Matt is correct. It is true, Butters AMT Ltd was put to liquidation early December 2008. A new company was also set up just prior to its liquidation (Butters AMT welding Ltd) ? A lot of the staff involved in customer service are not with the new company which could be an explanation to the seemingly suffering support.
The model you have is a pre-production machine, but a variant of the superb AMT311C, therefore no model specific manual would have been produced.
Being a previous member of Butters (up until Aug 08) and having the main involvement in the development of the 'SC' or 'Auto' series, which is what the eventual production models were to be called, I can help with an explanation of the controls. A full range of this SC model is actually available from the original manufacturer Iskra Varjenje, Slovenia....PM me.
Anyone needing any information on Butters equipment, parts, or just pointing in the right direction for equipment please do not hesitate to PM me.
Anyway...
Working vertically from Left to right (see attached panel)
1.
a. Spool - indicates machine ready for operation with Spool gun, if lit.
b. Thermometer - indicates machine overuse, if lit. will not function until extinguished.
c. Auto - if lit = Auto mode, if not = manual mode (as standard MIG machine).
d. UP arrow - cycles above indicators, if all out = manual mode.
e. DOWN arrow - cold wire feeding, to initially feed wire through welding torch.
2.
a. Volt meter
b. Ammeter - also indicates sub menus, when accessed
c. UP arrow - cycles through sub menus, for adjustment of pre gas, post gas, burn back, wire speed ramp up, spot and stitch timers etc...
3.
a. Stitch welding mode on indicator
b. Spot welding mode on indicator
c. 4T or Trigger latched mode on indicator
d. 2T or Normal Trigger mode indicator
4.
Wire trim - In Auto mode....set in central position (adjust left to decrease wire speed and right to increase as necessary)..note that one full turn gives very slight adjustment....also.. If knob pressed resets to zero
In manual mode....fully left is min wire speed..fully right max.
This dial is also used in conjunction with 'UP arrow 2c' to adjust the sub menu items.
5.
Use the UP arrow to cycle through the indicators for wire diameter being used..0.8, 1.0, 1.2, 1.6mm
6.
Use the UP arrow to cycle through the indicators for wire type/material being used..Fe (steel), Inox (Stainless), Alu (Aluminium), CuSi (Brazing)
7.
Use the UP arrow to cycle through the indicators for the type of gas in use..ArCo2 (mixed), CO2, Ar (pure Argon), No Gas
Note...The machine realises that certain combinations of 5. 6. and 7. cannot practically be achieved and some indicators will therefore be skipped in the cycles.
Note...The indicators do not illuminate, or have any function, when the machine is out of Auto mode.
The other controls are as a standard, step, MIG machine, EVEN IN AUTO MODE these have to be set for initial power settings.
0/1 = Off / On
A, B, C, D = Coarse power settings
1, 2, 3, 4 = Fine power settings
ie. lowest setting is A1 through A2, A3, A4, B1, B2 etc.to highest setting D4.
Any more help........PM me...
