A few more tips for scratch start tig welding along with walking the cup, stick welding, and welding with a tiny welder.
Scratch start tig can be done using almost any old DC stick welder.
But there are also some very affordable inverter welders that also work very well and are much more portable.
I am trying one of those inverter units in this video so I needed to do some tig welding as well as some stick welding.

You had mentioned in the 1st video the Miller DC machine, and for AC a high frequency unit would be needed. I understand the benefits of keeping it to DC welding and avoiding AC on this type unit.
My question (not that I am going to do it) is why couldn’t the Miller be switch to AC, it would be at 60 cycles. Is it that and once the arc was started it would extinguish being at a low frequency?

Hi Jody, I really enjoy your videos, and I get a lot of great information from them. A friend of mine says that he gets as good penetration on ac with 7018 as he does on dc. I have a hard time believing this. Could you do a comparison video with an etch and polish video on this subject? Thanks again for doing these videos every week!
