DIGIPULS II is the very latest innovative MIG/MAG advanced welding machines offering the welding market superior quality welding. DIGIPULS II has been designed in a modular form for easy workshop mobility to suit all welding applications (manual or automatic). These machines offer easy to understand process options and parameter selection via the machine control panel or the wire feed unit.
Superior quality welding
Advanced processes and features
• Fully digitally controlled inverter: for process
repeatability and consequently higher welding
quality and simpler regulation
• In Synergic mode, more than 100 synergies
are available
• Soft switching inverter (increased efficiency
of the power source)
• Full range of processes
- Standard MIG/MAG
- Pulsed MIG/MAG
- Speed Short Arc™ (for high quality
thin sheet welding & root pass)
- Spray Modal™ (special for high
quality welding of aluminium)
- Cold Double Pulse (producing very
high quality welds on thin material)
- MIG brazing
- MMA coated electrodes
- Gouging (up to 6.3 mm diameter electrode)
• Powerful installation up to 420 A at 60%
• Full A1 automatic interface.
This level of synchronization does
not require an additional card,
for simpler automatisation
• Storage of 100 welding programs
(with expert wire feeder DVU P500
or advanced remote control RC JOB)
• Parameter locking with a digit code (with expert
wire feeder DVU P500 or advanced remote control
RC JOB). When this function is activated, the welder
can still fine-tune the parameters in a +/- 20% range
A user designed interface
for a really easy to use front panel
• Power source and wire feeder
A modular concept to fit
with all users’ requirements
Specify and build your own installation:
• Power source
• Wire feeders
• Cooling unit
• Harnesses (up to 50 m for shipbuilding
applications)
• Trolleys for the installation
and the wire-feeder
• Remote control
• Torches (standard, with potentiometer,
push-pull, automatic...)
More benefits for the user
• Small machine for easier access
• Light installation (37 kg for the power source)
• Compatible with motor generator
• A powerful 4-wheel feeder unit
Speed Short Arc TM (SSA TM )
SSA™ advantages • Large increase in travel speed |
Speed Short Arc TM provides a transfer mode using short circuits in a wire speed domain usually governed by globular conditions. The current values used in this mode are very different from those used in conventional “short arc” operation. Faster wire speeds require a medium current together with a large peak current in order to form and detach the droplet more quickly. MIG Brazing This is done by programming a digitally-regulated inverter where the current is controlled and where, for wire speeds governed by globular conditions, a specific current profile is required (particularly the rise and fall gradients of the current as well as the maximum peak current). This means the appearance of short-circuits is “forced” in a mode where, under natural conditions, they appear only erratically.
MIG brazing
MIG Brazing advantages • Effective on thin coated sheets |
MIG brazing appeared in the late 1990’ s as a better replacement for flame brazing. Since this time, it has gone from strength to strength and has become an essential process in automobile construction. The use of digita technology further increases the performance of this process both from the point of view of the quality of the joint produced, the productivity obtained and also the preservation of coatings applied to steel sheets for corrosion protection.
Cold Double Pulse
Cold Double Pulse |
Cold Double Pulse produces very high quality welds on thin material while avoiding distortion. The operating technique is made easier due to good control of the weld pool even on badly-prepared sheets. This sequencer mode automatically chains hot arc and cold arc regimes together.
Spray-Modal TM
Spray-Modal™ advantages • Large reduction in porosity |
This is a special transfer mode which uses a modulated current at frequencies of 30 to 50 Hz that produce vibrations in the liquid weld pool that have the effect of removing most of the hydrogen bubbles before the metal solidifies. These modulations strengthen the rigidity of the welding arc making it possible to use this process in all positions. The use of low frequency modulation also gives a TIG-like appearance to the weld bead. This process is particularly suitable for aluminium applications using sheet thicknesses of > 2 mm.
