WELDING LEADS

A selection of MMA welding lead sets and earth return leads.  Welding leads are an essential part of the welding circuit.  A poor earth connection can cause issues in the welding process, leading to weld defects or poor arc characteristics.

When selecting welding leads, the cable size and the attachments (such as earth clamp and electrode holder) should be sufficient to allow the welding current being used.  Over current through under rated components or cables can cause overheating and can be potentially dangerous.  An oversized cable is more expensive and is heavier to transport and handle.

The industry standard for welding machine connections is a keyway brass plug which secures by twisting.  These connections are often called dinse connections.  Depending on the size of the machine, these sockets can be different sizes.  The size of the plug also denotes the size of the welding cable it can be connected to, for example – a 3550 dinse plug can accept 35mm or 50mm welding cable.

In some stick welding applications, the user may prefer to use a lighter weight set of cables nearest the job and heavier weight welding cable extension leads to cover a longer distance.  Sometimes referred to as “whip ends” the lighter weight leads are easier to work with and offers better dexterity.

In MMA welding, there are a number of options of electrode holder, depending on the welders preference.  A crocodile type earth clamp (sometimes called welding tongs) allow quick swap over of electrodes.  The jaws usually have cut outs to allow fitment of welding electrodes at 2 or 3 different angles.  Many prefer a twist type holder where the welder twists the handle to open and shut the electrode gripping jaws.
