MIG/MAG welding machine by Einhell.

To be used with welding gas for MIG welding or MAG welding.

This tool is not ready for use yet since not all commissioning steps have been completed. The process is not yet tracked on GitHub. Feel free to contribute to making it usable, any help is very welcome!

Gas Setup

The welding gas is at ~200 bar if the gas cylinder is full. A pressure reducer reduces this pressure. It also limits the flow rate of the gas. Notice the flow rate has a scale for each type of gas.

10 L/min is a good starting value for the flow rate. Both the bottle valve and the second valve have to be open for gas to flow. Turn the regulation knob to adjust the flow rate. Always turn the gas off at the bottle valve after usage to reduce leakage losses while keeping the pressure setting of the reducer.

Settings & Usage

The welding machine has a setting for the welding current, as well as a setting for the wire feed rate. It uses welding wire of 0.6 mm or 0.8 mm diameter. The wire spools can have up to 5 kg. If you swap in a wire of a different diameter, you must also change the contacting pipe (Kontaktrohr, see manual).

Before welding the metal workpiece, you need to ground it using the grounding clamp. Read the welding introduction on further precautions you might need to take.

The welding gun has a trigger. It turns on gas flow, electricity and wire feeder simultaneously. The gas prevents the hot metal from exidizing. As soon as the wire gets close to the grounded workpiece, a light arc is formed which melts the wire and the workpiece.

Turning the welding current too high might trip the circuit breaker. Just turn the current down and reset the circuit breaker.

Wear Parts

The gas nozzle is subject to extreme conditions and might get covered in slag and weld droplets over time. Replacement parts, perhaps even from ceramics, will be necessary at some point - but please regularly to clean the nozzle to keep it alive for a long time!

The inner nozzle (Stromdüse) needs to be changed when it wears out or you want to put in a different wire diameter. We have some spares in the office.

+=== Settings & Usage ===
-The inert gas (Argon) or active gas (CO2) is at ~200 bar if the gas cylinder is full. A pressure reducer reduces this pressure. It also limits the flow rate of the gas. Notice the flow rate has a scale for each gas. 11l/min is a good starting value for the flow rate. Both the bottle valve and the second valve have to be open for gas to flow. Turn the regulation knob to adjust the flow rate. Always turn the CO2 off after usage to reduce leakage losses.

-== Donation ==
+The inner nozzle ''(Stromdüse)'' needs to be changed when it wears out or you want to put in a different wire diameter. We have some spares in the [[office]].
-The Argon gas costs 70 Euro per 20 l filling, which lasts about 350 minutes of welding (the cylinder holds ~ 4000 l of argon) this gives a cost of about 20 cents per minute of welding. The wire costs about 40 euro per kg, which leads to costs of another 20 cents per minute (at 5.4g/minute, assumed 3cm/s wire speed). Thus I would suggest a donation of 50 cents per minute of actual welding time.
