Tig Welding - Cebora 254-bi-welder Manual De Instrucciones

• Turn the machine on using the switch (F).
• Adjust the current based on the diameter of the electrode,
the welding position and the type of joint to be made. Always
remember to shut off the machine and remove the elec-
trode from the clamp after welding.

3.3 TIG WELDING

• This welding machine is suitable for welding the following
materials using the TIG procedure: stainless steel, iron, cop-
per.
• Make sure that the switch (F) is in position 0.
• Connect the mass cable connector to the positive pole (+)
of the welding machine, and the clamp to the workpiece as
close as possible to the welding point.
• Use the torch type T150 (art. 1567.01) and connect the
power connector to the negative pole (-) of the welding
