of twice the electrode diameter. For a better arc and current
managing capacity, the proper attack from the tip to the stone
must be longitudinal, and the tip should be slightly flat.

MIG/MAG PROCESS

The torch contact tip is the main tear and wear element in
this process, that must always be replaced according to the
continuous wire diameter that is being used. The torch nozzle
will also suffer tear and wear due to the high temperatures and
projections. The elements are manually easy-disassembled
by the plain wide passage threads systems. For an aluminium
special welding, please contact your supplier for the inner
conduct replacement (liner) to low-friction Teflon.
The mechanism of the winder has a simple operation of
the grooved rollers replacement. It is manually done by the
threaded knob that releases the pulleys, whose position can
be reversed in order to select the complementary diameter
(For ex. 0.8mm at one side and 1mm at the other).
Note: be careful not to lose the cotter pin of the winder
when releasing the pulley.
The welding wire is received on its coil and installed by
introducing it inside the winder exe and leading it to the torch
output through the traction pulleys, torch hose and torch
contact tip. The contact tip is accessible by manually twisting
the torch nozzle.
The contact tip may be removed with an open-end wrench or
pliers and must be of the same diameter as the welding wire.
Pulleys are accessible by freeing the pressure bearings that
release them. Once the wire goes through the pulleys, should
you close the pressure rollers and adjust pressure so the wire
can correctly advance and not skid nor end up destroyed.
The pulley groove must be of the same diameter as the
welding wire.
When using hollow wire, the nozzle can be removed as it is
not necessary. By doing that, you will have a wider vision and
the nozzle will not get damaged.

According to each transference mode, for example if the user
wants to work with short arc mode (thick drop, cut circuit) or
wants to work with long arc mode (thin drop, spray), you can
take action over the two detailed setting controls.
For the special settings of the MIG 280 DP see below.
SYNERGIC MODE: Press 13
Amperage: In order to make a precise general power
adjustment, it must be done through the master amperage
control, placed on the upper part of the winder frontal panel,
buttons 6 and 9. These controls are found duplicated on the
main unit.
Voltage: In order to make a precise arc characteristics
adjustment, it must be done through the master voltage
control, 9, placed on the lower part of the winder frontal panel.
When turning the control to the left, the voltage lowers and the
arc is closed while producing deposition in a high-penetration
cut circuit mode, minimum projections and a characteristic
sound. As the voltage increases, the high-performance and
