Setting The Wire Feed Pressure - ESAB MEK 4 Service Manual

SETTING THE WIRE FEED PRESSURE

Start by checking that the wire can run freely through the wire liner, and then adjust the
pressure of the wire feed rollers. It is important that the pressure is not too high.
Figure 1 Figure 2
To check for correct feed pressure, feed the wire out against a piece of insulating material,
such as a piece of wood.
With the pistol held about 5 mm from the wood (Figure 1), the drive rollers should slip.
With the pistol held further away from the wood (about 50 mm, as shown in Figure 2), the
wire should continue to feed out, bending as it does so.
