6 PARALLEL CONNECTION
Two pcs UWI-320TP may be parallel connected and will then supply up to 640A current for stick
electrode welding and, more important, for Air Carbon Arc gouging. This is done as follows:
-
Set both machines to MMA welding (selector switch up).
-
Set both machines to remote control and if extensions are necessary use same length
remote control cables from each machine to the work site where the remote control parallel
connection kit, product number
676973,
is used to connect both machines to the same
remote control
-
If remote control is not used both machines should be set to the same ampere value on the
displays, half of the required value for the electrode
-
Return cables from both machines should be of equal length and clamps should be
connected close together directly on a clean part of the work-piece. 70mm2 cable is
recommended. NB! Same polarity for both on the welding machines.
-
Welding cables from both machines must be of equal length to the work site where the
parallel connecting three-way connector DIX70 male-female-female, product number
632901
is used to connect both machines to the same electrode holder.
-
For Air Carbon Arc gouging plus (+) polarity should be selected to the torch, and Arc force
).should be set at maximum. ACA torch 600A (product number
528703
)
.
A connector
conversion is required here, product number
634121.
