3.2 – Error messages:
During machine running several error messages can be showed at the digital display:
Er 1 – Indicates that machine is automatically switched off by thermal surcharge due to exceeding of duty cycle. Machine
must cools to reset.
Er 3 – Indicates that, when machine is switched on, the torch trigger is accidentally activated.

5 – INSTALATION / OPERATING
MIG machines must be instaled in proper places free from dust, humidity and flammable products (see pag. 39 "SAFETY
PRESCRIPTIONS FOR ARC WELDING GENERATORS).
- Before connecting the primary cable to the mains supply, voltage must be chceked (230V).
Note: Under request, different input voltages available.
- The earth connection is strongly recommended to avoid health risks.
- When conecting the gas or water hoses it is recommendable to check eventual leaks. Before open the gas tube valve be
sure that flowmeter is completely unscrewed, without gas pressure.
- The torch and the earth cable must be well tightened when connected to their plugs on machine. Equal cares must be
taken when connecting the earth clamp to workpiece in order to mantain the good quality of the welding.

When positioning the wire spool, it is necessary to verify the correct positioning of its hole (2) on the spindle (4) of the wheel
(3) in order to mantain operational the breakage system.
- The wire feeder rolls (8) and the tip of the torch (9) must correspond to the wire diameter.
The wire must be manually conducted a few centimeters through the rolls (8) and the wire guide (6). After this, close the
traction levers (9) verifying that the wire (10) rests well positioned on the roll rend.
The roll pressure regulation must be completed when the motor is runing (the wire must flow without sliding). This pressure
should be reduced to the minimum in order to prevent wire deformations by crushing.
- After this, the wire coil breakage system must be regulated, actuating on the respective screw (1). The rotation movement
of the wire coil must stops at the same time as the motor.
- Switch on the machine positioning the main switch on ON position and press the torch trigger until the wire appears
outside the torch tip (9-fig.3). If necessary, unscrew the tip torch and straight torch cable.
During welding, regulate the gas flow (between 6 and 10 lts/min).
- Machine is ready to weld. If necessary, before start the welding job, test welding parameters on a separated sample.
Before welding, analyze personal and environmental security conditions according to chapter one (Safety presciptions).
