I'm pretty sure it doesnt include a regulator. The tank itself may be pricey. I ended up paying 135 for my 80cu bottle w/gas. Colin if you need a regulator. I've got an extra one, but it has a fucked up working pressure gauge.

I guess my e-sarcasim sucks :-\

200 for the TIG, yeah. Then add in the cost of the regulator/bottle/gas, it's at LEAST another 100-150 dollar ass raping. Still worth it though ;)

you may want to wire another pot inline with the one on the machineand put the second pot in the pedal. that way 'flooring it' will give you the current that you preset via the machine.

that's how most pedals are setup, afaik :)

Re: Harbor freight TIG thread (with pictars yay!)
 

this setup works; i can't complain...

it shouldn't cost you $400 to get started w/ this pos; unless you have to buy the tank. Most places let you rent tanks for a very reasonable fee. I've not priced one here but back in tx i rented a 250cu tank for $10/mo and got it filled for $38 and some change

these are DC machines right? meaning they cant weld aluminium? im pretty new to how tig welding works but not doing it. what makes DC not be able to weld aluminium?

Re: Harbor freight TIG thread (with pictars yay!)
 

do u have any new pics of the welds using the pedal??

Re: Harbor freight TIG thread (with pictars yay!)
 

Please elaborate

Re: Harbor freight TIG thread (with pictars yay!)
 

So did this idea actually work ???

Re: Harbor freight TIG thread (with pictars yay!)
 

Frequency, The Molecular build up of Aluminum is much different then steal and the way it tends to break down is better complimented by the frequency from an AC current.

Re: Harbor freight TIG thread (with pictars yay!)
 

is it possible to weld aluminum with a machine like this though?
