Tig or Mig?

and if your set up right all you do is hold it down.

incorrect.
you want to have some + and - to it, if you're flat footed, the machine is set to cold.

I've been debating the same question. I've been gas welding and I'm wondering how hard it is to make the jump from gas to TIG. Any thoughts?

Hey,
If you are competent at oxy/acetylene TIG is a piece of cake. Think of the TIG torch as your gas torch and both use rods. Except with the TIG you have a pedal to increase power, unlike oxy, too hot-backpedal, too cold-more pedal. Once you get comfortable with TIG everything else is just plane lame! I have TIG, MIG, Oxy, and use TIG for all my welding, MIG for tacking, and Oxy for heating/preheating. But then everything i weld is cold rolled steel, hot rolled stays out of the shop!

its not incorrect. thats like saying mig is always too cold. give and take is what i do also but flatfooting a properly set-up machine is common practice and i think it makes the learning curve a little easier, then you can start using your foot.
but we dont need to get into a pissing contest.

Im a novice at best and all I have TIG'd is aluminum, steel may be different. The pedal or in my case the finger control makes it easy. Running flat tends to push you along where as with control you control the pace and the puddle.

I agree with the above statement.

Adjust the amperage so when you mash the foot pedal it will output the max amperage for the size of metal you're welding. Start the weld mashing the pedal and back off when the metal heats up. One less variable to deal with.

then you might as well just scratch start or lift arc and do away with the remote altogther.
