for aluminium filler wires select the correct feed roll type from the chart supplied and adjust

for the minimum pressure necessary for reliable filler wire drive without deformation of the

wire itself.
for flux-cored filler wires select a knurled feed roll to achieve better wire grip.

NOTE!

Slight slippage is recommended in the case of aluminium filler wires. This ensures that the

soft wire is not deformed and flattened and that the feed rolls skid over the soft wire if it stops when

passing through the gun liner or contact tip.

for aluminium and stainless steel filler wires, always use Kemppi DL Chili gun liners.

These liners are especially developed by Kemppi and significantly reduce friction losses, so

improving welding performance and quality.
