3.6 Handling Instructions for RZ series Torch
(1) Remove spatters that adhered to the nozzle and tip holder before they accumulate there.
(2) For the tip and tip holder, be sure to use the DAIHEN genuine parts.
Using a tip or tip holder with enlarged hole-diameter will cause faulty power supply or swaying
weld wire, thus resulting unstable arcs or a deviation from the aiming point. To avoid that, replace
the tip or tip holder where appropriate.
(3) Provide a gas flow rate at least of 15 liters/minute.
(4) Accumulation of wire chips or dust in the liner (Located in the coaxial power cable), outlet guide,
or stop guide will cause faulty power supply to the weld wire, thus having adverse influence on
welding. To avoid that, clean such parts at regular intervals with compressed air.
(5) If weld wire gets stuck (deposited) at the tip holder end, the weld wire will buckle or be cut in the
feed roll. Continuing to feed the wire under such condition may result in faulty wire feeding or arc
shortage. To avoid that, remove the wire between the feed roll and the tip end, and then lead a
new weld wire.
(6) To lead the weld wire, unfasten the tip holder. Not doing so may cause the wire to buckle. After
the completion of leading the wire, fasten the tip holder.
(7) Cut the liner to the specified length (refer to information in 4.4 Cutting the Liner), and then fix it
with liner clamp in order to prevent the liner from moving when assembling (refer to information in
4.5 Liner Clamp Function).
Furthermore, since too long liner will disable normal pressurization of the torch, check for the liner
length according to the procedure described below. Dismount the tip holder, and then press the tip
with fingers. If the tip smoothly travels approximately by 2 mm, then liner is in its normal position.
If the tip does not smoothly travel or gets stuck to be hard to move, the liner is too long. In this
case, cut the liner to the specified length. In addition, note that too short liner may buckle in the
torch.
