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.

Results Better control of heat input in the weld, resulting in:

• Reduced warping and burnthrough on thin materials.

• Smaller heat-affected zone – good for thin material.

• Smaller bead profile without compromising proper penetration.

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 “Set It/See It” Operation:

• Flashing indicator light lets you see the pulse rate before you strike an arc.

Micro-Start™ II Technology controlled ramp down helps precisely fill the weld crater for quality results.

Micro-Start™ II Technology minimizes high frequency and ‘hot starts’ to deliver soft arc starts without arc wandering for AC and DC welding.

A CLOSER LOOK

AC Auto Balance® Controls — Automatically sets the optimal cleaning vs. penetration level for aluminum welding!

What Is It?

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 Balance® 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.

Easy Operation:

• Set it and forget it or override when you choose to customize the settings.

• Fan-As-Needed (F.A.N.)™ minimizes repeated heating and cooling of internal components, keeps dust and dirt build-up to a minimum and saves on electricity costs.

• Engineered cooling air routing brings clean air in from the top and exhausts at the bottom to draw and collect less dirt in the machine.

• Compare these reliability enhancing design features:

— Crimped and soldered power connections.

— Wound and varnished electrical coils do not require coil spacers used on competitive models.

— Locking tabs on PC board connectors eliminates loose connections.

• Tough testing cycles ensure long service — dropping, jerking, rolling, shipping, vibration, resistance to real world extreme conditions, and extended in-service life testing.

• CSA C/US certified.

• Lincoln three-year warranty on parts and labor.
