Operation
7.1
Procedure
This power source can be used for submerged arc welding and stick welding. It adopts module design, which can be used
for single wire welding, also can be used for multi wire welding, max. 6 arc welding, it can also be parallel for other
applications.
Through adjust the AC wave frequency, wave balance and DC deposition data, operation can reduce the arc deposition
and control the c half wave to affect the weld penetration, as well as the – half wave to affect the welding speed.

DCEP: Work piece voltage higher than the welding head voltage during the welding process, weld penetration high,
weld speed slow, normally used for the forward welding for tandem to ensure the penetration. Refer to above drawing (a)

Power off, refer to 6.3 connect the machine. The arc voltage inspection wire must connect well( work piece side
connect with work piece, welding head side connect with welding electrode holder)
