Arc Welder
The arc welder is an important machine in the game, it being needed for building key machines in the progression of the mod.
Crafting
It is made in the anvil with:
Usage and I/O
The arc welder has three item slots and one fluid slot. Some recipes take in a fluid, others don't and only have input items. Each recipe has a specific power consumption, measured in HE/t and amount of time required, measured in ticks.
For I/O, the arc welder is more special. Each of the three item slots are color-coded (red, yellow and green respectively), which correspond to those of the welder's ports(4 red, 4 green and 2 yellow). The fluid input can be done on any of the welder's ports.
Uses
One core feature of the arc welder is welded plates. They are made out of two cast plates which are three ingots each, thus 6 ingots for each welded plate. Welded plates are used in machines that are important to the progression of the mod, such as the oil refinery, the Watz Power Plant and the fusion reactor.
Besides its use for welded plates, it also has simplified recipes for frequently used components, such as circuits and motors.
It is also the main machine used in the assembly of generic missiles.
