Setup For Welding - Smarter tools ARC-100S Manual Del Usario

The welding equipment should be routinely maintained according to the
manufacturer's recommendations. All access and service doors and covers
should be closed and properly fastened when the welding equipment is in
operation. The welding equipment should not be modified in any way except
for those changes and adjustments covered in the manufacturer's instructions.
In particular, the spark gaps of arc striking and stabilizing devices should be
adjusted and maintained according to the manufacturer's recommendation.
3. Welding Cables
The welding cables should be kept as short as possible and should be
positioned close together, running at or close to the floor level.
4. Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it
should be considered. However, metallic components bonded to the work
piece will increase the risk that the operator could receive a shock by touching
the metallic components and the electrode at the same time. The operator
should be insulated from all such bonded metallic components.
5. Earthing of the Work Piece
Where the work piece is not bonded to earth for electrical safety, nor
connected to earth because of its size and position, e.g. ship's hull or building
steelwork, a connection bonding the work piece to earth may reduce emissions
in some, but not all instances. Care should be taken to prevent the earthing of
the work piece increasing the risk of injury to users, or damage to other
electrical equipment. Where necessary, the connection of the work piece to
earth should be made by direct connection to the work piece, but in some
countries where direct connection is not permitted, the bonding should be
achieved by suitable capacitance, selected according to national regulations.
6. Screening and Shielding
Selective screening and shielding of other cables and equipment in the
surrounding area may alleviate problems of interference. Screening the entire
welding installation may be considered for special applications.

3.5 Setup for Welding

Conventional operating procedures apply when using the Welding Power Source,
i.e. connect work lead directly to work piece and electrode lead is used to hold
electrode. Wide safety margins provided by the design ensure that the Welding
Power Source will withstand short-term overload without adverse effects. The
welding current range values should be used as a guide only. Current delivered
