Generator use

This welding machine can be used at all mains

supplies providing sine-shaped current and voltage

and not exceeding the approved voltage tolerances

stated in the technical data. Motorised generators

observing the above can be used as mains supply.

Consult your supplier of generator prior to connecting

your welding machine. MIGATRONIC recommends

use of a generator with electronic regulator and supply

of minimum 1.5 x the maximum kVA consumption of

the welding machine. The guarantee does not cover

damage caused by incorrect or poor mains supply.

How to connect the gas

Connect The gas hose, which comes from the

intermediary cable, to a gas supply with pressure

regulator (2-6 bar).

(Note: Some types of pressure regulators require an

output pressure of more than 2 bar to function

optimally).

Assembly of the earth cable

The earth cable (negative pole) is fitted to the

inductance outlet wanted (depending on the

dimension of the welding wire). (Pos. 2-3).

Wire feeding

The wire roll combination to the chosen wire diameter

can be seen from the figure page 46. The machine is

delivered with one set of wire rolls etc. as standard.

Other sizes can be delivered. Only parts of the same

colour can be fitted together.

Adjustment of wire brake

The wire brake must ensure that the wire reel brakes

sufficiently quickly when welding stops. The required

brake force is depending on the weight of the wire reel

and the maximum wire feed speed. A brake torque of

1.5-2.0 Nm will be satisfactory for most applications.

Adjustment:

Dismount the control knob by placing a thin screw

driver behind the knob and thereafter pull it out

Adjust the wire brake by fastening or loosening the

self-locking nut on the axle of the wire hub

Remount the knob by pressing it back into the

groove.
