OPERATION SAFETY
Never watch the arc without a face shield designed for arc welding!
The arc damages unprotected eyes!
The arc burns unprotected skin!
Be careful for reflecting radiation of arc!
Protect yourself and the surroundings against the arc and hot spray!
Dont use power source for melting of frozen pipes!
Remember general fire safety!
Pay attention to the fire safety regulations. Welding is always classified as a fire risk operation.
Welding where there is flammable or explosive material is strictly forbidden.
If it is essential to weld in such an area remove inflammable material from the immediate vicinity of the
welding site.
Fire extinguishers must always be on site where welding is taking place.
Note! Sparks may cause fire many hours after completion of welding.
Watch out for the mains voltage!
Take care of the cables - the connection cable must not be compressed, touch sharp edges or hot work pieces.
Faulty cables are always a fire risk and highly dangerous.
Do not locate the welding machine on wet surfaces.
Do not take the welding machine inside the work piece (i.E. In containers, cars etc.)
Ensure that neither you nor gas bottles or electrical equipment are in contact with live wires or connections!
Do not use faulty welding cables.
Isolate yourself by using dry and not worn out protective clothes.
Do not weld on wet ground.
Do not place the TIG torch or the welding cables on the power source or other electrical equipment.
Be careful of TIG ignition pulse voltage!
Dont press on torch switch, if the torch is not directed towards work piece.
Dont use wet TIG torch. Do not use damaged TIG torch.
Watch out for the welding fumes!
Ensure that there is sufficient ventilation.
Follow special safety precautions when you weld metals which contain lead, cadmium, zinc, mercury or
beryllium.
Note the danger caused by special welding jobs!
Watch out for the fire and explosion danger when welding container type work pieces.

1. GENERAL
Mastertig AC/DC is a power source for TIG /MMA welding suitable for AC and DC welding and designed
for demanding professional use. The power source is an inverter, which is formed with IGB transistors.
The power source is available in three sizes, 160 A, 250 A and 350 A. The 250 A power source comes in
two separate versions for gas-cooled torches and for water-cooled torches. Three different exchangea-
ble panel versions are available for the power source: a basic panel, a MINILOG panel and a pulse panel.

2.2 Siting the machine
When siting the machine, the following have to be
considered:
Site the machine on a fixed dry base, which does not
cause dust etc. into the suction air of cooling.
Make sure that the machine is placed away from
the line of particle spray from grinding tools.
Ensure the free circulation of the cooling air. Make
sure that there is at least a 20cm free distance
both in front of and at the rear of the machine for
the circulation of the cooling air.
Protect the machine against heavy rain and in hot
circumstances against direct sunshine.
2.3 Start of installation
Mastertig AC/DC 2500 and -2500W: Check first that the
mains voltage change-over switch is in right position.
If it is needed to change mains cable, do it before
mounting to the wheel barrow T120. Otherwise you
bossibly have to dismount the machine.
Before connecting the machine to the mains supply,
one of the three panels, the ACDC panel, the ACDC
minilog or the ACDC pulse panel, has to be installed.
Installation instructions 4283280 are in the package of
the panel.
2500, 2500W, 3500W
2.4 Connecting the machine to the mains
supply
The installation or replacement of the mains
cable and the plug may be carried out only by
an authorized electric shop or electrician.
Mastertig AC/DC 1600
The Machine is delivered with a mains cable with a
schuko plug for connection to a mains supply of 230 V.
To be noted when replacing the mains cable:
The lifting handles, cover and the right-hand-side plate
have to be opened. The cable in brought to the machine
through the inlet ring on the rear panel and fastened
with a cable clamp. The phase lead of the cable are
coupled to connector L, the blue to the connector of
the N lead and the yellow-green to the connector of
the protective grounding lead .
Mastertig AC/DC 2500, -2500W and -3500W
The machine is delivered with a 5m mains cable
(4×2.5mm
2
) without a plug. Mains cable is suitable
for all mains voltages with recommended fuse size
(please look at Technical data table). 4×6mm
2
cable
can be assembled to the machine, if local regulations
are requiring it.
If you use greater fuse size than recommended
big short circuit current can cause extra dam-
age in case of failure.
Mastertig AC/DC 2500, -2500W
Before connecting the machine to the mains supply,
make sure that the voltage change-over switch of the
machine is turned to the position corresponding to the
mains supply voltage (230 / 400 / 460V).
When replacing the mains cable, note the following:
The lifting handles, cover and right-hand-side plate of
the machine have to be opened. The cable is brought
to the machine through the inlet right on the rear panel
and fastened with a cable clight. The phase leads of
the cable are coupled to connectors L1, L2 and L3; the
yellow-green is coupled to the connector of the protec-
tive grounding lead .
