What is included with welder, I see nothing in the picture or in the description.

Torch number 17, ground cable, foot pedal, regulator/flowmeter, 110 220 adapter, are all included. Pictures are going to be updated to include everything. Sorry for the inconvenience, we are aware. Thank you for your question

I am a paraplegic, so foot pedal no good. Need a hand button and water cooling?

Hi Rich, thanks for your interest in the Weldpro AC DC TIG welder. This machine does come with a hand control button and even nicer, it has upslope and downslope features which allow for a kind of variable control amperage just by using the button and the slope features, but it is an air/gas-cooled unit, not water cooled. Water cooling usually doesn't become an issue until you start getting up toward 200 amps and over. However if you're not welding very thick metals the air-cooled units are usually all that's needed. You can always give us a call, the tech support number is listed on our site Weldpro com where we can discuss your needs and machine usage in more detail.

What is the minimum welding ticknnes and max? Thanks

Hi and thanks for your interest in Weldpro equipment. Your question is a very difficult one to put an exact number to especially when talking about very thin metal. So much of successfully welding very thin metal has to do with experience and technique. You can weld extremely thin metal with a variable amperage TIG welder if you are experienced in doing so. Additionally having features like this weldpro AC DC Tig such as pulse helps even more in welding thin metals I can't give you a number because again it is a matter of experience and technique while using the advanced features available with this machine along with other techniques such as heat sinks. Also remember while welding extremely thin metal you don't necessarily need filler rod. I've welding 2 razor blades together easily with this machine. On the other hand it's a little bit easier to put a number on thicker metal. I would say quarter inch would be no problem, but even heavier metal can be welded if you consider beveling and multipass welding. TIG welding is a great way to multipass weld. And don't forget this machine has a very capable stick welding mode which when combined with beveling and multipass can very easily weld 1/2 inch metal or thicker if it's prepared properly. With all that said TIG welding is a more precise form of welding and usually isn't the first choice for long runs of extremely heavy metal and that is where the stick welding function of this machine comes in very handy

Can argon post flow be set?

Thanks for your interest in the AC DC Tig. Absolutely, the post flow is adjustable from 1 to 15 seconds. The full manual with all the settings is available at the weldpro com website
