[2] | Precision TIG® 225 ACLOSERLOOKACLOSERLOOK “Set It/See It” Pulse Control — Make attractive and consistent welds! What Is It? Pulse welding systems vary weld current between peak (high heat) and background current (low heat) levels. Adjusting the pulse frequency controls the level of heat input applied to the weld relative to the weld travel speed. For the Precision TIG® 225, pulse frequency can be varied Results Better control of heat input in the weld, resulting in: • Reduced warping and burnthrough on thin materials. • Smaller heat-affected zone. • Smaller bead profile without compromising proper penetration. from 0.1 to 20 pulses per second. puL E FrEquEncy# number of pulses per econd PeaBacgdHghHea(Pea) LHea(Bacgd) ime Weldingcurrent SmallerHeatAffectedZoneSmallerHeatAffectedZoneSmallerBeadProfileSmallerBeadProfile Sa dadTIGW d 4 dTIGW d (a 60a ) (a 60a ) Great For • Thin materials – Faster pulse settings help to narrow the bead profile and minimize the heat-affected zone and resulting warping or burnthrough. • Consistent appearance – Slower pulse settings aid in timing the application of filler metal to produce the consistent stacked bead appearance associated with high quality TIG welding. • Maintaining a steady welding rhythm. Easy Operation: • Flashing indicator light lets you see the pulse rate before you strike an arc. AC Auto BalanceO Controls — Automatically sets the optimal cleaning vs. penetration Easy Operation: level for aluminum welding! • Set it and forget it or override when you choose to customize What Is It? the settings. When aluminum welding, the positive (+) portion of the AC welding amperage cleans the oxides from the aluminum surface. The negative (-) portion delivers more heat input, increasing penetration level. Patented AC Auto BalanceO automatically sets the ratio of cleaning action (+) versus penetration (-) based on amperage. Manual balance control provides the flexibility to customize the arc to your preference.
