To address low open-circuit voltage on your Miller Welding System, verify the position of the Process/Contactor switch.
What to do if there is no remote amperage or voltage control on a Miller Big Blue Air Pak 600?
To restore remote fine amperage or voltage control on your Miller Welding System, check and secure the connections to the Remote 14 receptacle.
What to do if there is no weld output on my Miller Welding System but the generator power is okay?
If your Miller Welding System isn't providing any weld output but the generator power is fine at the AC receptacles, there are several things to check. First, make sure the Process/Contactor switch is in an Electrode Hot position, or in a Remote On/Off Required position and the remote contactor is connected to the Remote 14 receptacle. Next, try resetting supplementary protectors CB3 and CB9. Also, check the connections to the Remote 14 receptacle to ensure they are secure. If the VRD switch S5 is On, inspect the voltage feedback wires at the output terminals. Finally, inspect fuse F2, and replace it if it's open.
Why is the weld output erratic on my Miller Welding System?
If you're experiencing erratic weld output with your Miller Welding System, start by checking and tightening all connections, both inside and outside the unit. Ensure that your connection to the workpiece is clean and tight. Use dry, properly stored electrodes. Remove any excessive coils from your weld cables.
What to do if my Miller Welding System has no weld or generator output?
If your Miller Welding System has no weld output or generator power output at the AC receptacles, try these steps. First, disconnect the equipment from the generator power receptacles during start-up. Then, reset supplementary protector CB4. Check fuses F1 and F2, and replace them if they are open.
How to decrease high weld output on a Miller Big Blue Air Pak 600?
If your Miller Welding System is producing high weld output, first check the position of the Voltage/Amperage Adjust control.
Why is the weld output low on my Miller Big Blue Air Pak 600 Welding System?
If your Miller Welding System has low weld output, start by checking the position of the Voltage/Amperage Adjust control. Also, check fuses F1 and F2, and replace them if open. Try placing the VRD switch S5 in the Off position and attempt to weld.
