The Rehm Megapuls 450, marked RMP 450 in the documentation, is a hybrid MIG/MAG power source with liquid cooling. The maker gives 450 A at a 60% duty cycle and 370 A in continuous 100% work. The machine welds in four modes: double pulse, pulse, synergy and manual mode.
What this machine is for
A margin of 370 A at a 100% duty cycle means a power source for long welds on thicker elements. Pulse tears the drops off without a short circuit with the pool, so there is little spatter and less work is left for grinding. Double pulse adds to this a slower modulation, which lays a regular ripple and lowers the amount of heat put into the material, and that matters on aluminium and on acid resistant steel.
The synergic mode leads the settings for the operator, the manual mode leaves him the voltage and the feed. The machine has programs for different metals, and the panel shows the thickness of the welded material, so you relate the settings straight to the part.
Features and equipment
- Double pulse: the modulation lays an even ripple and limits the heat put into thin material.
- Pulse: the drops pass into the pool without a short circuit, so the weld comes out without spatter.
- Synergic mode: the machine picks the voltage and the feed for the material and the wire you point to.
- Manual mode: you set the voltage and the wire speed yourself, without curves.
- Programs for different metals: changing the station over comes down to the choice of a program.
- Reading of the thickness of the welded material on the panel: you tie the settings to the part, not to abstract values.
- Liquid cooling: the circuit takes the heat from the torch in long work at a high current.

What to watch out for
The supply is 400 V in three phases, so the machine needs a power connection. The cooling runs on liquid, so before the start check the fluid level, the flow and the tightness of the quick couplings of the torch. The description does not list a torch, an earth cable or a wire feeder, confirm this equipment before you buy.
