AVOIDING WIRE FEEDING

PROBLEMS

Wire feeding problems can be avoided by observing the following gun handling procedures:

1.Do not kink or pull cable around sharp corners.

2.Keep the gun cable as straight as possible when welding or loading electrode through cable.

3.Do not allow dolly wheels or trucks to run over cables.

4.Keep cable clean by following maintenance instructions.

5.Use only clean, rust-free electrode. The Lincoln electrodes have proper surface lubrication.

6.Replace contact tip when the arc starts to become unstable or the contact tip end is fused or deformed.

7.Keep wire reel spindle brake tension to minimum required to prevent excess reel over-travel which may cause wire “loop-offs” from coil.

8.Use proper drive rolls and wire drive idle roll pres- sure for wire size and type being used.

FAN CONTROL

The fan is designed to come on when input power is applied to the POWER MIG 200 and go off when power is removed.

INPUT LINE VOLTAGE VARIATIONS

High Line Voltage — Higher than rated input voltage will result in output voltages higher than normal for a given tap setting. If your input line is high, you may want to select a lower voltage tap than given on the recommended procedure chart.

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 normal for a given tap setting. If your input line is low, you may want to select a higher voltage tap than given on the recom- mended procedure chart.

WIRE FEED OVERLOAD

PROTECTION

The POWER MIG has solid state overload protection of the wire drive motor. If the motor becomes over- loaded, the protection circuitry turns off the wire feed speed 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 elec- tronics.

WELDING THERMAL OVERLOAD PROTECTION

The POWER MIG 200 has built-in protective ther- mostats that respond to excessive temperature. They open the wire feed and welder output circuits if the machine exceeds the maximum safe operating tem- perature 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.
