Mains switch ON / OFF ... with integral “Ready” indicator (lights up
when the mains switch is switched on)
Coarse step switch ... divides the open-circuit and welding-voltage
range (welding-power range) of the welding machine into 4 steps (A-
D)
Fine step switch ... divides each coarse-step range (A-D) into 7 fine
steps
Wirefeed speed dial... for setting the wirefeed speed
‘m/min’ scale ... for continuous setting of the wirefeed speed between
1 and 18 m/min in manual mode
% scale ... for making corrections to the programmed wirefeed speed
(+/- 30%) in Program Mode (depending on the wire diameter, welding
program, coarse and fine step switch)
Wire-diameter selector switch ... for selecting the diameter of wire
to be welded in Program Mode
Welding-program selector switch ... for selecting the desired welding
program, depending on the shielding gas and filler metal
Fig.5 Explanation of terms used on welding-program dial
Manual mode ... the wire-speed must be adjusted to the
welding voltage using the wirespeed dial (m/min scale)
DIN designation / alloy of the welding wire
Shielding-gas composition
and ratio of the individual
components in %
N.B! If using filler wires and / or shielding gases that deviate slightly from
the prescribed values, you can make a correction with the wirespeed dial
(% scale).
Digital-indication selector switch ... for selecting and indicating the
desired function on the digital display
- Wirespeed (command value)
- Sheet thickness (guideline value)
- Welding current (command / actual value)
Malfunction indicator ... lights up when the machine is thermally
overloaded
NoProgram indicator
- glows when the welding-program selector switch is in the “Manual”
position
- flashes if you select a wire-diameter or welding program for which
no welding data have been programmed
- flashes if you select a coarse or fine step that is not suitable for the
welding program selected; at the same time, the symbol L or H
appears on the digital indicators and
L ... overshoot of programmed welding range - turn down the
coarse and/or fine step switch to a lower setting
H ... undershoot of programmed welding range - turn up the coarse
and/or fine step switch to a higher setting
Intermediate arc indicator ... Between the dip-transfer arc and the
spray arc, a spatter-prone intermediate arc occurs. In Program Mode,
the intermediate-arc indicator lights up to warn the welder that the arc
is in this range. By changing the wire diameter and/or choosing a
different shielding-gas mixture, the welder can avoid the intermediate
arc and achieve an optimum welding result.
Hold indicator ... every time you finish a welding operation, the
actual values for welding current and voltage are stored, and the
“Hold” indicator lights up
Digital indicator ‘m/min - mm - A’ ... has different functions assigned
to it, depending on whether you are in Manual or Program Mode
Manual Mode
- Wirefeed speed (m/min) ... shows what wirefeed has been set
- Sheet thickness (mm) ... no function
- Welding current (A) ... shows the actual (or ‘Hold’) value of the
welding current
Program Mode
- Wirefeed speed (m/min) ... shows what wirefeed has been set
- Sheet thickness (mm) ... guideline value for the thickness of the
base metal
- Welding current (A) ... command value, actual (or ‘Hold’) value of
the welding current
Digital indicator ‘V - inductance’ ... has different functions assigned
to it, depending on whether you are in Manual or Program Mode
Manual Mode
- shows the command value, actual (or ‘Hold’) value of the welding
voltage set on the coarse and fine step switches
Program Mode
- shows the command value, actual (or ‘Hold’) value of the welding
voltage set on the coarse and fine step switches
- Welding-current socket 1 / 2 / 3 indicator ... When changes are
made on the coarse or fine step switch, the figure 1, 2 or 3 is shown
in the digital indicator. You must then plug the earthing cable into
the respective welding-current socket - 1,2 or 3 - and latch it in
place.
Operating mode selector switch ... for selecting the operating mode
- 2-step
- 4-step
- Intermittent 2-step
- Intermittent 4-step
- Spot welding
- Wire inching
- Gas-test
Optional push/pull mode
