How to restore 115 volts AC at the duplex receptacle on Miller Axcess 450?
If there is no 115 volts AC at the duplex receptacle on your Miller Welding System, reset the supplementary protector CB1.
What to check if gas does not flow on Miller Axcess 450 Welding System?
If the gas in your Miller Welding System does not flow, or does not stop flowing while the wire feeds, check the gas valve and flow meter.
Why does wire feed as soon as power is supplied on Miller Welding System?
If the wire feeds as soon as power is supplied to your Miller Welding System, check the gun trigger, consulting the gun Owner’s Manual.
Why wire burns back to gun contact tip on Miller Axcess 450?
If the wire burns back to the gun contact tip when using an electrode negative process on your Miller Welding System, ensure that the volt sense lead is connected to the work.
How to fix Miller Axcess 450 Welding System with no weld output?
If your Miller Welding System is completely inoperative with no weld output, first ensure the line disconnect is in the On position. Then, check and replace the line fuses if necessary, or reset the circuit breaker. Finally, verify that the input power connections are properly connected.
Why does the wire feed erratically on my Miller Welding System?
If the wire feed on your Miller Welding System is erratic, try these steps: 1. Readjust the hub tension. 2. Readjust the drive roll pressure. 3. Clean or replace any dirty or worn drive rolls. 4. Remove any weld spatter around the nozzle opening. 5. Replace the contact tip or liner, consulting the gun Owner’s Manual. 6. Check the motor control cable connections.
What to do if Miller Welding System has erratic weld output?
If your Miller Welding System shows erratic or improper weld output without displaying any errors, ensure that you are using the correct size and type of weld cable. Also, clean and tighten all weld connections.
How to troubleshoot Miller Axcess 450 Welding System when wire does not feed?
If the wire isn't feeding in your Miller Welding System, check the supplementary protector CB2 and reset it if needed. Also, inspect the motor control cable connections.
Why Miller Axcess 450 Welding System has no weld output but meter display is on?
If your Miller Welding System's meter display is on but there's no weld output and no error is displayed, check if the contactor indicator light is lit when the contactor line is asserted on.
