• Avoid performing welding / cutting operations in such enclosed areas as much as possible.

• Take all necessary precautions when moving the machine. The areas where the machine to be

transported, parts to be used in transportation and the physical conditions and health of the

person carrying out the transportation works should be suitable for the transportation process.

• Some machines are extremely heavy; therefore, make sure that the necessary environmental

safety measures are taken when changing their places.

• If the machine is to be used on a platform, it must be checked that this platform has suitable load

bearing limits.

• If it is to be transported by means of a haulage vehicle (transport trolley, forklift etc.), make sure

of the durableness of the vehicle, and the connection points (carrying suspenders, straps, bolts,

nuts, wheels, etc.) that connect the machine to this vehicle.

• If the machine will be carried manually, make sure the durableness of the machine apparatuses

(carrying suspenders, straps, etc.) and connections.

• Observe the International Labor Organization’s rules on carriage weights and the transport

regulations in force in your country in order to ensure the necessary transport conditions.

2.5 Connections for Plasma Cutting

Be careful during the cutting process and wear appropriate protective clothing and gloves.

2.5.1 Gas Connections

• If the gas source is in the workshop or gas cylinder, a gas regulator should be used and this regulator should be

able to supply gas to the air inlet on the machine.

• If a gas cylinder is used, secure the gas cylinder to prevent it from tipping over.

• In order to work safely and achieve the best results, use a regulator that complies with standards and make sure

the gas supply quality is up to the standards. Gas supply quality will affect cutting performance and

consumption quality.

• Protect the gas line from contaminants such as oil, dust, etc.

• Keep the gas cylinder valve open for a while to allow possible sediment and particles to be discharged.

• Connect the gas regulator to the gas cylinder, make sure that the screw thread on the gas outlet of the gas

cylinder and the nut of the regulator overlap.

• Connect one end of the tube hose to the gas regulator and the other end to the gas inlet at the back of the

machine and open the gas cylinder valve.

It works with dry contact structure. The automation unit sends a warning to the plasma machine to operate

via the dry contact and the plasma creates a pilot arc. After the plasma machine creates a pilot arc, it sends a

warning to the automation unit with the dry contact structure. When the machine starts the cutting process,

it reports the plasma arc voltage for the automation interface to adjust the height.

after the gap, it is necessary to press and release the trigger again and start the pilot arc in

order to continue cutting. Grid cutting mode was created to be used on grid type materials.

A pilot arc occurs as soon as you press the torch trigger in the grid cutting and the material

is cut. It cuts the pilot arc when the gap is reached, and activates the pilot arc when it arrives

to the material part again. This cycle continues until you release the trigger.

The cutting process ends as soon as you release the trigger.

Pilot arc occurs as soon as you press the trigger in this mode. You can take your hand off the

trigger and continue the cutting process once you have started the cutting process.
