1. When proper rod is used:
• The bead will lay smoothly over the work without ragged edges
• The base metal puddle will be as deep as the bead that rises above it
• The welding operaon will make a crackling sound similar to the sound of eggs frying
2. When a rod too small is used
• The bead will be high and irregular
• The arc will be dicult to maintain
3. When the rod is too large
• The arc will burn through light metals
• The bead will undercut the work
• The bead will be at and porous
• Rod may freeze or sck to work piece
Note: Rate of travel over the work also aects the weld. To ensure proper penetraon and
enough deposit of rod, the arc must be moved slowly and evenly along the weld seam.

1. Seng the Amperage Control
The welder has an innite output current control. It is capable of welding with 2.0mm and
2.6mm and 3.2mm electrodes.
There is no golden rule that determines the exact amperage required for every situaon.
It is best to pracce your welds on scrap metal which matches the metals you intend to
work with to determine correct seng for your job. The electrode type and the thickness
of the work piece metal determine the amount of heat needed in the welding process.
Heavier and thicker metals require more voltage (amperage), whereas lighter and thinner
metals require less voltage (amperage).
