 Before every welding work, check carefully whether the welder’s correction & earth wire are correct

and reliable.

 Inflammable or explosive materials are prohibited in the welding areas.

 To ensure the air flow in the welding areas, as the welding smoke is bad for the health.

 * Isolate the arc light to protect others

 Irrelevant persons are not allowed to enter into the welding area. Forbid to adjust or move the welders

in the welding time.

 Welders have strong electromagnetism and electric frequency disturbs. Do not let near the persons

with heart pacemaker or easily affected by electromagnetism and electric frequency.

 Do not press, pile or stress the welding wires by any apparatus. Do not bend the welding wires into

very small angle, otherwise it would hurt the inside wires to cause the hidden troubles.

 Do not touch any output joints with electric in the welding time.

 Forbid to use the welder for the pipe ice-out.

 Deliver the welder by forking machine or with base. Forbid to move by handles above the welders.

 Pay high attention on the rated duty cycle of welders to avoid the overload.

Safety protection in the welder’s installed and used places

 Protection on persons and welders under areas, where there are items dropped down.

 Dusts, Acid, Causticity airs or materials contents in the welding area air to be lower than the relevant

standards (except for these caused by the welding)

 Inflammable, explosive or other dangerous materials are prohibited in the welding areas.

 The welders should be installed in these places, without direct sunshine, rain drench, lower humidity,

-10

+40℃.

 50cm space to be ensured around the welders for the nice airness.

 Metal eyewinker not allowed into the welders.

 No strong shake allowed in the welding area.

 Protect the welder from the dumpage, when the welders put in the over 10° declining plane.

 Choose the installation area to avoid any disturbs to other electromagnetic equipments, when the

welders used.

 Block the wind, when the air protection welding used.

Safety Check

Operator should check below procedures before every welding job:

 Make sure the welder’s earth protection is reliably connected.

 Make sure the welder’s input, output wires is fine, not exposed outside.

 After the fixing of the welders, make safety check each six months by qualified persons.

 Make sure no spare parts not tightened inside the welder and clear the dusts.

 Check the spare parts on the welder panel to ensure the welder could work well.

 Check the welding wires whether aged for used

 Check the input wires whether damaged or not. If damaged, improve it.
