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. - Page 7 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.
- Page 8 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.

Page 9: Controls And Settings
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 (Fig3.5) This feature allows you to record this value along with the preset welding voltage for easy setup to specific job when several different... - Page 10 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.
