■ Connections at Welding Side
Refer to “Fig. 4.2 Connections at Front Face” for proper connections.
The welder is a high DC voltage start type which applies DC voltage between the electrode
and the base metal. If insulation is not made between the electrode and the base metal,
the welder is hard to start. Confirm that the welding torch, the cables at the welding side,
the cooling water path including the cooling water circulator and the weld wire are
insulated from the base metal grounding.
