Chicago electric 90 amp welder manual

So here are my thoughts: It is a good welder. Not a great welder, not a bad welder but a good welder. The ground clamp looks like the clamp on my battery charger. It works fine for everything less than the welder's max settings. When the welder is maxed out the ground clamp spot welds itself to whatever it's attached to. Everything gets hot including the ground lead 4awg , the torch lead it has a 10awg wire in it , the torch, and the welder.

It doesn't have a gas solenoid so the valve is in the torch making the trigger harder to push than other welders. The verdict: It is cheap and it welds. I've put a ton of hours on it so far and it hasn't burst into flames. I would buy it again if this one died. I plan on changing the ground clamp to a real ground clamp. As far as the capacitor mods, unless you are doing them for fun I don't think it is worth it.

It's arc is fine and this welder can barely hold it together at amps. Do not use the welder if the switch does not turn 4. Store idle welders out of the reach of children and it on and off. Any welder that cannot be controlled do not allow persons unfamiliar with the welder or with the switch is dangerous and must be repaired.

Have a plug installed by a certified electrician. Do not use the Welder if the power cord or plug is damaged. Turn the Welder to OFF and unplug it before proceeding. Page 9 6. Turn the Feed Tensioner counterclockwise loosen it enough to pull it up, releasing tension.

Swing the Feed Swing Arm out. Note: Do not loosen the Feed Tensioner too much, or it will come apart. Feed Swing Feed Tensioner 7. Loosen and remove the Feed Knob. Compare the wire diameter marked on the Wire Spool with the stamped number on the top of the Feed Roller. To prevent serious injury from fire or electric shock: 1. Do not touch anything, especially not the Ground Clamp, with the Gun or welding wire or an arc will be ignited. Page 11 If the wire stops instead of bending, turn the welder to OFF, unplug it, slightly tighten the Feed Tensioner clockwise , and try again.

Make practice welds on pieces of scrap the same thickness as your intended workpiece to practice technique before welding anything of value. Clean the weld surfaces thoroughly with a wire brush or angle grinder; there must clamps be no rust, paint, oil, or other materials on the weld surfaces, only bare metal. Press and hold Trigger and contact area to be welded with electrode wire to ignite arc. For a narrow weld, you can usually draw the wire in a steady straight line, this is called a stringer bead.

If this happens, rest the Gun on an electrically non-conductive, heat-resistant surface, such as a concrete slab, well clear of the ground clamp. Spatter that is grainy and large is a problem. Periodically remove the Right and Left side panels, and using compressed air, blow out all dust from the interior. Make sure that the entire Gun is completely cool and that the Power Cord is unplugged from the electrical outlet before proceeding.

Remove the Nozzle as explained in the previous subheading.
