COATED-ELECTRODE WELDING (MMA-WELDING MODE)
CONNECTIONS AND ADVICE
• Connect the cables, electrode holder and earth clamp to their plug connections.
• Respect the welding polarities and currents indicated on the electrodes' packaging.
• Remove the electrode from the electrode holder when the welding machine is not in use.
CHOOSING COATED ELECTRODES
• Rutile electrodes: very easy to use in any position with a direct current.
• Basic electrodes: suitable for all welding positions with a direct current, ideal for safety work due to its increased mechanical properties.
STANDARD MMA WELDING
Standard MMA welding is suitable for most applications. All types of coated, rutile and basic electrodes can be used on any material in MMA welding
including steel, stainless steel and cast iron.
