The penetration depth can differ according to welding
technique and torch position
H1, H2 – penetration depth
10. Welding using MMA process
The welding device can also be used for a stick electrode welding. To use that process turn the
MIG/TIG/MMA switch to MMA position. Connect the electrode holder plug into the positive socket
( + ) and the ground cable plug into the negative socket ( - ) leaving the polarization selector
unconnected. Using the welding current regulation knob (A) set the desirable welding current.
Please note that different electrode manufacturers may advise other polarization connections. In
such case please refer to electrode manufacturers information.
