I have used many different kinds and learned with Oxygen acetylene and coat hangers when I was about 12.
Stick welder AC/DC225 Lincoln was my first stick welder to try and I was 19 and built a trailer with it.
I have had the Ac225 and have a few of them now and a AC/DC one and a few mig welders.
Lincoln mig 100 and 135 weld exactly the same.
I got a HF Titanium 170 Mig and it welds as good as a Lincoln 225 mig I used often.
Just yesterday i got to try a HF (harbor Freight) Titanium 225 stick inverter welder.

I was super impressed.
3 of us were welding brackets on steel plates and rebar to make shooting targets.
This little welder that weighs less than a car battery has great penetration on 120 volt which is what we used.
It is 120/240 volt welder and output in DC.
Super smooth and beginning the weld there is minimal rod sticking like you may experience with AC.
For such a light and inexpensive welder it really did well.
Now I have tried to build top rails on a trailer with the little Lincoln mig 100 and it just does not penetrate 3/16" steel good enough to make it stay together for the abuse I toss at it.
I have always used the Big 225 Lincoln for that.
Using that little Titanium 225 yesterday I believe it would not have any issues with trailer building.
I would buy it before a Lincoln 100 or 135 mig if I had planned on welding 3/16"
I really like my Titanium 170 mig.
HF has stepped up their game.
