Soz for being dumb.. but i have almost completed full chassis and I have ran into a problem. While attempting to fully weld chassis, i am finding it VERY difficult to weld the hard access joints, for example O1 and O2 to O3 where the access is limited.
How do i weld these when my mig nossle can hardly get into the area???????

If it's in a tight corner the shield gas will be confined round the weld so the nozzle should be okay a bit further away. You can build the weld up from just out of the angle and build it onto the other tube with some practise, then turn the power up and run over it to tidy it up.

yours, Pete.
