4-2 Selection of welding cable
The longer the welding cable and the larger the current, a welding cable of larger size is required.
Prepare a cable of appropriate size as selected out of the following table depending on the required
welding current and cable length.
Relation between cable length and size (sectional area) for reducing cable's voltage drop to 4V or less

4-3 Welding Cable and Polarities
(a) Firmly connect the welding cable to output terminals located in the lower part of the control
panel.
Make sure to mount a terminal to the tip (connection).
[Caution] (1) The welder will be damaged, if the cable is damaged or if tightness of connecting screws
is insufficient.
Repair damage to the cable, and be sure to tighten connect screws.
(2) If any cable end lead is connected to a terminal in a circular form after stripping, heat
generation may arise due to faulty contact. Also burn to the insulator and short-circuit
caused by contact of the lead with the welder body may result.
(b) (+) and (-) are marked on output terminals. Select the polarity depending on the contents of
the work. Typical use of polarity is shown below.
