GUN AND CABLE ASSEMBLIES
GENERAL
The
GUN CABLE CONNECTIONS
Lay the cable out straight. Insert the male end of the welding conductor cable into the brass block on the front of the
HANDLING PROCEDURES
1.Do not kink or pull the cable around sharp corners.
2.Keep the electrode cable as straight as practical when welding or starting the electrode through the cable.
3.Do not allow dolly wheels or trucks to run over the cables.
4.Keep the cable clean by following the maintenance instructions.
5.Use only clean,
6.Replace contact tip when the arc starts to become unstable or the contact tip end is fused or deformed.
LN-8S AND LN-8SE CONTINUOUS FLUX FEED (SUBMERGED ARC)
Connect the loose end of the hose to the tube at the back end of the welding gun. Tighten the hose clamp. If the hose is taped to the gun cable, be sure it is not collapsed or deformed as this could cause flux feed- ing problems.
The air for the automatic flux feeding system is obtained from the regular plant compressed air sys- tem, providing the plant system pressure is between 60 and 120 psi (414 and 827 kPa). The tank is equipped with a pressure regulator to reduce the input pressure to the 30 psi (207 kPa) required for the flux feeding system. This pressure is set at the factory before the machine is shipped. When the
Connect the input air hose to the street elbow located at the right side of the flux tank. A quick disconnect should be installed between the elbow and the input hose.
The air tank is equipped with a water and dirt separa- tor. Water separated from the input air feeds down through the long flux filled tube located at the input connection. It is exhausted from the system through the coiled tube below the flux tank. There is always a small amount of air and possibly water coming out of the end of this tube.
