NOTE! If connections cross, cooling liquid is circulating to wrong direction in torch and torch
handle and neck body might be considerably heatened.
2.1.7 Use as terminal unit
Between power source and the Protig 410 unit are available 10 m interconnecting cables
which are inside of mutual power.
On page 5 are shown following mecanical operations which are involvel in use of unit.
2.1.8 Assembly and controls of MIG / TIG / MMA equipment
Connecting cables are shown on page 7 (liquid-cooled).
Circulation systems of liquid-cooled torches are series connected. Read carefully warnings in
paragraph 6.
Do not forget to change polarity according to paragraph 5 when you go over from MMA
welding to TIG welding.
Equipment will automatically select Mig welding method and controls when you press
operation switch of Mig gun and respectively TIG welding method when you press switch of
TIG torch.
Remote controls for Mig or TIG welding operate from remote control units which are
connected to respective Promig 501/511/530 and Protig 410 units.
You can select MMA welding from panel of one or the other unit, when remote control for
MMA welding is operating from remote control unit which is connected to device in question.
NOTE! At welding and at no-load of MMA welding also other welding tools are exposed to voltage
depending on polarity. Be careful that welding tools won`t produse any short-circuits.
2.1.9 Remote control units
Connect remote control unit as shown in figures on page 5 or 6. Operation of remote control
unit is explained on page 21.
2.2 INSTALLATION OF TIG/MMA EQUIPMENT
Fasten earthing press of ground cable carefully, preferably direct to welding piece. Contact
surface of press always should be as large as possible.
Clean the fastening surface from paint and rust!
Use in your TIG/MMA equipment 50 mm
2 cables. Thinner cross-sectional areas might cause
overheating of connectors and insulations.
Make sure that the torch being in your use is designed for max. welding current needed by
you! Never use a damaged torch!
2.2.1 Choice of electrode and flow amount of shielding gas
Use argon as TIG shielding gas. Electrode size and shielding gas flow rate are defined by
welding current size. The table below is given only as a guide.
