AVOIDING WIRE FEEDING PROBLEMS
Wire feeding problems can be avoided by observing the following
gun handling procedures:
• Do not kink or pull cable around sharp corners.
• Keep the gun cable as straight as possible when welding or
loading electrode through cable.
• Do not allow dolly wheels or trucks to run over cables.
• Keep cable clean by following maintenance instructions.
• Use only clean, rust-free electrode. The Lincoln electrodes
have proper surface lubrication.
• Replace contact tip when the arc starts to become unstable or
the contact tip end is fused or deformed.
• Keep wire reel spindle brake tension to minimum required to
prevent excess reel over-travel which may cause wire "loop-
offs" from coil.
• Use proper drive rolls and wire drive idle roll pressure for wire
size and type being used.
FAN CONTROL
The fan is designed to come on automatically when a weld arc is
established. The fan will also stay on when the machine's welding
and feeding are disabled during thermostatic over temperature
protection. (See Welding Thermal Overload Protection)
INPUT LINE VOLTAGE PROTECTION
High Line Voltage — If the line voltage exceeds 110% of rated
input voltage, the output will be reduced to the lower level to
protect voltage rating of the capacitor bank.
Low Line Voltage — You may not be able to get maximum output
from the machine if the line voltage is less than rated input. The
unit will continue to weld, but the output may be less than what is
set.
WIRE FEED OVERLOAD PROTECTION
®
The POWER MIG
360MP has solid state overload protection of
the wire drive motor. If the motor becomes overloaded, the
protection circuitry turns off the wire feed speed weld output and
gas solenoid. Check for proper size tip, liner, and drive rolls, for
any obstructions or bends in the gun cable, and any other factors
that would impede the wire feeding.
To resume welding, simply pull the trigger. There is no circuit
breaker to reset, as the protection is done with reliable solid state
electronics.
WELDING THERMAL OVERLOAD PROTECTION
®
The POWER MIG
360MP has built-in protective thermostats that
respond to excessive temperature. They open the wire feed and
welder output circuits if the machine exceeds the maximum safe
operating temperature because of a frequent overload, or high
ambient temperature plus overload. The thermostats automatically
reset when the temperature reaches a safe operating level and
welding and feeding are allowed again, when gun is retriggered.
