Thank you for selecting the R-Tech INV160 Portable Inverter Mig Welder. The INV160 has many benefits over traditional transformer mig welders, including infinite power control, adjustable arc force and a compact wire feed mechanism to provide very smooth wire feed and weld characteristics We want you to take pride in operating our INV160, as much pride as we have taken in making this product for you.
Introduction The R-Tech INV160 is a member of our field acclaimed family of welding products. Premium features include:1. Inverter power source – more efficient to operate, provides smoother weld characteristics than traditional welders 2. Infinite welding voltage to allow fine tuning of weld characteristics 3. Adjustable arc force – controls splatter – ideal for automotive work 4. Digital amp & volt meters 5. Euro type torch fittings for easy torch fitment/replacement 6.
Amperage range 0.8mm wire Suitable Wire Diameter Gross Weight Insulation 50-160 AMPS 0.6mm 0.8mm 18 KG Class F 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.
Read and follow the ‘Electric Shock Warnings’ in the safety section if welding must be performed under electrically hazardous conditions such as welding in wet areas or water on the work piece. 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.
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. Failure to follow these instructions can cause immediate failure within the welder and void machines warranty. Turn the input power OFF at the mains switch & fuse box before working on this equipment. Have a qualified electrician install & service this mig welding equipment.
Connections for MIG INV160 Setup machine as per two diagrams below: Fig 1 Fig 2 1. Earth / Workpiece connector Connect the earth lead (negative - ) to this connector. Insert male connector into socket and twist clockwise until tight. Secure other end of earth lead to Workpiece via the earth clamp. 2. Euro torch connector Connect Euro type Mig torch to euro torch connector, align torch connector to machine connector and then turn retaining ring clockwise to secure.
Controls and Settings Fig 3 1. Welding Voltage This adjusts the welding voltage (weld power) from 0 to 10. Adjust knob for power output required by job, preset welding voltage is shown in LED (Fig3.4) 2. Wire Speed This adjusts the wire feed speed from 0-100% Adjust the wire speed to suit welding voltage (Fig3.1) and job requirements When adjusting the wire feed speed a value is shown in the amperage LED (Fig3.
This allows the machine to be calibrated to BS if required by your company 5. Amperage LED Display This shows the preset wire feed speed when no welding is being carried out When welding this shows the actual welding amperage This allows the machine to be calibrated to BS if required by your company 6. Warning LED This warning light will come on under these situations Duty cycle of machine has been exceeded, the machine will stop working and the fan will continue to run until machine has cooled down.
Wire Spool Fitment 1. Wire reel retainer Push and twist in, to retain wire roll adaptor onto wire reel 2. Roller tensioner Do not over tighten wire feed pressure roller as this can cause premature motor and roller failure. Correct way to adjust tensioner is to slacken off pressure so that mig welding wire does not feed, slowly adjust pressure until wire feeds smoothly, you should be able to stop wire feeding by holding wire and it should slip on rollers.
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 Once you have set machine up as per above instructions. 1. Select welding voltage (power) required on front panel 2. Select wire feed speed required on ‘wire speed’ knob 3. Set ARC force switch to middle position for medium weld inductance (know as choke on traditional welding power sources) Low setting = Soft ARC (less splatter & penetration) High setting = Strong ARC (more penetration) 4. Ensure you are wearing the correct safety clothes & equipment for welding (I.
Gasless wire = Negative torch – Positive earth Maintenance Routine and periodic maintenance WARNING! ELECTRIC SHOCK CAN KILL Turn the input power OFF at the mains switch & fuse box and remove mains plug from socket before working on this equipment. Have a qualified electrician install & service this equipment. Allow machine to sit for 5 minutes minimum after disconnection from mains power to allow the power capacitors to discharge before working inside this equipment.
