NOTE: Lincoln Electric assumes no responsibility for liabilities resulting from board level troubleshooting. PC Board
repairs will invalidate your factory warranty. Individual Printed Circuit Board Components are not avail-
able from Lincoln Electric. This information is provided for reference only. Lincoln Electric discourages
board level troubleshooting and repair since it may compromise the quality of the design and may result in
danger to the Machine Operator or Technician. Improper PC board repairs could result in damage to the
machine.
