How to Build a Spot Welder
As a spot welder this combination unit will
join ferrous metals up to 3/32 in. thick.
It works
especially well on stainless steel due to low heat
and electrical conductivity of this metal. For
heavier work it is used as an arc welder.
A
carbon-arc torch may be plugged in and used for
brazing, silver soldering, aluminum welding and
welding thin sheet metal as well as heating metals
for bending.
The voltage booster can be used to
eliminate power-robbing voltage drop when portable
electric tools and equipment must be used
on a long extension cord. The voltage booster
requires no extra coils, only a switch and receptacle
connected into the circuit.
