The WM-3238 is a 2.0 kg pneumatic crimping tool that puts 1.3 T (1,300 kgf) of crimping force behind a swappable die module, covering wire from 0.25 to 6.0 mm² at about 1,200 crimps per hour. It runs on 0.5–0.6 MPa shop air through the supplied regulator and foot switch, so the operator keeps both hands on the wire. The whole tool measures 230 × 187 × 100 mm and clamps to a bench bracket, and changing terminal family means changing the die module rather than the machine.

Specifications

Key features

• Die modules swap out in the head — a different terminal family means a different die block, not a different machine
• 1.3 T (1,300 kgf) of crimping force from an air cylinder running on ordinary 0.5–0.6 MPa shop air; no motor and no electrical connection
• The supplied pressure regulator sets the air, and therefore the crimp force, to one repeatable value instead of leaving it to the operator's hand
• Foot switch keeps both hands free to hold the wire and the terminal; a pressure-protected foot switch is available where an accidental step must not fire the tool
• About 1,200 crimps per hour at the bench — roughly one crimp every three seconds without hand fatigue
• Chrome-vanadium die steel, oil-hardened, so the crimp profile holds its shape over long die life
• 2.0 kg and 230 × 187 × 100 mm — small enough to carry to the job and light enough to reposition on the bench all day
• Clear guard sits over the die area, and the black base bracket bolts the tool down or lets it sit on its rubber feet

What it processes

• Bench crimping of insulated and non-insulated terminals on control panel, appliance and machine wiring
• Maintenance and field service work where mains power is not available but shop air is
• Small-batch and prototype harness shops that change terminal types often and want to change only the die block
• Replacing hand crimping pliers where crimp-to-crimp consistency and operator fatigue have become the problem

Suited for: operator-fed crimping of 0.25–6.0 mm² wire at a bench or on site, where terminal types change often enough that a swappable die block is worth more than a fixed profile — 1.3 T of air-driven force, foot-switch triggered, 2.0 kg, no electricity needed.

Not suited for: production runs measured in thousands of leads — 1,200 crimps an hour is a hand-fed rate, and an operator still strips every wire. For continuous ferrule work move to the WM-397 e-tube terminal crimping machine, which strips, twists and crimps 0.3–6 mm² bootlace ferrules automatically at 1,000–1,300 pcs/h. It is also not a reel-fed press: chained terminals on a reel with an OTP-style applicator belong on the WM-3229 cast iron frame terminal crimping machine (2 T, loose and continuous terminals) or the WM-3102T low-noise terminal crimping machine (2.0 T, 30 mm stroke, OTP transverse/positive/reverse and 2000# applicators). If you only ever crimp tubular ferrules and want one die for the whole range including the fine sizes below 0.25 mm², the WM-398 benchtop pneumatic crimper covers 0.08–6 mm² steplessly. Above 6 mm², copper cable lugs need the WM-3218 13-ton hydraulic cable lug crimping machine (0–75 mm²) or the WM-3135T 35-ton servo cable lug crimping machine (up to 120 mm²).
