Gonna get another. I’ve got My ESAB rogue 180, but I want a portable MIG/flux. I ran several 10 Ib & 2 Ib spools through that baby. Burned just as good as alot of Lincoln’s and millers I’ve used of that same capacity.
