When you're working near the limit with MIG you can pulse it rather
than applying continuous power, but that can result in a discontinuous
weld or poor penetration. Button welds (spot welds made with a MIG)
can be a useful technique if you don't need a continuous seam.

there's also the bitumen & coal dust trick to get 'continuous' welds.
