of the material in millimeters, and graphical thickening or thinning of the material:

Depending on the thickness of the material will also appear ATC symbol. ATC is an advanced thermal control

function, activated when welding thin materials to a thickness of 1.5 mm.

ATC function stabilizes the arc and reduces the peak value of the welding current by reducing the amount of heat transferred to

the material. As a result, greatly facilitates the welding of thin elements and results in smaller deformations of the material, and

less overheating of the narrow heat affected zone.

In turn, the lower knob is used to weld the upregulation shape (arc length) -9 ÷ 9. The display will change

the shape of the graphic indication of the weld:

The shape of the convex is the low thermal load in low merging the material. Shape intermediate the

recommended setting the average fusing the material. The shape of the concave is a high thermal load

and at a high merging the material.

7.5 welding parameters for MIG / MAG

The basic parameters of the MIG / MAG: welding current and wire feed speed of the

electrode. Increase welding current increases penetration (penetration depth) and elongation of the

arc. Increasing the speed of a wire electrode causes the handle is biased upwardly from the parts to

be welded. This is due to too small a welding current. When the wire feed speed of the electrode is

too small or the welding current is too high at the end of the electrode wire formed large droplets.

Excessive spatter prove too low welding current or too high feeding speed of the electrode wire.

When welding positions and pułapowych wall, you can reduce the welding current, the performance

of joint filler to achieve a smooth face, you can increase the welding current.

7.6 Practical recommendations MIG / MAG welding.

Butt welds in the flat position must be carried out using "push" for thin components and

technology "pull" for items thicker. Butt welds in vertical position for thin elements should be done

from top to bottom. Fillet welds in position nabocznej should be carried out using "push", but with an

additional tilt the torch in a plane perpendicular to the direction of welding. In the case of filling the

wide grooves in the flat position

or the vertical end of the handle must be performed

lateral swinging movements. During welding, the welding gun should be conducted at a right angle

relative to the parts to be welded -If high helix angle may result in sucking air into the liquid metal

angle (from the vertical holder should be ≤ 10 °). Long arc welding reduces the depth of penetration -

the seam is wide and flat, and is accompanied by increased weld spatter.

Short arc welding (with the same current density) increase the depth of penetration - the weld is narrower,

and the spatter material becomes smaller. The welding speed is a parameter output at a given current

intensity and arc voltage, and maintaining the correct shape of the weld bead, and when the welding speed

may even be slightly changed, change the current or the arc voltage. The increase welding speed makes the

weld is narrower and decreases the depth of penetration, and with further increase in the face of flooding

occur. The largest welding speed, without undercuts, can be obtained by increasing the stick electrodes and

the inclination of the object up and down or tilt in the direction of the welding torch. Small welding speeds

cause that increases the depth of penetration, face width and height of the riser.

Excessive lengthening or shortening the arc can

cause unstable arc glow and poor weld quality.

L1, L2 - arc length

The depth of penetration is also significantly impact

the direction of welding - carrying the torch.

H1, H2 - the depth of penetration

Due to the nature of the shielding gas and the electrical parameters of the welding process (voltage

and current) There are three ways to change the physical state of the metal in the arc welding:

GRUBOKROPLOWY - used for MIG / MAG

low current densities and long arc

- not recommended in forced positions

SPRAY

- used in the MAG gas mixtures

- not recommended in forced positions

Short circuit

- used in MAG welding with short arc

- recommended for welding parts of small thickness

and forced positions

The protective gas guards determine the efficiency of the welding area, but also of a process for transferring the

metal in the arc, the welding speed and the shape of the weld. Inert gases argon and helium, although perfectly

protect the molten weld metal against access of air, are not appropriate for all applications of MIG-MAG welding. By

mixing in the appropriate proportions of helium or argon and a chemically active gas obtained by changing the

nature of metal transfer the arc to increase arc stability and there is possibility to influence on metallurgical

processes in the weld seam. At the same time it is possible to significantly reduce or completely eliminate splash.
