Frequently Asked Questions
Can It Crimp Insulated Terminals Safely With an Adapter?
No; he notes it cannot safely crimp insulated terminals with an adapter. Using recommended crimping techniques and proper tools with safety features for insulation is advised, as the indent hammer lug design lacks insulation-specific safety.
Can I Use It on Stainless or Copper Lug Materials?
Yes. He can crimp copper connections effectively; stainless steel lugs are harder and may require heavier hammer blows or pre-piercing. Proper technique and inspection are advised to ensure secure crimping and avoid deformation or poor contact.
Is a Carry Case or Storage Pouch Included?
No, a carry case is not included. The description notes no carry case; users recommend aftermarket storage options such as a small tool pouch, padded roll, or compartment in a toolbox to protect the hammer lug crimper during transport.
Are Replacement Die Inserts Available From TEMCO?
Absolutely — replacement parts exist! He notes TEMCo offers limited replacement die inserts; users should verify die compatibility with part numbers and wire gauges, contacting TEMCo support or the vendor to confirm availability before purchase.
Can It Be Used Effectively in Tight or Confined Spaces?
It can be used in tight spaces but may face maneuverability issues; its compact body helps reach confined areas, yet reliance on a hammer or vise and clearance for swinging limits effectiveness compared to dedicated low‑clearance crimpers.
