The gas setup
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.
The welding machine
The welding machine has a setting for the welding current , as well as a setting for the wire feed rate. It uses wire of 0.6mm or 0.8mm 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 gound it using the grounding clamp. Read the welding introduction on what else precautions you might need to take.
The welding gun has a trigger. If it is pulled, gas is released from it, then wire is fed at a constant rate. The gas prevents the hot metal from exidizing. As soon as the wire gets close to the grounded workng peace 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.
Donation
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.
Suggested reading
Know the difference between the different welding methods
TODO: update the welding area and metal workshop pages for the new welding machine.
