RSN7-2500 Stud Welder

RSN7-2500 Stud Welder:

1. Our advantages:

(1). RSN Series Stud Welders are over ten years’ research achievements

(2). They are with advanced inverter technology, imported components as main power components, guaranteeing the excellent operation performance and high quality.

(3). Compared with ordinary stud welders, they feature lighter weight, lower power consumption, more sensitive adjustment and lower fault rate and still good performance under the lowest voltage working conditions.

2. Application: They are generally used in various aspects as the automotive, boiler, construction steel structure and ship building.

3. Features:

Welding current (Ampere) can be selected from the range of 50—100 times of the stud diameter.

That is I=（50-100）d（A）.

Welding time (Millisecond) can be selected from the range of 50—100 times of the stud diameter.

That is I=（50-150）d（ms）.

4. RSN series welders provide the arc stud welding, with the following principles:

(1), To contact the stud in the ceramic ring with the work piece.

(2), To press the welding switch on the welding torch, the welding torch shall automatically rise and welding crater shall be made by arc burning with the work piece.

(3), The welding torch shall put the stud into the welding crater after the welding time and the welding foot shall be formed after the molten iron fills the ceramic ring.

(4), The stud welding shall be finished after the welding foot solidification and ceramic removing.
