Variable Frequency Weld Controls
12.10 Weld controls and timers (114 KB)
Variable Frequency gives the same improved welding results using transformers which do not require expensive diodes for rectification of the secondary circuit. The diodes often represent a large capital and operational cost, so there are considerable cost reduction when compared to MF systems, both on purchase and operationally.
Compared to an AC welding control, the variable frequency welding control has higher heating efficiency and lower peak currents. This relates to shorter weld times with lower mains power requirements.
Main Features:-
- Welding frequency is programmable between 25Hz and 400Hz.
- Transformers can be wound to suit required frequency or control programmed to match existing transformer.
- 64 weld programmes
- Three pulses in each weld
- Heat stepping
- Programmable weld force within sequence
- Programmable outputs for (e.g.) robot interface
- Weld count function
- Spot and seam modes
- Full monitoring of each weld pulse
- Automatic re-weld facility (selectable)
- Simple hand held pendant
- Fully networkable
