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 reflecting arc flash. Welding arc and
spatter burn unprotected skin. Use safety gloves and protective clothing.
danger for fire or explosion
Pay attention to fire safety regulations. Remove flammable or explosive materials from
welding place. Always reserve sufficient fire-fighting equipment on welding place. Be
prepared for hazards in special welding jobs, eg. for the danger of fire or explosion when
welding container type work pieces. Note! Fire can break out from sparks even several hours
after the welding work has been finished!
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 fire.
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 sufficient ventilation during welding. Take special safety precautions
when welding metals which contain lead, cadmium, zinc, mercury or beryllium.

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.
NOTE! 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.
NOTE! 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.
