    Help Identifying Component Q2 - Miller d302K 3+12 Diesel Engine Driven Welder

    Hello, I am trying to identify a damaged component on a Miller d302K 3+12 Diesel Engine Driven Welder Voltage Regulator board. The board itself is labeled Assembly # 214954. The board is modular but can't find an easy replacement.

    There is a component that is damaged that I cannot identify due to it being damaged. It is marked as Q2 on the board. I've included a link to the technical manual, but it doesn't give much detail, at least none that I can understand.

    Can anyone could help me identify this component? I've tried to get as good of a picture of it as I can.
    The only visible letters on it are what appears to be a Z on the first line and a 6 on the second. Of course that could be a 9 and a Z.

    Thank you for you time.

      Have you tried to remove the top of the ic chip so you can read more of the part number but use a pick type tool and very carefully remove what looks like some type of glue on the top of the ic chip

          I will take a guess at ZXMP6A17G You should be able to clean off that material, If that transistor was bad I would expect more damage like a large hole in it.

              You guys are awesome! I will remove the chip and check it out. I'm willing to bet though that ZXMP6A17G is the one.

                  Reverse engineering of DoCreate DHJ567 handheld spot welder
                  by spleenharvester
                  Hello everyone

                  I attach a schematic and teardown photos for the DoCreate DHJ567 handheld spot welder. I bought this welder for temporary use while my supercapacitor welder was waiting for replacement parts. It cost only £24, though there is a screenless version available for £17.

                  Performance: The absolute maximum it can handle appears to be 0.15mm of pure nickel. Reliability was not great - welds were very inconsistent, ranging from weak attachment to burning through the strip. However, I was able to build a 5S2P pack without losing any cells. It's a bit difficult getting...

                  Activation of Management Engine after exchange Z590 chipset - ASUS PRIME Z590M-PLUS
                  by DynaxSC
                  Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.

                  For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent...

                  Is there any high current pouch battery that are size 60mmX80mm maximum thickness 21mm for a battery operated tab welder
                  by sam_sam_sam
                  I have a battery operated tab welder and the battery does not have enough current for the battery tab welder because after about 30 welded it does not have the same current output it voltage has gone down by at least 0.500 volts or maybe a more than that

                  I can fit 21700 battery cells in the enclosure it is very tight fit for four of them that are 35 amp high current capacity 35X4=140 high current output this should work a lot better than what is installed right now

                  I tested the battery cells there are installed right now and they are testing good with no issues that I...

                  Lincoln Electric LE31MP welder not turning on
                  by tibimakai
                  This is my own welder, that blew up while welding. There is no warranty on it. Purchased it a year ago, sealed box from Craigslist.
                  It worked great until now, about a year.
                  What I have found is a blown trace next to the main capacitors, it seems like also got damaged the SMPS IC, output MOSFET and a 1 Ohm resistor to the ground from the MOSFET.
                  After replacing these components, the relay, fans turn on and it sounds like it's working, but there is no output voltage for the welder, LEDs do not turn on.
                  So there are more components that are damaged.
                  I'm having a hard...

                  New Super Capacitor 5v DC Battery Spot Welder with a 12 volt power supply
                  by sam_sam_sam
                  This is a new item at Battery Hookup that I bought I have always wanted to buy a good capacitor battery stud welder but they are to expensive for my budget that I want to spend on one this was surprisingly moderate price for what it can

                  It came by FedEx today so I decided to try it out on some tabbing that my battery stud welder has a little issue making constantly welded with out having to redo some because it would not get hot enough to do it properly

                  Well right out the box when the super capacitor charges up with the setting as follows does a very good job the first...
