ArcTractorTM Arc Voltage Sensing Dolly

Product introduction:

       Our technological revolution is to make welding easier and make your existing resources exert bigger value utilization space!

ArcTractor® is a kind of automatic welding tractor integrating arc voltage sensing wire feeder and automatic walking mechanism. Its working voltage is the arc voltage outputted by welder power, so there is no need to provide additional operating power. It is suitable for CC/CV automatic submerged arc welding and can achieve automatic gas shielded arc welding, automatic open arc surfacing welding, TWINARC, strip surfacing welding and hot-wire submerged arc welding by matching different welding heads. It is applicable to φ1.6-φ6.0 solid wire and flux wire. A number of patented technologies have been granted to it.

Main Features:
It has two ways of arc starting, namely COOL START and HOT START, and the arc starting performance is good;
Without need of control cables, it can match any brand of DC CC/CV welders, thus avoiding the equipment failure caused by the short circuit and open circuit of control cable and the instability of the welding process caused by cable extension.
Four-wheel drive ensures reliable wire feeding;
The change of common DC manual welding and common MIG/MAG into automatic MIG/MAG or automatic SAW improves production efficiency and welding quality and reduces labor intensity;
A variety of mechanical structures share same kind of control technology, and the controller is in good compatibility and can easily be maintained.
It can realize automatic flux-cored wire constant current gas shielded welding by matching common DC manual welder. This leads to the ideal welding of equal penetration and equal arc length that is especially suitable for the use in such fields as high-strength steel, shipbuilding, port machinery and pressure vessel;
It can realize large-current automatic solid wire constant current gas shielded welding by matching common DC manual welder. After adding solder filling device, it can become automatic submerged arc welding. It is chiefly applied to such sectors as small and middle-sized pressure vessels and petrochemical storage tank.
It can realize high-speed and high-efficiency automatic welding by matching common MIG/MAG welder. It is particularly suitable for sheet metal welding, like the welding in container industry (the highest welding speed can be up to 2m/min);
It can realize automatic gas shielded arc welding or automatic submerged arc welding by matching arc welding generator, which is used in the marine and offshore engineering;
In terms of open arc surfacing welding, it is suitable for the welding of abrasion/corrosion resistant materials. It features high deposition efficiency and low dilution rate.
