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. 3.b. - Page 4 WELDING and CUTTING 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 materials from welding can easily go through small cracks and openings to adjacent areas.

3. Be sure the torch and work cable rubber cover- ings are free of cuts and cracks that allow high frequency leakage. Cables with high natural rub- ber content, such as Lincoln Stable-Arc resist high frequency leakage than neoprene and other synthetic rubber insulated cables. -
Page 13: 230V Input
230V INPUT The equipment is provided with a 230/115V cable, 6.6ft.(2m) in length with a 230V 6-50P attachment plug. The Invertec V205-T performs best when connected to 230VAC inputs. This input allows full output of the machine (200 amps). 115V INPUT A suitable 115V attachment plug must be installed on the power cord to use the V205-T with a 115V input supply. -

DC Electrode Positive Polarity. (Direct Current Reverse Polarity) (see Figure B.5) In this case, there is a continuous flow of electrons from the workpiece to the electrode. The reverse polarity is used for welding alloys covered with a layer of refractory oxide. With this polarity the electrode functions as anode and is subjected to a high degree of heat;... -
Page 24: Steel Tig Welding
STEEL TIG WELDING The TIG process is very effective for welding both car- bon steel and alloy steel, especially in applications requiring precision results. DC Electrode Negative Polarity is required. Since this process does not include the removal of impurities, proper cleaning and preparation of the edges is required. - Page 25 B-10 PROTECTIVE GAS Both argon and helium work when welding aluminum. Argon is preferred, due to its lower cost and consump- tion rate. This gas also tends to stabilize the arc, thus making it easy to operate. For some applications, however, the use of helium, or argon-helium blends, is recommended due to better weld penetration and faster travel speed.
