Abstract
The invention provides a compact and economical welding control system having an integrated power section. To this end, a switching module is provided for the power section of a welding control system. The switching module has a switching device, at least one cooling body, a current supply and an insulating element which provides a potential-free coolant arrangement. The invention is advantageous in that the potential-free coolant arrangement allows the coolant bodies to be shortened so that less space is required inside the control system and the control system can therefore have a more compact structure. The invention enables even the requirements in terms of the coolant bodies to be reduced, allowing the use of cost-effective cooling tubes or even cooling pipes that are directly connected to the cooling body.
