3.3 SEQUENCE OF OPERATIONS FOR EQUIPMENT START-UP
1. Connect the power plug to the mains power supply.
2º. Turn on the main power switch.
3º. Set up the equipment according to the desired welding process. From section 3.4 of this manual you will
find the instructions for the equipment installation and adjustment according to the work to be carried out.
4º. The welding operation can begin.
3.4 STICK WELDING (MMA).
3.4.1 STICK WELDING (MMA) INSTALLATION.
When welding with coated electrodes, we must connect the welding clamp (F) and the welding ground (G)
according to the polarity recommended by the electrode manufacturer of the electrodes.
Normally, most electrodes should be positioned with direct polarity, i.e. the welding clamp placed on the
negative pole and the ground placed on the positive pole. However, welding with basic or special electrodes is
usually carried out with reverse polarity, i.e. the electrode clamp is placed on the positive pole and the earth on
the negative pole. In each case, the instructions provided by the electrode manufacturer must be observed. The
figure shows the preparation of the equipment for this mode of work, in this case observe that the polarity of
use is reversed, that is to say, the welding clamp is placed on the positive pole.
