As soon as it warms up a little bit here in CT I'm going to tackle my first roll bar install.

Going to do an 8pt bar, chromoly and I have a couple of questions.

Can I tack things with a flux core mig and then go back over everything with the TIG or will the tack be too contaminated.

My TIG only has a foot pedal control that will be impossible to use while contorted in the car making welds. Is it possible to rig a simple on/off switch somehow. My TIG is a Syncrowave 180SD.
