Use of normal 20 amp household breakers may result in over current trips. If breaker trips occur, reduce the cutting current output until nui- sance trips stop.
To achieve the full 25 amp output capability of the machine with 115 VAC input, remove the 15 amp or 20 amp plug on the input cord and install a 30 amp or 50 amp plug designed for 115 VAC (NEMA style 5- 30P or

For use on engine drives, keep in mind the above input draw restrictions and the following precaution.
The
•The AC waveform peak voltage is below 400 volts*.
•The AC waveform frequency is between 45 and 65 Hz.
•The RMS voltage of the AC waveform is always greater than 208VAC *.
*for 115 VAC input divide these values in half
The following Lincoln engine drives meet these condi- tions when run in the high idle mode:
Ranger 200 & 250 engine drives Commander 300, 400, & 500 engine drives
Many engine drives do not meet these conditions (eg Miller Bobcats, etc). Operation of the

•If compressed air is being used, it is highly recom- mended that an inline prefilter be installed in the air supply line ahead of the air connection to the PRO- CUT’s coalescing filter. While the coalescing filter is used to remove small amounts of oil and water aerosol particles from the air supply line, the prefilter can be used to remove larger particulates before they reach the coalescing filter element.This will pro- long the life of the coalescing filter element by up to six times what it would be without the prefilter, and in turn, prolong the life of the
•A standard nominal 5 micron inline prefilter is recom- mended; however, for optimum performance,select a prefilter with a 3 micron absolute rating. If these fil- ter ratings are unavailable, anything with a rating less than, or equal to, 20 micron would be accept- able to use. In line filter elements will generally filter the air with little restriction to the airflow until the ele- ment is about 75 % contaminated. After this point, there will be a noticeable pressure drop in the line.Filter elements should be replaced when a pres- sure drop of
