- As Weld Using

Adapted by Hermit
when hiking or due to a sudden maneuver, the irons are broken and sometimes we are far from a shop where welding power something broken or filled with solder cracks. For these cases there is the emergency welding developed by yiperos batteries.

But how is it possible to weld with batteries? ... good, considering that an electrode of 3.25 mm need 120 amps for proper welding and a minimum of 24 volts, can be welded with reasonable certainty whether we add 3 batteries connected in series. Work better if you have batteries in top condition or additional winches are used to power or auxiliary lights.
reference, starting a diesel engine needs something like 300 amps, and a winch can draw 400 amps. to operate at full capacity, then the three batteries amperage there enough capacity to weld.
almost no risk of electrocution. But wear gloves and do not stand on a wet spot. If the welding is attached to a vehicle, the better off the battery. Protect sensitive parts and paint from welding sparks.
Be sensible and take all proper safety precautions.
This is what is needed for welding with batteries:
- Various cables to connect the terminals in series (the famous current tap). If not enough, engineer unions, using thick cable that if ( see photos).
- Electrodes: the common arc welding.
- clips to hold the electrode and to make dough in pieces. A good alligator helps a lot to hold the electrode or wiring.
- 3 batteries at least.
- A dark glass solder mask (required) to protect the view of the weld (it is very harmful to the eyes).
- Security : battery cover with the rubber on the floor and away as possible from where we are working to prevent sparks inflammation (batteries emit a flammable gas). Solder for short periods. Cool the batteries after each weld. If it sticks to the electrode and does not want to drop off quickly clip the terminal of the battery.
Given certain characteristics of the parts or situations of the moment, it may be convenient for the welder to the electrode to the ground instead of positive, as seen in the images. This improves the weld penetration (valid for electrodes 6010/6011).


batteries need not be exactly the same type or size. If there are no clips to use what is at hand, but ensuring a good contact.


With two batteries, ie, 24 volts, it can work but will be very difficult to maintain the welding arc, unless it is very good welder. In the picture you can see the available live and direct.


The photo shows a yipero in full reconstruction of a cardan, starting from a water pipe ... original drive shaft broke and twisted into two parts.
As you can see, it works!, So practicing at home and with someone who seoa welding so that output can meet any eventuality.
