4.6 Setting the pressure of the feed rolls

To ensure the ller wire runs smoothly into the welding gun wire liner you should adjust the

pressure of the feed rolls of the wire drive mechanism.

Turn the orange coloured pressure adjustment knob(s) in a clockwise direction to increase the

pressure applied to the welding ller wire, and anticlockwise to decrease it.

NOTE! Periodically remove and clean the short wire spiral located at the back of the wire feed

mechanism. See item D.

There is a graduation scale marked on the pressure arm above or below the orange

adjustment knob, depending on the Kempact RA used. For models tted with the two roll

GT02 wire drive system, the more pressure applied, the greater the number of graduation

marks visible. For models tted with the four roll DuraTorque wire drive system, the more

pressure applied, the fewer number of graduation marks visible.

For hard steel and stainless steel ller wires make sure there is sucient pressure applied,

so avoiding ller wire slippage in the feed rolls.

NOTE! Too much wire feed roll pressure may atten the ller wire, damage its coating, increase

friction and result in the ller wire sticking in the welding gun liner or contact tip. Also excessive

pressure will result in increased wear to wire drive roll bearings, reducing their life.
