1. Connection of Power Supply Cables
A primary power supply cable is fitted to this welding equipment. Connect
the power supply cable to the correct voltage, as stated on the rating plate
attached to the machine. The primary cable should be fitted with the correct
plug to avoid overheating.
2. Connection of Output Cables
Two twist lock sockets are situated on the front panel of this welding power
source. Insert the output cable plugs and twist to lock firmly. It is possible
to damage both the plug and socket, if the plug and the socket are
incorrectly or loosely connected.
For MMA welding the electrode holder cable should normally be connected
to the positive terminal, while the work piece should be connected to the
negative terminal. The two modes of connection of DC welding equipment
are as follows:
• Straight polarity: electrode holder to "-", work piece to "+";
• Reverse polarity: electrode holder to "+", work piece to "-"
• [for D.C. Tig welding the electrode should be negative (-ve)]
Connect according to the electrode manufacturer's recommendations,
(normally displayed on the packet), as incorrect connection may cause
unstable arc, spatter or freezing of rod to work piece etc. If the distance
between work piece and this power source is over 50 M, it may be
necessary to increase the diameter of cable in order to maintain voltage
output.
