How to fix a Miller DYNASTY 700 Welding System with no weld output and is completely inoperative?
If your Miller Welding System has no weld output and is completely inoperative: 1. Ensure the line disconnect switch is in the On position. 2. Check and replace the line fuses if necessary, or reset the circuit breaker. 3. Check for proper input power connections.
Why is the tungsten electrode oxidizing on my Miller Welding System?
If the tungsten electrode is oxidizing and not maintaining its brightness after welding with your Miller Welding System, consider these potential causes: * Shield the weld zone from drafts. * Increase the postflow time. * Check and tighten all gas fittings. * Water in torch. Refer to torch manual.
Why is the arc wandering on my Miller Welding System?
If you're experiencing a wandering arc with your Miller Welding System, try the following: * Use the proper size tungsten. * Use properly prepared tungsten. * Reduce the gas flow rate.
What to do if my Miller Welding System has no weld output but the meter display is on?
If the meter display is On but there's no weld output from your Miller Welding System, here's what you can do: * If you're using a remote control, ensure the correct process is enabled to provide output control at the Remote 14 receptacle. * Check, repair, or replace the remote control. * If the unit overheated and [Over][Temp] is displayed, allow the unit to cool with the fan On.
Why does my Miller DYNASTY 700 Welding System have erratic or improper weld output?
If your Miller Welding System is producing erratic or improper weld output, consider the following: * Ensure you are using the correct size and type of weld cable. * Clean and tighten all weld and gas connections.
What to do if there is no 115 volts ac output at the duplex receptacle on my Miller Welding System?
If there is no 115 volts AC output at the duplex receptacle on your Miller Welding System, reset circuit breaker CB1.
Why is the fan not operating on my Miller DYNASTY 700?
The fan on your Miller Welding System is designed to run only when cooling is necessary. However, if you suspect it's not working correctly: * Check for and remove anything blocking the fan movement. * Have a Factory Authorized Service Agent check the fan motor.
