By Keith Crosbie | Last Updated April 09 2020
We all have a mix of wrenches in our tool boxes. Some of us have a lot of SAE, others have a full range of metric and most of us have a balanced mix of both.
Whatever your setup, our wrench conversion chart will tell you the best fitting standard or metric wrench to use for any given bolt.

|---|---|
| 9000 , kg | 2.5 |
Purpose and scope
Standard RC welding electrodes are designed for manual arc welding of ordinary and critical structures made of carbon steels according to DSTU 2651-2005/GOST 380-2005 (St 1 St , St 2, St 3) of all degrees of deoxidation - "KP", "PS", "SP" and GOST 1050-88 (05kp, 08kp, 08ps, 08, 10kp, 10ps, 10, 15kp, 15ps, 15, 20kp, 20ps, 20).
Instructions for use
Designed for welding fillet, butt, lap joints of metal with a thickness of 3 to 20 mm. Electrodes with a diameter of 2.0 to 4 mm are suitable for welding in all spatial positions; with a diameter of 5 mm - for welding in the lower, horizontal on a vertical plane and vertical "bottom-up" positions.
Top-down welding is performed with a short arc or support, while the electrode should be in the bisector plane at an angle of 40-70 ° to the welding direction.
Welding coefficient - 8.5-9.5 g/A.h. Consumption of electrodes per 1 kg of deposited metal - 1.7 kg.

Special properties
Welding electrodes Standard RC are made according to an improved recipe that allows to provide good welding and technological properties when welding from small-sized (domestic) transformers: easy arc ignition, fine flake formation of the weld metal, easy or spontaneous detachment of the slag crust.
Can be used for tacks, short and root welds at low mains voltage.
