  If you're experiencing difficulty establishing an arc with your Miller Electric Welding Accessories due to a lack of high frequency, make sure the High Frequency Selector Switch is in the correct position. Also, ensure the torch cable isn't near any grounded metal. Inspect cables and the torch for cracked insulation or loose connections, repairing or replacing parts as needed. You might also need to increase the High Frequency Intensity Control setting and select the proper size tungsten. Finally, check and adjust the spark gaps if necessary.
