2. Installation
2-1. Connection of the power wires
1. Each machine is equipped with primary power wire, according to the input voltage,
please connect the primary wire to the suitable voltage class.
2. The primary wire should be connected to the corresponding socket to avoid oxidization.
3. Use multimeter to see whether the voltage value varies in the given range.
2-2. Connection of output wires
1. All machine has two air sockets, connect the plug to the socket on the panel board,
and tighten it and make sure that it’s well-connected, or it may cause the damage
of both the plug and socket.
2. The electrode holder wire is connected to the negative terminal, while the work
piece is connected to the positive terminal; connect one terminal of the earth clamp
to the red air plug, and tighten it with hexagon spanner to make the secondary wire
well connected to the air plug, or the air plug may get burned.
3. Pay attention to the electrode of the wire. Generally, there are two ways of the DC
welder connection: positive connection and negative connection. Positive: electrode
holder to ,while work piece to “ + ” ; Negative: work piece to, while electrode holder
to “+” ; Choose the way according to the practical requirements, and wrong choose
may cause unstable arc and big splash, etc. Under this circumstance, renew the air
plug rapidly in order to change the poles.
4. If the work piece is too far away from the machine (50-100m), and the secondary
wire is too long, the section of the cable should be bigger to reduce the lower of the
cable voltage.
5. You can find a MIG central connector to connect your MIG torch. Disconnect the
electrode holder when welding in MIG mode.
