1.3. OPERATION SAFETY
Please study these Operation safety instructions and respect them when installing, operating and
servicing the machine.
Welding arc and spatters
Welding arc hurts unprotected eyes. Be careful also with reecting arc ash. Welding arc and
spatter burn unprotected skin. Use safety gloves and protective clothing.
Danger for re or explosion
Pay attention to re safety regulations. Remove ammable or explosive materials from welding
place. Always reserve sufcient re-ghting equipment on welding place. Be prepared for

2.1. CONNECTING TTC-TORCH
Connect torch (and extension parts) according to welding machine’s operation instructions.
Tighten adaptors of torch carefully in order to avoid heating of adaptors, contact disturbances,
mechanical damage and water or gas leakage.
Check by connection of liquid hoses that there are no dirt, metal powder or other
wastes. Wastes may cause blocking in liquid circulation, throughburning of torch
or stopping or breaking of pump.
Connect liquid hoses of torch according to operation instruction of the cooling liquid circulation
unit. (They are fastened to pipe chassis.) Fix liquid hoses (torch – cooling liquid circulation unit)
in such a way that those having red code always are connected to corresponding red counter
connectors and the blue ones respectively to blue counter connectors.
hazards in special welding jobs, eg. for the danger of re or explosion when welding container
type work pieces. Note! Fire can break out from sparks even several hours after the welding
work has been nished!
Mains voltage
Never take welding machine inside a work piece (eg. container or truck). Do not place welding
machine on a wet surface. Always check cables before operating the machine. Change defected
cables without delay. Defected cables may cause an injury or set out a re. Connection cable
must not be compressed, it must not touch sharp edges or hot work pieces.
Welding power circuit
Isolate yourself by using proper protective clothing, do not wear wet clothing. Never work
on a wet surface or use defected cables. Do not put TIG-torch or welding cables on welding
machine or on other electric equipment. Do not press TIG-torch switch, if the gun is not directed
towards a work piece.
Welding fumes
Take care that there is sufcient ventilation during welding. Take special safety precautions
when welding metals which contain lead, cadmium, zinc, mercury or beryllium.
If connections cross, cooling liquid is circulating in wrong direction in torch, and
torch handle and neck body might be considerably heatened.
2.2. SWITCH AND REGULATOR OPERATIONS
The TTC torches are equipped with ON/OFF switch. Operation of switch in 2-functions,
4-functions and Minilog positions is described in operation instructions of the welding machine.
TTC torches can be equipped with RTC 10 or RTC 20 torch regulators which are available as
assessory. Regulators can be assembled in place of the original start-switch.

Besides the start-switch there is a potentiometer for controlling the welding current.

Assembly instruction is delivered with the regulators.
2.3. ADJUSTMENT OF TORCH BODY AND GRIPS
You can draw the torch neck outwards from inside the handle in approx. 30 mm length in order
to grow reach or to minimize heat radiation to welder’s hand. You can also twist the torch
body 360° in regard of the handle. Twisting of neck makes the length adjustment easier. Before
starting to weld make sure that the parts being exposed to voltage at the back end of the neck
body are not visible.
You can without tools move or twist grips on the lower surface of the handle into such position
you like that you can get a steady hold on the torch. You can also easily remove one or both of
the grips through the front end of the handle.

2.4. CHOICE OF ELECTRODE SIZE AND FLOW AMOUNT
OF SHIELDING GAS
Electrode size and shielding gas ow are dened by welding current level. The most usual
shielding gas for TIG welding is argon.

2.4.1. Electrode choice according to base material to be welded
Delivery length of electrodes is 175 mm.
Data in table are given only as a guide.
2.5. SHARPENING OF ELECTRODE
2.5.1. D.C. welding
In D.C. welding the tip of electrode is sharpened into cone shape in order to get a steady arc and
to concentrate heat energy on welding point. Size of sharpening angle has an effect on width of
welding run and depth of penetration. Ratio of sharpening length to electrode diameter:

8 – TTC 130, TTC 130F, TTC 160, TTC 160S, TTC 220, TTC 200W,
TTC 250W, TTC 250WS/0109 © COPYRIGHT KEMPPI OY
Suitable sharpening length depends on welding current which is used most often.
Low currents
Mean currents
High currents
Always make sharpening grinding lengthwise of electrode.
2.5.2. A.C. welding
In A.C. welding the temperature of electrode tip rises a little more higher than melting point of
tungsten and brings about formation of ball-shaped curved surface. On basis of tip formation
and arc behaviour you can determine suitability of welding current for used electrode size and
material.
A Low welding current or big electrode size. Arc will be unsteady and is not directed
on welding object.
B Suitable current.
C Too high current or too small electrode diameter.
You can speed up the tip formation by electrode change e.g. with following:
- Adjust welding current a little higher than usually.
- Burn arc to waste piece by keeping the torch in vertical position.
- Arc is extinguished immediately after the electrode tip has become round.
- Current is reduced to be suitable for work and welding is started.
You can grind the electrode partly at its tip at which the tip will be better ball-shaped and
the arc more steady.

2.6. PROJECTION OF ELECTRODE
Suitable distance of electrode tip from front edge of gas nozzle depends among others on electrode
diameter and current type.
Formation of weld preparation has a considerable effect on suitable electrode projection. E.g. when
you are welding the external angle, you should use a clearly smaller projection than in llet weld.
Tighten the electrode with reasonable force. Too strong a tightening may damage tightening parts
of electrode.
3. MAINTENANCE
Due to high temperatures and wear the welding end of TIG torch requires most maintenance, but
also condition of other parts should be checked regularly.
Welding end
Check that…
- All insulations of welding end are undamaged and at their place.
- Gas nozzle is undamaged and suitable for work.
- Flow of shielding gas is free and even.
- Electrode is undamaged. Use electrode size and tip sharpening angle which is suitable for
welding case. Make sharpening grinding lengthwise of electrode.
- Fastening parts of electrode are undamaged and electrode is fastened tightly at its place.
Torch cable
Check that…
- Insulations of handle and torch cable are undamaged.
- There are no sharp bends in torch cable.
Replace damaged parts immediately by new ones.
Frequent bending of neck body of torch may cause damage of gas
or liquid channels.
Length adjustment of neck body doesn’t work on bent neck.

4. OPERATION DISTURBANCES
4.1. THE MOST USUAL OPERATION DISTURBANCES ARE
AS FOLLOWS:
Arc is not ignited:
- Cable is loose or there is a bad connection.
- Electrode of torch is highly oxidized (grey). Sharpen again lengthwise. Check that
post gas time is long enough. Check ignition by using pre-gas e.g. by 4-function
operation of torch.
- There are impurities in shielding gas (moisture, air).
- Protective hose or another insulation of torch is broken and ignition spark is “esca-
ping” from elsewhere than from electrode of torch.
- Torch is wet.
- At low current is used too big or blunt electrode.
Gas shielding is bad (weld pool “is boiling”, electrode will be oxidized)
- There are impurities in shielding gas (moisture, air).
- There are impurities in base material (rust, base coat, grease).
- On gas nozzle or housing of tightening bushing has stuck “spatter”.
- Net of gas lens is damaged.
- There is too much draught at welding place.
- Note! With gas lens equipment you get a more balanced gas ow than with normal
gas nozzle equipment.
