SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK CAN KILL.
•Turn the input power OFF at the welding power source before installation or changing drive rolls and/or guides.
•Do not touch electrically live parts.
•When inching with the gun trigger, electrode and drive mechanism are "hot" to work and ground and could remain energized several seconds after the gun trigger is released.
•Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.
•Only qualified personnel should perform mainte- nance work.
WELD CABLE SIZE
Table A.1 located below are copper cable sizes rec- ommended for different currents and duty cycles. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of minimizing cable drop.
LOCATION
Firmly secure the AutoDrive™ 4R220 wire feeder to a robot arm or fixture.
See L15169 iB and L15169 - 1 iC Mechanical
