25. WELDING CURRENT KNOB.

Further Function: Turning this knob, while

using  button  14  and  LEDs  3  to  10,  the

welding parameters can be set.

26. LOCAL / REMOTE SELECTOR:

Local (LED 27 off) or Remote (LED 27 on)

use of the welder can be selected pressing

this button.

When in local use the welding current is set

turning knob 25.

During remote use the welding current is set

using a remote unit (optional accessory).

28. BALANCE KNOB:

TIG AC welding: 

The balance of the DC

component of the AC output welding current

can be set using thes Knob.

TIG DC/MMA welding:

Not used

29. Balance Current Confirmation: 

TIG AC welding:

This lights up for app. 4

seconds at each setting selected using of

Knob 28.

MMA + TIG DC welding:

Not used

30. Direct polarity indicator

31. Reverse polarity indicator

32. AC mode indicator

33. Polarity selector: 

Repeatedly pressing

this button alternates the output polarity .

MMA Mode:

switch between direct polarity

(LED 30 ON) (usual selection) and Reverse

polarity (LED 31 ON)

TIG  Mode:

switches  between  Reverse

polarity  DC  mode(LED  31  ON)  and  AC

mode (LED 32 on).

34. Air-intake grills

35. Welding front socket

MMA welding: 

Electrode clamp

TIG welding: 

Welding Torche

36. Remote Control Connector

MMA welding: 

Using a dedicated (optional)

accessory,  the  welding  current  can  be

remote adjusted.

TIG welding: 

A “start” or “stop” command is

relayed from the torch to the unit.

If a welding pedal (optional accessory) is

used, a suitable current level command is

also sent. (In the latter case, the torch button

is automatically disabled.).

43.  Liquid-Cooling  System  Connector

(optional accessory): 

Beware !!

The  connector  uses  dangerously  high

voltage: NEVER use it for any other use than

as described in this Manual.

3. CONNECTION TO POWER SUPPLY 

Before plugging the unit in, check the power

supply  voltage,  phase  and  voltage

frequency.

The  permissible  voltage  is  shown  in  the

“Technical  Specification”  chapter  of  this

manual and on the unit nameplate. Ensure

the  welder  is  earthed  appropriately.  Also

check that the plug provided with the unit is

compatible with the local power grid socket.

Make sure that the power supply is sufficient

to operate the welder.

The  types  of  power  supply  protection

devices  to  be  used  are  listed  in  the

“Technical  Specification”  section  of  this

manual. 

The power cable supplied with the welder

should not be extended but, if that becomes

necessary,  either  an  identical  or  greater

cross-section  cable  should  be  used

according  to  the  final  cable  length.  The

TT165 AC/DC and TT205 AC/DC models
