section 4 operation 1. Pulse Mig Arc Stability Many variables can affect the arc stability of pulse MIG welding. Some examples are: • • • • • • • • • Differences in shielding gas compositions Differences in weld wire chemistry Water vs. air cooled guns Base metal surface condition Tip-to work distance Variations on wire feed speed Wire feedability Long welding cables High resistance cables and connections When adverse conditions are present, the pulse arc stability is sometimes less than desirable.
section 5 maintenance 5.0. Maintenance And Troubleshooting A. Cleaning Periodically, remove the cover from the power source and blow accumulated dust and dirt from the air passages and interior components by using clean low pressure air. The frequency of cleaning required depends upon the environment in which the power source is used. It is imperative that all air passages be kept as clean as possible in order to allow adequate air flow to provide proper cooling.
section 5 maintenance G. IGBT Handling and Replacement WARNING STATIC ELECTRICITY can damage circuit boards and electronic components. • • Observe precautions for handling electrostatic sensitive devices. Use proper static--proof bags and boxes. What is ESD? A sudden transfer or discharge of static electricity from one object to another. ESD stands for Electrostatic Discharge. How does ESD damage occur? ESD can cause damage to sensitive electrical components, but is not dangerous to people.
section 5 maintenance G. IGBT Handling and Replacement (continued) Since IGBT gates are insulated from any other conducting region, care should be taken to prevent static build up, which could possibly damage gate oxides. All IGBT modules are shipped from the factory with conductive foam contacting the gate and emmiter sense pins. When mounting IGBT modules on a heatsink, certain precautions should be taken to prevent any damage against a sudden torque.
section 5 maintenance G. IGBT Handling and Replacement (continued) Insulated Gate Bipolar Transistor (IGBT) C2 E1 E2 C1 G2 E2 Set the VOM to ohms then check for continuity between all the legs of the IGBT. No continuity should be measured. Place the red probe to the Collector (C1) and the black probe to the Emitter ( E1). The VOM should read very high resistance or an open circuit. No shorts (continuity) should be measured. Repeat the steps on the second IGBT pair (C2 E2).
section 5 maintenance G. IGBT Handling and Replacement (continued) C2 E1 G2 E2 C1 E2 NOTE The power source should be more the 6 volts and less than 20. A 9 volt battery is common and works quite well. Once the IGBT is turned on, remove the power source and the unit should stay on. G2 C2 E1 E2 C1 E2 Short the gate leads (you can use your finger) to turn the unit off. This demonstrates the correct functioning of the unit.
section 5 maintenance H. Procedure for Checking Diodes Inspect the diode to determine if it is of the “ straight polarity “ or “reverse polarity” type. Refer to the following figure for typical marking of diode polarity. It is essential that a replacement diode be of the same polarity as the one removed.
