5.Hand solder wire at fitting lip until the solder begins to flow freely (Figure 6). When this occurs, squeeze handles and remove solder gun.

WARNING Do not overheat fitting.

WARNING Solder gun stainless steel sleeves and carbon tips remain hot. Do not touch. Do not lay on sur- faces that may be damaged until sleeves and tips have cooled.

6.If the joint to be soldered is in a difficult to reach location, it is not necessary to clamp the carbon tips around the tube. The carbon tips only have to be in contact with the fitting (Figure 7).

WARNING Do not clamp or touch stainless steel sleeves, threaded studs or lock nuts against the tube or fittings. If this happens, electrical arcing or excessive cur- rent draw may occur, kicking out the circuit breaker.

7. Switch the unit OFF when not in use.

WARNING Do not store the handle in the case until it has cooled. They can damage the power cord or sol- der gun cables if they are too hot.
