Using this Miller AccuLock S MDX Conversion Kit for your M-25 MIG gun is easy. First, make sure your M-25 MIG gun is turned off and cooled down. Then, use the conversion diffuser to upgrade your legacy M-Series MIG gun to the AccuLock consumable line. When replacing the contact tip, the coarse thread will help you do it quickly. Remember, the shielding gas cools the contact tip tail inside the diffuser, so keep the gas flowing properly. For maintenance, clean the threaded nozzle regularly. The steel training ring on the diffuser helps the nozzle stay tight during use and cleaning. Store the kit in a dry place when not in use to prevent damage.
