Mig welding upside down
Need to fit in a chassis rail - can to to top and side.
but other than raising the chassis, is there any way I can weld the underside?
It is worth while trying to rig up some guide or just bite the bullet, get the trolley jack, axle stands, wheel rmaps and hoist to lift as high as
poss.

Welding upsideown is fine! Its not as easy as doing it the right way up though!
Just watch out for molten sparks,.... they HURT when they drop down your sleeve!

wear a proper welders hat as work like this can cause sparks down your neck. Keep the wire speed & heat down and welding upsides down is not to
hard. Its always better to turn it over though or lift one side of the car up.
Like I said the worst bit is the sparks come from a new direction. Be very careful too about setting fire to your clothes (sparks fall on the same
place), I've done that twice, both times working upsides down, fortunately a friend was there keeping a look out to put me out!

thanks for the concern for my health. 
as some one who has had a molten blob of metal drop into an ear, you needn't worry about not taking protection

was it all the way in or just the lobe.
I used to know a guy who had a hole in his earlobe where a bit of weld spatter fell into his lobe but because he was under the vehicle he couldnt get
it out and it burned through

Confused but excited.

Jeez! And I though having a blob lodge behind my watch was bad.
I knew it would be bad because I could smell it but it didn't hurt. 
Tell them about the bent treacle edges!

nope - inside the ear - I could hear it sizzling away
doesn't seem to have done any damage as I was concerned about it burningtorugh the membrane!!
whenever grinding or welding, I use earplugs - bits of moistened tissue.

I had a fizzer in the ear too - I was inside an Escort rear wheel arch. No damage to the ear but it made me jump and bash my head - moral is wear a
full-face helmet!

use lacky bands on your overalls around the wrists otherwise this can happen.
1. see red hot spark disappear down sleeve.
2. pull arm down until it impacts ground and clamps red hot spark against elbow.
3. move arm away quickly from red hot spark
4. push red hot tip of mig welder into the palm of the other hand.

FWIW when i did an engine swap i just welded 3 sides and left the bottom unwelded. Worked fine whilst i owned it. Think the bloke i sold it to welded
it when he rebuilt it all.

I have done the blob in ear - unbelievably painful! It did burn through the ear drum. I went to causualty and said my ear drum was perforated - the
nurse said "how do you know?" I demonstrated by blowing air out of my ear!!
Took only a few weeks to heal over but blew out again when scuba diving.......
Wear a hat!
Gas welding upside down is a lot easier than mig.

I've had this a couple of times when welding underneath a car, it's an extremely unpleasant situation to put it mildly!
A full face welding mask and an old towel to wrap around my neck has saved me from any further upper body welding burns, but still doesn't stop
the occasional "doh!" moment when I pick up something that has just been welded.

Are earmuffs the answer here?
1) Think hard about what you are going to be doing and what could go wrong.
2) Assess the risk - eliminate the worst risks to yourself. (and others!)
3) Wear protection where you can't eliminate the hazards.
