thru the frame . Garanteed to break off the legs .

There's two power supplies inside . In parallel they

weld , in series they Plasma cut .

The 180 amps is run thru relays ! Those contacts cant

GUNNER'S PRAYER:
"God grant me the serenity to accept the people
that don't need to get shot, the courage to shoot
the people that need shooting and the wisdom to know the difference.
And if need be, the skill to get it done before I have to reload."
