Flux Core Welding For Beginners; Cheap Welders That Actually Work!

Learn welding cheap! A simple guide to help get you going welding with a simple gasless flux core welder. The entire process was done using a Century FC-90 welder and gasless flux core .035 wire (very similar to a Harbor Freight Tools Titanium Flux 125), all while plugged into a 50' 12g extension cord.
In this video I focus on welding thicker materials.
Next video out will be for thinner materials and exhaust tubing.
Following this will be testing and comparing our FC-90 to the HFT Flux 125
Following this will be testing Stainless Steel Self Shielding (flux core) wire.

I am a mechanic, not a welder. But I needed a welder to weld a washer onto a ford door so i could put a threaded insert in for a inner door handle. The titanium flux 125 was great i welded it 2 years ago my washer is still holding up.

Right on!

Very concise and helpful video.

Than you!

Another great video! Thank you for taking the time to make it. I learned a lot and I did not know about that soapstone for marking, I already ordered some. Was this video made with the new camera you had mentioned? I've made the mistake you spoke about, trying to loop the bead - with no success at all. Now I will concentrate on just a stringer bead. Thank you again, very much appreciated.

[@DeathTollRacing]

No problem! No, I don’t have a good welding camera. I wish I did.
Once you get good at the stringers, doing a pattern will be a lot easier. You then won’t understand why you had trouble with them before. It’s kinda funny how it works out.

[@BobWhite777]

Excellent video, thanks.

[@DeathTollRacing]

Glad you liked it!

Good video , did you ever try and run that little welder with a portable generator ? I have wanted to purchase one but I need it to run on a generator so I can repair stuff in the field .

[@DeathTollRacing]

No. But that’s a great idea for a short video. I have a tiny generator I could try it on.

[@TheWingnut58]

As long as the generator will provide the needed output that the welder requires they work very well.

[@TheWingnut58]

You have current flow backwards, (yes, DC negative for FC) DC flows FROM the negative TO the positive, not from positive to negative as you state in the beginning of the video....

[@DeathTollRacing]

You’re probably correct. For some reason though, if you watch the current in tig welding in slow motion (I highly recommend because it’s really cool), it is electrode positive, and it appears the current goes from tungsten to surface. Maybe that’s a refresh rate thing. idk. I should add, it’s ac if it aluminum.

@@DeathTollRacing 32+ years 100% x-ray and pressure vessel certification in MIG, IS and TIG. I agree, it's a fascinating process in many aspects.....it's also pretty cool to freak people out sending the arc from your TIG torch to your fingertips...lol
You mention that it's AC when welding Aluminum, generally speaking that's true in today's common practice, but has not always been the case. Look up "Heli-arc" and its beginnings....its where modern day TIG began....very interesting stuff. Most people, including many welders, don't know that Aluminum can indeed be welded with DC.
Didn't mean to "bust your chops", really well done other than my "nit-pick"....

@@TheWingnut58 lol. I learned tig on a heli-arc machine. An old linde machine that weighed as much as a car. 😂
