MMA welding

If welding is performed alternately by different methods, e.g. TIG, MIG/MAG or MMA and if
one or two welding torches and an electrode holder are connected to the machine, the
open-circuit/welding voltage is applied simultaneously to both!
Therefore, always place the torch and the electrode holder on an insulated surface before
starting work and during breaks.
• Adjust the appropriate changeover switches to the following settings:
TIG
MMA
This machine has the following features in electrode operation:
Arcforcing
Shortly before the electrode threatens to stick, the arcforcing device sets an increased current
designed to impede sticking of the electrode. The value of the current increase depends on the
arcforce setting. Excellent welding properties are achieved with all difficult electrodes by adjustable
arcforcing.
Hotstart
The hotstart device has the effect of better ignition of the stick electrodes by an increased ignition
current.
Antistick
If the stick electrode sticks in spite of the arcforcing device, the machine automatically switches
over to the minimum current within about 1 sec, so that overheating of the electrode is prevented. If
the antistick device has responded, check the main current setting and if necessary correct it.
