Vertical stroke spot and projection welders
PPS range suitable for spotwelding only, whilst PPN machines are more versatile.
A large variety of MF series, i.e. Medium Frequency versions in DC plus PPN3FCC, DC conventional.
BSW bench welders complete this family.
VERTICAL STROKE PROJECTION WELDERS MF
TECHNICAL ADVANTAGES
DIRECT CURRENT
- High quality joints
- Large power for projection welding
- Large power for welding with increased arm lengths
- The presence of magnetic materials between the arms does not affect the welding
- Long electrode life
- Highest efficiency
- Reduced welding time
THREE PHASE MAINS SUPPLY
- Balanced power absorption on the three mains phases
- Low primary consumption
- Lower cost for electric power
- High power factor and output
MIF
- Monitoring of the welding process every 1 millisecond (1000 Hz) versus traditional 20 millisecond (50 Hz).
- Shorter welding times and lower welding current, by saving approx 30% mains consumption
- Welding tasks previously solved by capacity discharge welding (C) are now possible by MF range in a more economic way
- Quick upsloping to the preset welding current
- Less thermal loss through the workpiece and electrodes
