Thank you for selecting the R-Tech I-MIG160 Portable Inverter MIG/MMA Welder. The I-MIG160 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 I-MIG160 as much pride as we have taken in making this product for you.
Introduction The R-Tech I-MIG160 is a member of our highly 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.
Rated Output Current Generator required KVA Duty Cycle @ 130 AMPS 130Amps Max 4.8KVA Duty Cycle @ 100 AMPS 60% @ 40ºC Duty Cycle @ 75 AMPS 100% @ 40ºC 30-130 AMPS 55-75V 18 KG Class F Output current Range No Load Voltage Gross Weight Insulation 35% @ 40ºC 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.
WARNING! Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above personnel. Tilting Machine must be placed on a secure level surface or on a recommended undercarriage/trolley. This machine may topple over if this procedure is not followed. Environmental Rating The welding power source carries the IP21S rating. It may be used in normal industrial and commercial environments. Avoid using in areas where water / rain is around.
1. Keep the welder input power lines as short as possible and enclose as much of them as possible in metal conduit or equivalent shielding. There should be a good electrical contact between this conduit and ground (Earth). 2. Keep the work and electrode leads as short as possible. Tape the leads together where practical. 3. Be sure the torch and earth leads rubber coverings are free from cuts and cracks that allow welding power leakage 4.
Connections for IMIG 160 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.
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 the 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 the Machine in MIG mode 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.
Operating the Machine in MMA mode Connect the following: 1. Negative welding power connector Connect the earth cable dinse plug into here and twist to secure 2. Positive welding power connector Connect the electrode holder cable dinse plug into here and twist to secure Most popular rods have a positive welding electrode and negative earth. If you are using special electrodes check the manufacturer’s recommendation for correct polarity of welding electrodes and connect as required. 1. 2. 3. 4. 5.
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. Do not touch electrically live parts 1.
Troubleshooting Service & repair should only be performed by R-Tech welding trained personnel. Unauthorized repairs performed on this equipment may result in danger or injury to the technician and machine operator and will invalidate your warranty.
