*Regularly remove the spatter from the inside of the nozzle to prevent a short circuit. Use nozzle gel to minimize spatter buildup in the nozzle.
*Use appropriate wire listed on the parameter chart. Do not use rusty or dirty wire.
*Clean the dust and metal filings from the liner with compressed air. The dust is accumulated by friction between wire and liner, drive rolls and magnetic attraction of the wire to metal debris. If wire feeding is uneven this may be the problem.
*Do not over tighten the drive roll idler are, it will increase resistance, friction and possible deform the wire.
