Installation And Operator Instructions - Lincoln Electric POWER WAVE 345M C Bedienungsanleitung

CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.

The PW345M C is a complete semiautomatic multi-
process DC arc welding machine offering CV and CC
DC welding. It is rated for 350Amps at 35% and
300amps at 60% duty cycle. The standard machine is
equipped to weld CC-Stick, CC-GTAW, CV-
FCAW,synergic and non-synergic CV-GMAW /
synergicGMAW-P processes. The digital microcomputer
based control system allows easy and accurate
adjustment of weld parameters through the multi-
process panel located on the front of the machine. The
PW345M C, is equipped according to the choosen
version with a 3-pin connector to allow operation of a
