A Welder is one of the tools you start with. Used to weld sheets onto frames, see Iron Frames for example.

When used, Welding Torches will generate toxic fumes, heat and a flame. Arc Welders generate heat but do not ignite flammable gases.

A gas powered Welding Torch has a Canister with a Fuel mixture of 66% H2 and 34% O2 and unlike other devices, has a minimum fuel operating temp. More testing required to find the exact temp. It may appear on but not weld if the fuel is too cold.

Arc Welder[edit]

The Arc Welder uses a battery instead of gas to operate making it easier to refill, and it welds things more quickly, but it drains its battery faster than the other tools, and its more expensive to make. Its MK II version is more resistant to hot environments, thus really only being useful in hot atmospheres such as Vulcan and Venus.
