Page 3: Electric Shock Can Kill
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. - Page 4 WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

Page 15: Constant Current Processes
CONSTANT CURRENT PROCESSES MANUAL ARC WELDING (STICK) The Invertec may be utilized as a manual DC arc welder with the electrode cable, work cable, and elec- trode holder being the only equipment required. AIR CARBON ARC CUTTING Air carbon arc cutting may be performed with the Invertec within its output rating using 5/32"... -
Page 16: Parallel Operation
OPERATION PARALLEL OPERATION The Invertec’s are operable in parallel. For best results, the currents of each machine should be rea- sonably well shared. As an example, with two machines set up in parallel for a 300 amp procedure, each machine should be set to deliver approximately 150 amps, not 200 amps from one and 100 amps from the other. -
