RANGER 250
The Ranger 250 can deliver from 40 to 250 amps of
constant current for DC stick welding or from 20 to 250
amps of constant voltage current for DC semiautomat-
ic wire feed welding. DC TIG welding is possible
across the entire range from 20 to maximum rated out-
put. Output can be adjusted by setting the OUTPUT
control dial and the ARC control dial on the output con-
trol panel to the settings that are best for your selected
welding process.
NOTE: An unstable or unsatisfactory welding arc can
result if welding cables are too long or are coiled on the
machine when welding.
Installation section. Straighten out coiled cables
before welding.
