SAFETY PRECAUTIONS
Operation and maintenance involves potential hazards. All operators and
personnel should be alerted to possible hazards and precautions should
be taken to prevent possible injury.
Electrical safety
Maintenance
Individual safety
Machine：
﹡
The counter, safety device against excess current and electrical installation,
are compatible with its maximum power and its main voltage.
﹡
The connection, single-phase or three-phase, is possible on a stand
compatible with the plug of its cable link.
﹡
If the cable is connected with the electrical network, the earth, must never be
cut by the protection device against electrical shocks.
Work Place：
﹡
Be very careful to avoid contact between metal part and phase conductor
and the neutral of electric network.
﹡
Electrical messes of different electrical machine and apparatus are
connected between themselves and with the terminal of earth neutral wire.
Interventions：
﹡
Before control and repair, see the apparatus is switched off and insulated.
﹡
Connection with fixed installation cable is impossible.
﹡
It’s on “STOP” and connection is impossible.
﹡
Some apparatus are provided with starting circuit HT HF (with a plate). Never
enter into the corresponding switch cupboard.
﹡
Only qualified persons are authorized fo
r intervention concerning
electrical
installation.
﹡
Often check the insulation and connection good state of apparatus and
electrical accessories: taps, appliance cords, coatings, switch, extension
cords, etc.
﹡
Maintenance and repair of insulating coatings operations are very important.
﹡
Do repair with a specialist or better replace defective accessories.
﹡
Check regularly the right adjustment and the non-heating of electrical
connections.
﹡
The operator must be dressed and protected in relation with his work.
﹡
Avoid contacting metal parts connected or accidentally connected.
﹡

1.1 INTRODUCTION
Instruction
Main features
﹡ Welding positioned is normally used in the rotating and welding of the pipe or
round work pieces.
﹡ It can be applied on all kinds of welding: SMAW, MIG, TIG, Plasma, etc.
﹡ It can adopt different fixture to get the welding effects you require.
﹡ The table can be tilted for 0~135º, which is convenient for all angles of the pipe
welding or for adjusting welding angles. (It can adopt either manual or electrical
operation.)
﹡ The table has a through hole of 25 mm, which is convenient for the long pipe
welding or the purge shielding gas.
﹡ On the table, there are 4T- slots, suitable for all kinds of fixtures and grippers.
﹡ Ground current conduction：200Amps (400Amps option).
﹡ All units are high frequency protected.
