The welder has the following functions:
1. Adjust welding pressure evenly.
2. Stepless adjusting the welding speed
3. Freely adjust the current and heat
When upper and lower weld rollers wear out, adjust the hand wheel above the pneumatic cylinder to keep the original distance.
The working principle of the welder are as follows:
The sheet is put between two welding rollers (the ends of the sheet will be lapped), with pressure, the welding rollers turn. With low voltage, big current and resistance radiation, the two short-cut poles generate heat which connect the working piece.
With special fixture, the FN1-200-5 seam welder can weld steel drum directly without spot-welding.
