* Trouble starting the weld at the correct distance - Trim the wire to around 1/4" so that the gun can be closer to the work piece.

* Wire feeding at an erratic rate - Readjust drive roll pressure; clean the gun liner and replace if necessary. See the user manual for details on doing this.

Welding environments are often dirty so the {{#show: {{PAGENAME}} |?Has model}} holds up well to to dust by design and it is not critical to have it squeaky clean as a result. However, it is still recommended to wipe down the machine on occasion to prevent an excess of dirt buildup. It is important to clean slag buildup from the nozzle of the gun to increase its longevity and to inspect/repair the weld cable. To clean the nozzle, twist it off and then scrape away any slag with a pair of pliers. At this point you can apply a light coat of nozzle gel to the end of the nozzle to help prevent slag from sticking (this is found on the table to the left of the welder). Another routine maintenance procedure is the lubrication of the drive motor so that the wire feed system will keep functioning properly. For details on doing this refer to the user manual.
