All work must be carried out by trained personnel well--acquainted with the operation of the welding
equipment. Incorrect operation of the equipment may lead to hazardous situations which can result
in injury to the operator and damage to the equipment.
1. Anyone who uses the welding equipment must be familiar with:
S its operation
S location of emergency stops
S its function
S relevant safety precautions
S welding
2. The operator must ensure that:
S no unauthorised person is stationed within the working area of the equipment when it is
started up.
S no--one is unprotected when the arc is struck
3. The workplace must:
S be suitable for the purpose
S be free from draughts
4. Personal safety equipment
S Always wear recommended personal safety equipment, such as safety glasses, flame--proof
clothing, safety gloves.
S Do not wear loose--fitting items, such as scarves, bracelets, rings, etc., which could become
trapped or cause burns.
5. General precautions
S Make sure the return cable is connected secure ly.
S Work on high voltage equipment may only be carried out by a qualified electrician.
S Appropriate fire extinquishing equipment must be clearly marked and close at hand.
S Lubrication and maintenance must not be carrie d out on the equipment during operation.
GB
WARNING
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND
OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR
EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE BASED ON MANU--
FACTURER’S HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to keep fumes and gases from
your breathing zone and the general area.
ARC RAYS -- Can injure eyes an d burn skin
S Protect your eyes and body. Use the correct welding screen and filter lens
and wear protective clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no
inflammable m aterials nearby.
NOISE -- Excessive no ise can damage h earing
S Protect your ears. Use ear defenders or other hearing protection.

2 INTRODUCTION
2.1 General
MTT 1200 is designed for continuous MIG/MAG welding with high requirements for
function and reliability.
The very effective cooling principle is integrated both in the contact tubes and in the
external cooling jacket. The coolant passes with a whirling motion through the parts
very close to the contact nozzle and the gas nozzle.
For easy installation the welding cable and the gas and coolant hoses are connected
at the rear of the contact device, which also protects the cables and hoses from
undesired heat and radiation from the welding.
The contact device can easily be connected to different wire feed units and wire feed
systems by way of special adapters.
2.2 Definitions

during the welding.

Caution:
Have you read and understood the safety information ?
You must not operate the machine beforehand !
General safety regulations for the handling of the equipment can be found on
page 44. Read through before you start using the equipment!
4.2 Before welding
S Make sure the water cooling functions.
S Make sure the gas cup is free of welding spatter.
S Adjust the electrode stick--out of contact tube 2 (*) using screw (2).
S Adjust the electrode distance using screw (1).
S Make sure the contact tubes are fixed. If not, tighten with the screws ( 3).

5 MAINTENANCE
5.1 General
The actual safety regulations must be followed precisely when
measures with regard to the In stallation / Operation and
Maintenance are taken!
Note:
All warranty undertakings given by the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
5.2 As necessary
S Clean the contact nozzle and the gas cap of welding spatter.
Note that the gas lense is fragile therefore clean carefully.
N.B.
The gas cap protects the centre sleeve being burnt through by the heat and
radiation from the welding.
Check the condition of the gas cap often and replace as necessary.
Do not weld if the gas cap is missing or in bad condition.
S Check the condition of the wear insert and blow it clean using compressed air.
Select a contact nozzle of the correct dimension according to the wire, see the
table on page 52.
S Check the contact nozzle and replace if deformed or worn.
