Mig Welding Conector; Mig Torch; Connector For Mig Welding With A Traditional Torch; Connector For Mig Welding With A Spool Or Push-Pull Torch - Fimer TM 355 EVO Manual De Instrucciones

Hot start: Used to set the ignition current in
order to obtain a soft ignition; generally used
together with the Soft-start parameter.
Inductance: Used to modify the speed of
variation of the welding current to obtain a
harder arc (low values) or softer arc (high
values).
Water pump: Used to switch on (ON) or
switch off (OFF) the water pump unit if
present.
Please refer to the following table for the
correct welding current settings:

5. MIG WELDING CONECTOR

The connector for the welding cables comes
with a quick connect system that uses
appropriate connectors.

5.1. MIG TORCH

We would advise you to carry out regular
controls on the condition of the welding
torch; in particular, always check the nozz-
le/gas blowpipe (Fig. 4A) the wire feeder tip
(Fig. 4B), and the internal sheath of the
torch. These parts must be kept well-cleaned
and intact. If the wire stops threading correc-
tly. replace the wire guide.
N.B. Each wire and diameter corresponds
to an appropriate wire feeder tip and
sheath. Always make sure you are using
the correct type.
5.2 CONNECTOR FOR MIG WELDING
with a traditional torch
1) Connect the earth cable to the appropriate
'-' socket on the front of the device (17 of Fig 1).
Insert the connector by lining up the key with
the groove and turn in a clockwise direction
until it stops. Do not fasten too tightly!
2) Connect the torch to the appropriate
socket in the front of the device (15 di Fig 1),
turning the connector in a clockwise direction
until it stops. Do not fasten too tightly!

Warning: the machine is provided with
sockets for the MIG welding torch (Fig 4) This
accessory has a long life-time if periodical
controls of the gas nozzle and the wire-
feeder tip are carried out (Fig 4A) (Fig 4B).
These parts must be kept well-cleaned and
intact. Replace the wire guide when the wire
no longer threads correctly.
5.3 CONNECTOR FOR MIG WELDING
with a Spool or Push-Pull torch
1) Connect the earth cable to the appropriate '-'
socket. (17 of figure 1). Insert by lining up the
key with the groove and turn in a clockwise
direction until it stops. Do not fasten too tightly!
2) Connect the torch to the appropriate socket
on the front of the device (15 of Fig 1),
turning in a clockwise direction until it stops.
Do not fasten too tightly!
3) Insert the connector of the torch into the
appropriate female socket.
MIG WELDING:
Connect the pressu-
re regulator to the
cylinder, after which
attach the gas tube of
the torch to the latter.
MIG welding is usually
carried out with a con-
stant current, with a posi-
tive pole ("+ "see fig.5).
The MIG torch cable is
connected to the Euro-
connector (15 of fig.1),
whilst the earth cable
of the workpiece is con-
nected to the '-' socket
on the front (17 di fig.1).
At this stage adjust the welding current using
the potentiometer (9 of Fig.1), situated on the
front panel.
The diameter of the electrode and the wel-
ding current settings must be selected accor-
ding to the thickness of the workpiece.
