Projection resistance welding machine MR-70.07 is intended for AC welding of parts from low carbon steels, stainless steels, as well as copper busbars with welding tape thickness of 0.1; 0.2 and 0.3 mm. Maximum cross-section area of welded parts is 100x50 mm with maximum welding tape thickness of 15 mm.
Advantages of the machine MR-70.01 NF 4:
- welding current regulation when supply voltage changes;
- productivity up to 180 weld./h (several folds greater than soldering);
- no need to use copper-phosphorous and silver solders;
- reducing of labor intensity;
- stepped-phase adjustment of welding current;
- discrete adjustment of welding operation positions;
- regulator which displays the number of weldings and total operation time;
- operating in automatic and single cycle mode;
- pneumatic electrode pressure system with constant, increased and forging force;
- upper electrode travel adjustability;
- thermal protection;
- valve mufflers;
- the machine is fitted with Camozzi pneumatic equipment;
- using of an own-produced transformer TKE-140 NF4.
When welding of flexible copper busbars of large cross-section (100x100x15 mm) is considered necessary, it is required to use the MRV-70.01 NF 4 welding machine with DC supply and more powerful pneumatic cylinder.
