PT100 Plasma Hand Torch

The PT100 plasma torch supplied has the ‘euro style’ power/gas connecon, pilot cable and switch pins

connecons.

All Jasic plasma cung systems and torches supplied incorporate a safety circuit to prevent operator injury when

changing consumables etc. This is a simple ring circuit that breaks the electrical torch switching as soon as the

retaining cap is removed prevenng machine operaon. Without such a protecon circuit as previously menoned

the open circuit voltage could be as high as 350V DC at the torch head.

The torch head encompasses a full set of consumables as shown right, these consumables are made

up of a cooling tube, torch electrode, swirl ring for gas distribuon, cung p, retaining cap and if

required a stand o device to ensure the same distance between p and material being cut.

Fing the PT100 plasma torch

On the Jasic Cut 61 plasma machine, the below torch ng instrucons

will need to be observed.

• Locate plasma torch plug into euro connector socket as shown in

image 1 below

• Push the torch (image 1) whilst at the same me rotate the locking

nut on torch clockwise unl fully connected and ght as in image 2

Plasma Cung Safe Working Pracce

Safety glasses must be worn at all times in addition to welding mask Long and loose hair must be contained

Oil free leather gloves and spats must be worn Sturdy footwear with rubber soles must be worn

Close fitting/protective clothing to cover arms and legs must be worn A welding mask with shade number 11 protective filters must be worn

Respiratory protection devices may be required Hearing protection may be required when cutting thick material

PRE-OPERATIONAL SAFETY CHECKS

• Locate and ensure you are familiar with all machine operaons and controls.

• Ensure material to be cut poses no hazard. Consult the manufacturers' Material Safety Data Sheets (MSDS) for specic technical data and precauonary measures for any materials or

coangs on materials cut with this equipment.

• Check workspaces and walkways to ensure no slip/trip hazards are present, ensure the work leads and hoses do not create a trip hazard.

• Ensure the work area is clean and clear of grease, oil and any ammable materials.

• Keep the equipment, work area and your gloves dry to avoid electric shocks.

• Ensure the gloves, handpiece and work leads are in good condion.

• Ensure other people are protected from ashes by closing the curtain to the welding bay or erecng screens.

• Start the fume extracon unit before beginning cung operaon. Ensure machine is used in a well-venlated area if not used in a welding bay.

OPERATIONAL SAFETY CHECKS

• Ensure machine is correctly set up for current and airow.

• Ensure work return earth cables make rm contact to provide a good electrical connecon.

ENDING OPERATIONS AND CLEANING UP

• Switch o the machine and fume extracon unit when work completed.

• Turn o the air supply and hang up handpiece, hose and welding cables.

• Leave the work area in a safe, clean and dy state.

DON’T

• Do not use faulty equipment. Immediately report suspect equipment.

• Do not weld or cut containers that have held combusble liquids or gases.

• Do not heat or cut metals coated with or containing materials that emit toxic fumes, unless coang is removed from the work surface.

• Never leave the machine running unaended.

This safety page does not necessarily cover all possible hazards associated with plasma equipment safety and should be used in conjuncon with the operang manual along

with other references such as risk assessments. It is designed as a reminder to users prior to equipment use and as a guide to be used to compliment operator training.

POTENTIAL HAZARDS AND INJURIES

 Electric shock

 Noise

 Body burns

 Compressed air

 Radiaon burns

 Fumes

 Noxious gas

 Flying sparks and falling slag

Wilkinson Star Technical

General Plasma Cung Informaon

Before starting any welding or cutting activity ensure that you have suitable eye protection and

protective clothing. Also take the necessary steps to protect any persons within the welding area.

Notes for cung operaon

 Do not touch the hot workpiece with bare hands to avoid burning.

 It is recommended not to ignite the arc in the air if not necessary, for it will shorten the lifespan of the electrode and nozzle of the torch.

 It is recommended to iniate the cung from the edge of the workpiece unless penetraon is needed.

 Ensure spaer comes from the boom of workpiece while cung. If spaer comes upwards from the top of workpiece, it indicates that the

workpiece has not been fully cut through. This could be due to not enough power or the cung torch is moved too fast.

 For cung a round or shaped piece or to meet precise cung requirement, a stencil board or other tools are needed.

 It is recommended to pull the cung torch while cung.

 Keep the nozzle of the cung torch upright over the workpiece and check if the arc is moving with the cung line. Do not bend the cable too

much, step on or press upon the cable to avoid restricng the air ow. The cung torch may be burned if the air ow is too low. Keep the cung

cable away from sharp edges.

 When the workpiece is nearly cut o, slow down the cung speed and release the torch trigger to stop cung.

 Check the torch consumables frequently to prolong the life.

 Always ensure the correct consumables are ed in the torch. Incorrect items may cause damage to the torch or machine.

 It is recommended that a torch of maximum length of 6 metres is used. If the torch cable is too long, the performance of this cung machine

such as arc ignion will possibly be aected due to the fact that the inner resistance of the cable will reduce the output voltage.

Please Note:

• Your air supply must be free of moisture, water, oil or any other contaminants. Excessive water or oil may cause double arcing, excessive

electrode/p wear or even torch head failure. Contaminants will also cause poor cut quality.

• When starng the arc, ensure you keep the pilot arc me to a minimum to avoid excessive wear on the cung p.

• Do not overghten the electrode when ng a new set of consumables. Over ghtening may cause damage to the internal torch head thread

so that the cung p will not seat correctly.

• Only use the supplied or recommended ’O’ ring lubricant or grease for your plasma torch head, using the wrong lubricant that cannot

withstand high temperatures could cause damage to the plasma torch head.

Stand-O Cung

The stand-o cung technique is the process of holding the p of the torch

between 3-4mm from the workpiece to achieve the opmum cut.

Stand-o cung requires a cung p that you need to ensure that the plasma

machines output amperage is matched to the amperage with the p.

Depending on the applicaon the operator may choose to hold the torch ‘free

hand’ away from the plate or could choose to use a stand-o guide to help hold the

torch away from the plate at a xed height, also available are roller guides and

circle cung guide kits which can be very helpful in creang the cuts you want.

To begin cung you would place the torch above the work piece of about 3-4mm,

and begin drawing the p across the workpiece.

You should always start with the torch placed at farthest point from you and then

cut by pulling the torch towards you.

Make sure to keep the torch upright to the material being cut throughout the

cung process.

As you are cung ensure you maintain a smooth and consistent travel speed to

make a clean and precise cut.

There are 3 main reasons why plasma machine operators prefer to use the stand-o

technique rather than drag p cung

 It allows for a smoother movement of the torch above the material being cut

without any part of the torch touching the material.

 You can comfortably stand the torch while making the contouring process or

following a certain paern.

 Because the cung p is not touching the material, this helps to prevent any

blowback of molten material.
