1. What polarity must be connected to the Electrode holders?

It depends on the electrodes used, must always check the packaging to which polarity must be connected to the gripper.

2. What polarity must be connected to the TIG torch?

Normally the torch for TIG welding is connected to the negative polarity of the generator.

3. Under what conditions the occurrence of the maximum power consumption?

E ‘is the measured value and indicates how much power the generator to absorb its full potential, decreases proportionally decreasing the power used in welding.

4. What is the cycle of work?

It ‘a cycle measured on a basis of 10 minutes at 40 ° C ambient temperature (in accordance with EN 60974.1) and indicate what percentage the generator works and what is left to stand for the restoration thermal regime (eg, 150 A – 40% means 4 minutes on – 6 minutes off)

5. For welding thin materials in proceedings MIG / MAG welding are low power?

To seal properly small thickness is required stable currents with small adjustment range (in increments) of tension.

6. What is meant by ecological TIG electrodes?

It ‘a range of electrodes considered environmentally friendly (without thorium) to replace the electrodes toriati, marked by the band’ Red ‘.

7. What identifies the color in TIG electrodes?

The color identifies the type and percentage of alloy added to the electrode of tungsten, for example, the green is pure tungsten, and is suitable for welding in AC (aluminum), while the blue is at 2% is lantanioed used for welding in DC.

8. TIG welders are all able to weld aluminum?

No. To be able to TIG weld aluminum must have an AC generator (altarnata with current output).

9. What does this mean thickness of plasma cutting?

The maximum thickness of plasma cutting refers to cutting of separation.

10. It ‘necessary to use gas in welding?

In welding requires the use of protective gas in processes TIG, MIG e mag.

11. Which gases are used in TIG welding for steel and stainless steel?

Preferably argon is used specifically and mixtures of pure argon – helium or helium.

12. Which gases are used in TIG welding of aluminum and its alloys?

Preferably argon is used pure.

13. Which gases are used in MIG welding aluminum and its alloys?

In the MIG welding aluminum is normally used pure argon. For special applications can be used mixtures of argon – helium.

14. Which gases are used in MAG welding steel?

In MAG welding of steel is used carbon dioxide (CO2) and mixtures of argon – CO2.

15. Which gases are used in MAG welding stainless steel?

In MAG welding of stainless steel is used a mixture of argon and oxygen.

16. Gases affect the structure and appearance of the exterior weld?

Gas would certainly protect the external appearance and the penetration of the weld bead.

17. What does torch spool gun or push-pull?

Torches spool gun and push-pull are generally used in welding of aluminum, up to 6 meters away from the source. Both torches have the ‘pistol grip and are fitted with small feeder. Spool gun is a type of torch handle with wire feeder and coil small. The adoption of this torch-passing the group of drag placed on the source of welding. Push-pull torch has the prerogative to push and pull in tandem, taking advantage of the towing and the towing-source-handle. Unlike the torch spool gun has no coil of wire, using the mail in the source of welding.

18. What does 230/400 V single-phase welder?

E ‘prepared by a welding power cable with three wires, two phases and a connection to grounding, distinguished.

19. What does welder 400 V?

E ‘prepared by a welding power cable with four wires, three phases and a connection to grounding, distinguished.

20. Who is authorized to connect to a welder to the mains?

They are qualified professionals and authorized service centers.

21. Why buy a welding machine with inverter technology?

A good drive, with values of the current stable, provides greater ease of use and better mechanical and aesthetic results of the weld bead.

22. What welders are linked to motor-generators?

All our welders electromechanical / electrodes are compatible connection of a motogeneratori.Gli inverter S1700G and SX 171C, SX 220, SX 350 have been specifically designed for use with motor-generators, all over the shipbuilding sector.

23. What does this mean welding current?

The welding current is defined by the welding that generates it, transforming it into the lower voltage values, in different forms, alternating or rectified.

24. What electrodes can be welded AC?

Alternating current welding electrodes can rutile or basic purpose-built.

25. What electrodes can weld current rectifier?

Rectified current can be performed with all types of welding electrodes.
