See for yourself how good these inverter based welders are getting.
Note the longer duty cycle. He started with a Hobart Handler, which
doesn't have the duty cycle that the Chinese inverter does:
Well, I got a pretty good deal some years ago on a Lincoln Square Wave
TIG 300. It can do stick, but I HATE the smell and the fumes mess
up my nose and sinuses. So, I have pretty much sworn off ever doing
stick again, but still have the cable and handle if I need to.
This welder can do something like 250 A continuously for hours.
It is a transformer machine with some SCRs and electronic control.
So, I am not complaining, although it is quite a bit bigger than
an inverter machine. I have done steel, aluminum and copper with
it, and the only limitation is MY skill, not the welder's.

Stick welding has its place and more than likely always will. Tig is
handy for small stuff...but when it comes to rough welding or big iron
welding..it still has a very definate home. Mig comes closest..but you
need big wire and a big machine to come anywhere close to matching
stick.

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie

Also mig and tig is not suited for under water welding.
