    for welding in blind spots, like on top and against frame rails , use a small mirror

    Just in my opinion, it might be worth the extra effort to take the exhaust right off so you can weld 360* without missing a spot that will cause trouble down the road. Are you replacing the whole exhaust or just a end piece?

    FWIW if you ever need to weld on a car or truck again disconnect the battery first. The welding current can mess up the computer or even the alternator...

    Rene's Right!!

    Yeah,dont do what I did--weld a new tailpan on my van under the rear doors...then start it up and turn on the radio,and hear your 150 dollar 300 watt amplifier squeal like a stuck pig,and belch out a big cloud of smoke!:blush: :blush: --I'm suprised my 15 inch woofers didnt burst into flames!--I guess amps dont like arc welders--I have toasted an altenator and several bulbs by forgetting to dissconnect the battery too--:blush: --I swear I'm gettin senile already--its bad enough to do something stupid--but to do it more than once must mean brain damage has occurred...:doah: :doah: :screwy: :angry1:

    So all you have to do is disconnect the battery to weld?

    Remember to unhook your battery! Since you would have to hook up the ground for your mig.:blush: Also if you are welding near your gas tank shield it somehow from the sparks, and have a fire extinguisher nearby.
