We want you to take pride in operating our Tig160PDC as much pride as we have taken in making this product for you. PLEASE EXAMINE THE CARTON AND EQUIPMENT FOR DAMAGE IMMEDIATELY When this equipment is shipped, title passes to the purchaser upon receipt from the courier.
Introduction The R-Tech Tig160PDC is a member of our field acclaimed family of welding products. Premium features include:1. 2. 3. 4. 5. 6. Inverter power source – more efficient to operate, provides smoother weld characteristics.
Safety Precautions Read entire section before starting installation WARNING! Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input power at the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine to an earthed mains supply as per national recommended standards. Select suitable location Place the welder where clean cooling air can freely circulate in and out of the front & rear louver vents.
Electrical Installation WARNING! ELECTRIC SHOCK CAN KILL Machine grounding and High Frequency Interference Protection This welder must be grounded to earth. See national electrical codes fro proper grounding methods. The high frequency generator being similar to a radio transmitter may cause interference to radio, TV and other electronic equipment. These problems may be the result of radiated interference. Proper grounding methods can reduce or eliminate this.
Input Connections 7 Make sure the voltage, phase and frequency of input power is as specified on machine rating plate located at rear of machine. Have a qualified electrician provide suitable input power as per national electrical codes. Make sure machine is earthed / grounded. Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers smaller than recommended will result in ‘nuisance’ shut off from welder inrush currents even if welding at low amperages.
Connections for Tig160PDC Rear machine connections Fig 1 1. Mains input cable Fit required plug as per your electrical installation 2. On/Off Switch 3. Gas input connector Connect input gas hose ensuring connection is tight 4.
Connections for TIG (GTAW) Welding Fig 2 1. Negative power connector Connect Tig Torch Dinze to power connector by inserting and twisting until tight 2. Gas outlet Connect the torch gas hose 3. Positive power connector + Connect the earth lead to by inserting and twisting until tight and the earth clamp to work/bench 4. Torch control socket 2-Pin Connect torch control plug To avoid a High Frequency shock keep the Tig torch in good condition and replace if any of the insulation is damaged.
Connections for STICK MMA (SMAW) Welding Fig 3 1. Negative power connector Connect the earth lead to by inserting and twisting until tight and the earth clamp to work/bench. 2. Gas Outlet – NOT used in MMA mode 3. Positive power connector + Connect the electrode holder by inserting and twisting until tight 4.
Controls and settings Fig 4 1. Up slope Adjustment 0-5 seconds. The main welding current raises from minimum amperage to main current selected in time selected when weld started 2. Down slope Down-Slope adjustment 0-5 seconds. The main welding current decreases from main amperage to minimum amperage in time selected when weld finished 3. Main current control This adjusts the main welding current and is shown in L.E.D (Fig 4.9) when welding is in process. 4.
7. Pulse On/Off switch 12 This turns the pulse welding on and off. 8. 2/4 Way selector switch 2/4 Step trigger mode switch – tig welding can either be done in 2 or 4 step mode. When the trigger mode is in the 2 step position the following sequence will occur Press and hold the Tig torch switch to start sequence. The machine will open gas valve to start flow of shield gas, after a 0.
Press and hold the tig torch switch to start sequence. The machine will open gas valve to start flow of shield gas, after a 0.5 seconds pre-flow time to purge air from torch hose the welding output of machine will be turned on and the arc will be started. After the arc is started the output current will be at start (min) current This condition can be maintained as long as required.
Operating machine SAFETY PRECAUTIONS WARNING! ELECTRIC SHOCK CAN KILL Do not touch electrically live parts or electrode with skin or wet clothing. Insulate yourself from work and ground Always wear dry insulating gloves WARNING! FUMES AND GASES can be dangerous Keep your head out of fumes & gases produced from welding. Use ventilation or exhaust to remove fumes & gases from breathing zone and general area.
Welding in TIG mode – No Pulse 1. 2. 3. 4. 5. 6. 7. 8. Connect the Tig Torch to machine, connect earth lead to machine & work piece. Set the TIG/MMA switch to TIG Set Pulse Switch to Off position Select 2 or 4 way torch operation Connect Argon gas and set flow to approx 8-12 LPM Set Gas post flow to 3 x diameter of tungsten width Adjust Base current to desired welding current Press the Tig torch switch to start welding Welding in TIG mode – with Pulse 1. 2. 3. 4. 5. 6. 7. 8.
Welding in STICK MMA (SMAW) Mode 1. 2. 3. 4. 5. 6. Fit MMA electrode holder to machine Fit earth lead to machine and to work piece Select MMA on MMA/TIG switch Place electrode in holder Select desired welding base current Strike arc and weld WARNING! ELECTRIC SHOCK CAN KILL When machine is switched to MMA mode, output terminals are always live, take care and do not touch electrode and earth by person at same time, otherwise electric shock will occur.
Maintenance Routine and periodic maintenance WARNING! ELECTRIC SHOCK CAN KILL Turn the input power OFF at the mains switch & fuse box before working on this equipment. Have a qualified electrician install & service this equipment. Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment. Do not touch electrically live parts 1.
Tig welding problems • No output - Power light is not lit Check machine on/off switch is in the ‘on’ position Check Input power to machine Check plug wiring Check mains trip / fuses • No output - Fan runs - Power light is lit Check torch connections are secure and torch switch operation, try replacing tig torch.
• Poor weld penetration Check condition of earth lead and clamp and ensure clamp is connection via a clean area on work piece Check condition of TIG torch, try other TIG torch • Machine stuck on minimum amps when welding although higher amperage has been set Make sure machine has not been set to 4-way operation as when in this mode when you press torch switch you get minimum amps and when you let go of switch machine will go to maximum amps set. • Arc ‘Flutters’ when TIG welding 1.
4 Gas flow may be insufficient, increase gas flow, reduce tungsten stick out from ceramic • No HF when torch trigger pressed, no blue spark between HF points Examine and clean HF points with clean dry low pressure air line HF PCB faulty – Contact R-Tech for repair MMA Stick welding problems • Stick electrode ‘blasts off’ when arc is struck Welding current set to high, reduce amperage or use thicker electrode Contaminated electrodes or material • Electrode sticks in weld puddle Welding current is set
