A-2 INST ALLA TION V205-T AC/DC TIG A-2 MACHINE GROUNDING AND HIGH FRE- QUENCY INTERFERENCE PROTECTION The Capacitor Discharge Circuit used in the high fre- quency generator, may cause many radio, TV and electronic equipment interference problems. These problems may be the result of radiated interference.
A-3 INST ALLA TION V205-T AC/DC TIG A-3 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 ® better resist high frequency leakage than neoprene and other synthetic rubber insulated cables.
A-4 INST ALLA TION V205-T AC/DC TIG A-4 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 AC/DC performs best when con- nected to 230VAC inputs. This input allows full output of the machine (200 amps).
A-5 INST ALLA TION V205-T AC/DC TIG A-5 This unit does not include a TIG torch, but one may be purchased separately. The accessories section of this manual lists a number of Lincoln Electric TIG torches, and TIG Torch Starter Packs that are recommended for use with this machine; however, any similar TIG torch can be used.
A-6 INST ALLA TION V205-T AC/DC TIG A-6 REMOTE CONTROL CONNECTION A remote control receptacle is provided on the lower center case front of the welder for connecting a remote control to the machine. Refer to the Optional Accessories section of this manual for available remote controls.
B-1 OPERA TION V205-T AC/DC TIG B-1 Read and understand this entire section before operating your machine. SAFETY INSTRUCTIONS ELECTRIC SHOCK can kill. • Do not touch electrically live parts such as output terminals, electrode or internal wiring. • Insulate yourself from the work and ground.
B-2 OPERA TION B-2 REAR CONTROL P ANEL (FIGURE B.1) • I1: Off/On switch turns on the electric power to the welder. It has two positions, "O" off, and "I" on.
B-3 OPERA TION B-3 V205-T AC/DC TIG 1 . Input Voltage warning light green LED - Indicates that the machine is on and input voltage is within acceptable range. 2. Thermal Shutdown Light (yellow LED) - Indicates thermal over load or output disabled for incorrect supply voltage.
B-4 OPERA TION B-4 5. Output / Parameter Adjust Knob - Allows you to continuously adjust the current both in TIG and in Stick welding. Allows you to change the value, shown on "Digital Display Item 6", of the parameter selected with "Setup/Parameter select button Item 4".
B-5 OPERA TION B-5 3. Press and hold the TIG torch trigger when the main part of the weld is complete. The machine will now decrease the output current at a controlled rate, or downslope time, until the Finish current is reached. Both the Downslope Time and the Finish Current are presettable.
B-6 OPERA TION B-6 SET UP MENU Many additional parameters can be modified via the Set Up Menu. To access the Set Up Menu: • Position the ON/OFF switch to OFF “ 0 ” .
B-7 OPERA TION B-7 WELDING POLARITY DC Electrode Negative Polarity (Direct Current Straight Polarity) (see FIGURE B.4) While Welding, there is a continuous flow of electrons from the electrode to the workpiece.
A.C.- PULSED TIG B-8 OPERA TION B-8 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.
1. The AC wave balance can be set to a higher per- centage electrode negative which minimizes tung- sten heating and erosion. 2. The AC frequency can be varied to "focus" the arc. Increasing the AC frequency above 60Hz will nar- row the cone shape arc from the tungsten ’ s tip.
B-10 OPERA TION B-10 PROTECTIVE GAS Both argon and helium work when welding aluminum. Argon is preferred, due to its lower cost and consump- tion rate.
B-11 OPERA TION B-11 DC TIG WELDING QUICK ST ART UP ELECTRIC SHOCK can kill. • Have an electrician install and service this equipment. • Turn the input power off at the fuse box, dis- connect or unplug supply lines and allow machine to sit for five minutes minimum to allow the power capacitors to discharge before working inside this equipment.
