if your planning to do alot of welding on the bike or any vehicle for that matter, a tig setup would definitly not be a bad investment.

I know Miller makes a few smaller "buzzboxes" that are great for little projects, and if your wanting to get into aluminum welding def talk to a rep at a good weld shop, not every machine can weld aluminum.

if you do get a tig machine, get some scrap material and practice practice practice.... first walking the cup, then freehanding, all the while learning to feed the wire in. it will take a bit of time to get proficient at it but def worth the investment!!!! much cleaner than the squirt gun. lol

 

Electrical components grounded to the frame do not complete the circuit unless the key is 'on'.

The welder sends a current through the frame when the arc sparks, however, the energy is concentrated at the location of the arc. You will not damage any electrical components. most sensitive electrical components have separate grounding cables and are shielded properly from high voltage lines.

 

yeah i would agree w/ Fearless, dont make welding on the frame that keeps you in a straight line your first project w/ aluminum. it can be a lot trickier than carbon or stainless, and dummygun aluminum welding is really only good for bigger projects when you want to lay down some serious wire (boat frames or whatever); go TIG or go home. if i could say something to disagree though, i wouldnt walk the cup with aluminum, youll save money on cups.
