PMC Pulse Multi Control

THE OPTIMIZED PULSED ARC

PMC and its optimized pulse characteristics equal high-quality welds at high speeds.
Thanks to the penetration and arc length stabilizer, controlling the arc has never been so easy.

QUESTIONS ABOUT PMC?

PMC takes the pulsed arc and its stabilizers to a whole new level. The modified process is characterized by PRECISELY REGULATED, LOW-SPATTER DROPLET DETACHMENT. At the same time, PMC generates a powerful and stable arc which RESULTS IN PERFECT CONTROL OF THE WELD POOL. This enables our users to AVOID IMPERFECTIONS. The welding results are always reproducible and stable.

MANUAL WELDING WITH PMC

WELD VERTICAL-UP SEAMS AT TOP SPEED WITHOUT OSCILLATING MOTION

The PMC Welding Package contains several characteristics which offer welders numerous advantages. This provides optimum support for every application so welders can achieve a perfect seam. For example, PMC Mix is ideal for vertical-up seams, enabling up to 40% higher speeds – and no oscillating motion.

 

Package contains:

  • Universal
  • Arc blow
  • Dynamic
  • Galvanized
  • Galvannealed
  • Gap bridging
  • Mix
  • Multi arc
  • PCS

PMC MIX

THE POWERFUL ARC WITH GOOD GAPBRIDGING ABILITY.

This characteristic enables high welding speeds compared to a conventional dip transfer arc. This is achieved by combining a pulsed and LSC dip transfer arc.

PCS – PULSE CONTROLLED SPRAY ARC

PCS COMBINES THE ADVANTAGES OF PULSED AND SPRAY ARCS IN ONE CHARACTERISTIC AND AVOIDS INTERMEDIATE ARCS.

The result is a smooth transition from a pulsed to a spray arc, which reduces welding spatter. The PCS characteristic improves results, particularly for small gaps, fillet welds, and root passes.

UNIVERSAL

ALL-AROUND BETTER WELDS.

This characteristic can be used for the majority of welds, regardless of seam profile or position.

PMC ARC BLOW

STABLE ARC WHEN EXPOSED TO EXTERNAL MAGNETIC FIELDS.

Improved properties against arc break – due to arc blow caused by external magnetic fields.

PMC DYNAMIC

AGGRESSIVE ARC WITH HIGH ARC PRESSURE – AND SMALL ARC FOCUS.

These properties result from a combination of high current and low voltage. This makes the characteristic ideal for narrow welds with a small opening angle. They are also ideal for applications which require high speeds and high penetration.

ROBOTIC WELDING WITH PMC

Robotic welding has a wide range of requirements. Whether it is higher welding speeds, perfect seam appearance, or reproducible quality, Pulse Multi Control meets all these requirements in full. The result is a package of different characteristics that is perfectly tailored to the customer’s requirements.

PMC MIX DRIVE

GOOD GAPBRIDGING ABILITY.

Here we are using a push-pull welding torch. The combination of reversing wire movement and cyclical process switch enables us to accelerate the welding of vertical-up seams. The bonus is a TIG seam appearance at high speed – with ultra-light sheet gauge applications up to 3mm.

PMC MIX RIPPLE DRIVE

TIG-LEVEL SEAM APPEARANCE.

The PMC characteristic for visually impressive seams. The result is elegant seam rippling with a TIG appearance. However, thanks to the combination of a coordinated pulse process and defined pause times, the speed is considerably higher than with TIG.

PMC BRAZE

CHARACTERISTIC FOR MIG/MAG BRAZING.

High brazing speed, reliable wetting, and good flow of braze material.

PMC MULTI ARC

INFLUENCE OF SEVERAL ARCS.

Improved properties when a part is being welded by several arcs that influence one another.

PMC CLADDING

CHARACTERISTIC FOR OVERLAY WELDING.

Low penetration, low dilution, and wide seam flow for better wetting.

PMC GALVANIZED

FAST WELDING OF GALVANIZED SHEET METAL.

Thanks to the penetration and arc length stabilizers, this characteristic enables galvanized sheet metal to be welded at top speed. It also reduces the risk of zinc pores and zinc burn-off.

PAVING THE WAY TO THE PERFECT WELD – INTEGRATED

ASSISTANCE SYSTEMS

Our penetration and arc length stabilizers provide perfect support for welders. Both stabilizers in the PMC Welding Package enable consistently high welding quality at high welding speeds.

WELDING WITH PMC IN SPRAY ARC

CONSTANT PENETRATION WITH STABILIZER

With an activated penetration stabilizer, the TPS/i readjusts the wire speed instead of the welding current, thereby ensuring constant penetration.

An additional wire control keeps the current and penetration constant if the distance between the welding torch and the component changes. The arc becomes significantly more stable and the penetration is always constant.

ADVANTAGES OF THE PENETRATION STABILIZER:

/ Improved welding quality

/ Save on rework and costs

Ideal support for insufficient view or accessibility = stick out fluctuations are compensated for

Ideal for position welding

Narrower opening angles can be used – saving on filler material

ARC LENGTH STABILIZER

CONSISTENT ARC LENGTH

The arc length stabilizer automatically compensates for imperfections. The arc length is kept constant regardless of the welding voltage. As a result, the seam quality and appearance remain unchanged even if the torch position changes or component tolerances vary.

 

OPTIMUM SUPPORT FOR THE FOLLOWING CIRCUMSTANCES:

/ Dynamic, changing position of the torch

/ Component tolerances: changing sheet thicknesses or gaps

/ Uneven heat dissipation

 

THE BENEFITS

/ No need for the welding operation to be interrupted or for manual readjustment of the arc length when the torch position changes

/ Quick determination of parameters

/ Focused arc

/ Faster welding speeds can be achieved
