Better control for starting, arc stability and crater fill.

IN NOW CLUDES for AC WALUMINUM ELDING

Great Starting

Micro-Start II™ Technology minimizes high

frequency and ‘hot starts’ to deliver soft arc starts without arc wandering for AC and DC welding.

Stable, Focused Arc

Micro-Start II™ Technology aids arc stability

THROUGHOUT THE WELD CYCLE –

even at the lowest amperage!

Precise Crater Fill

Micro-Start II™ Technology

controlled ramp down helps precisely fill

the weld crater for quality results.

What Is It?

Pulse welding systems vary weld current between peak (high heat) and background current (low heat) levels. Adjusting the pulse fre- quency 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.
