180A is a nice size. We sell both Lincoln and Miller, they are both fine. A new option is Forney. The Forney uses standard Tweco consumables and has the heavy duty wire drive like the industrial grade Lincoln machines.
I personally would not buy a Harbor Freight. If it needs repair you are SOL.



I guess there is a big difference between owning a business and being familiar with the product.

I have welded 3/8 plate with my little 110 machine and beat the crap out of it. I ended up tearing the plate but never broke the weld.

It was good enough for me to put together a goose neck trailer hitch plate for the bed of my truck. That hauled 18,000 lbs of steel from OKC to DFW.

Tell me again how bad a 110 VAC machine is.


I no doubt maxed my machine but with careful prep and proper use you can do quite a bit of work with them.


Well the Space Shuttle did pretty well on on the first 24 launches, but the that number 25 was a bummer. Big difference between what can be done and what should be done. twocents

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
