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.
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.
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.
