Schumacher 120V Welder User Manual


 
INTRODUCTION
DESCRIPTION
Your new plasma arc cutter has been designed to cut any electrically conductive material in
applications such as maintenance shops, service stations, van conversion shops, auto restoration and
salvage operations, etc.
On steel, all models can cut thicknesses of less than 26 gauge but the 120V model can cut up to 5/16”
inch steel, and the 230V model can cut up to 3/8” inch steel.
Your plasma arc cutter comes complete and ready to cut. All you need to provide is a clean, dry, oil
free compressed air supply.
The system is based on a modern DC inverter power supply. This special technology allows for the
construction of compact lightweight unit with high performance. Infinite power adjustment, high
efficiency and reduced power consumption make it an excellent tool.

POWER REQUIREMENTS
This Plasma Cutter is designed to operate on a properly grounded power source fused with a
minimum 20 amp fuse or circuit breaker. If you modify the power cord in any way, you will void the
manufacturer’s warranty. It is recommended that a qualified electrician verify the actual voltage at the
receptacle into which the welder will be plugged and confirm that the receptacle is properly fused and
grounded. The use of the proper circuit size can eliminate nuisance circuit breaker tripping while
welding.
DO NOT OPERATE THIS UNIT if the actual power source voltage is less than 100 volts AC or greater
than 125 volts AC (120) volt models); less than 198 volts AC or greater than 240 volts AC (230 volt
models). Contact a qualified electrician if this problem exists. Improper performance and/or damage to
the welder will result if operated on inadequate or excessive power.
