A stick welder amperage chart lists recommended current settings for different electrode types and diameters. These charts help operators select the correct amperage to achieve proper weld penetration and electrode performance.
Amperage requirements increase with electrode diameter. For example, a 1/8 inch E6010 electrode typically runs between 75 and 120 amps.

Polarity settings also affect amperage selection. DCEN (direct current electrode negative) is common for cellulose electrodes like E6010.
Material thickness plays a role in amperage choice. Thinner metals require lower amperage to prevent burn-through.
Charts vary by manufacturer and electrode classification. Always refer to the specific chart provided with your welder or electrodes.
Ambient temperature and welding position can influence optimal amperage settings. Adjustments may be needed for overhead or vertical welds.
Digital welders often have built-in amperage guides. Manual models require the operator to set amps based on the chart.
Incorrect amperage leads to poor arc starts, excessive spatter, or weak welds. Following the chart improves consistency and quality.
Some charts include amperage ranges rather than fixed values. This allows flexibility based on technique and joint design.
Always verify settings before striking the arc. Testing on scrap material helps confirm the correct amperage for the job.
