Thank you for selecting the R-Tech PROARC175 Inverter Arc Welder The PROARC175 has many benefits over traditional transformer arc welders, including infinite power control, anti stick and hot start technology to aid easy arc starting and the inverter power source provides smooth weld characteristics We want you to take pride in operating our PROARC175 as much pride as we have taken in making this product for you.
The R-Tech PROARC175 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 vents.
Machine grounding and Interference Protection This welder must be grounded to earth. See national electrical codes for proper grounding methods. Radiated interference can develop in the following ways 1. 2. 3. 4. Direct interference from welder power source Direct interference from the welding leads Direct interference radiated from feedback into power lines Interference from re-radiation by un-grounded metallic objects.
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 The PROARC175 Inverter Welder requires a 240V 18A 50/60Hz supply ( at 125 amps output it will draw 13A input, if used on a 13Amp plug you may get nuisance fuse blows when welding at maximum amperage). It comes with a 2 metre mains cable attached. Connect wires according to national coding.

Controls and Settings 1. Current Control Knob This selects the welding power and is shown in LED display (3) 2. Warning indicator light Lights RED when over-heat thermostat protection has occurred, due to over work or poor airflow. Fan will continue to run and once machine has cooled down light will go off and machine is ready to use. Note: This light will come on for 1-2 seconds when first turned on and then will go off once start up self test has finished. 3.
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.
Operating Machine MMA mode 1. 2. 3. 4. 5. Ensure machine is setup as previously stated Fit desired electrode size in electrode holder Switch on machine Select desired welding power Touch electrode on to workpiece and arc will start Operating Machine Lift Tig mode 1. 2. 3. 4. 5. 6. 7. 8.
Troubleshooting Service & repair should only be performed by R-Tech welding trained personnel. Unauthorised repairs performed on this equipment may result in danger or injury to the technician and machine operator and will invalidate your warranty.
Arc welding problems 1. Stick electrode ‘blasts off’ when arc is struck Welding current set too high, reduce welding current Materials are dirty – clean before welding 2. Excessive Splatter Long arc – get electrode closer to work Welding current too high, reduce welding current 3. Insufficient penetration Too fast welding speed, slow down travel speed Welding current set too low, increase welding power 4.
