What to do if Miller Welding System has low, high, or erratic wire speed?
If you experience low, high, or erratic wire speed with your Miller Welding System, try the following: * Readjust the front panel settings. * Change to the correct size drive roll. * Readjust the drive roll pressure. * Replace the inlet guide, contact tip, and/or liner if necessary.
Why is the weld output low on my Miller MILLERMATIC DVI?
If the weld output is low on your Miller Welding System, connect the unit to the proper input voltage or check for low line voltage.
What to do if my Miller MILLERMATIC DVI has no weld output and the wire doesn't feed?
If your Miller Welding System exhibits no weld output and the wire doesn't feed, consider the following: * Ensure the power cord is securely plugged into the receptacle. * Check the power switch/circuit breaker and reset if needed; if the circuit breaker isn't tripped, replace the power switch. * Check circuit breaker CB1 and reset if necessary. * Replace the building line fuse or reset the circuit breaker if it's open. * Secure the gun plug in the receptacle, repair leads, or replace the trigger switch. * If the thermostat TP1 or TP2 is open (due to overheating), allow the fan to run, which will close the thermostat once the unit cools down.
Why does the electrode wire feeding stop during welding with my Miller MILLERMATIC DVI Welding System?
If the electrode wire feed stops during welding with your Miller Welding System, consider the following: * Straighten the gun cable and/or replace any damaged parts. * Adjust the drive roll pressure. * Readjust the hub tension. * Replace the contact tip if it's blocked. * Clean or replace the wire inlet guide or liner if it's dirty or plugged. * Replace the drive roll if it's worn or slipping. * Secure the gun plug in the receptacle, repair the leads, or replace the trigger switch. * Check and clear any restrictions at the drive assembly and liner.
What to do if Miller MILLERMATIC DVI Welding System has no weld output but wire feeds?
If your Miller Welding System has no weld output, but the wire feeds, ensure the work clamp is connected to provide good metal-to-metal contact. Also, replace the contact tip.
