The wire feed rate is easily adjusted without going back to the welder, since we put the wire feed adjustment right in the bottom of the handle. We use a special notched tip for welding aluminum - the tip transfers the welding current to the wire better since there is a slight bend in the notch, forcing the wire to contact the tip.The notch also makes it much easier to remove a burnback if the wire burns back to the tip. 1 Plug the 110 v plug supplied with your RGS-500C into a 110V outlet on the front of your Bobcat Welder. 2 Connect the gas hose to your regulator. 3 Set the machine to the CV setting. 4 Connect the power cable to correct lug on your Bobcat Welder.
